CAO - Cannabis Sales Outlets Mayor Isbester read the following written comments that had been submitted to the Town, but were not read at the public meeting on January 24, 2019:
Valerie Watts-Dafoe: I am not able to make the meeting tomorrow evening, but I did want to put my support behind allowing cannabis retail stores in our community. Right now they are new and some feel controversial, but in a few years they will be viewed as similar to the LCBO. I do not want to see the community lose the opportunity to keep residents shopping local. If they are heading to Kingston or Belleville to purchase cannabis, they will likely be purchasing other items (groceries, clothing) there as well. I would rather see those dollars spent in our community.
Steve and Deb Lowry: Sorry to miss this important meeting. We would have preferred retail access via LCBO type outlets and consider the Province's Jan. 22nd decision deadline to be unreasonable, but that's another topic. We are supportive of allowing retail outlets in Greater Napanee: - cannabis is now a legal commodity - saying no would present a barrier to access for members of our community who wish to legally purchase it - the Town has already permitted a large-scale cannabis manufacturing company to establish operations here. To deny retail operations would appear contrary. - the Province's 150m proximity to public schools is not sufficient and we hope the Town will advocate for additional controls on location (parks and recreation facilities, private schools, etc.). - The Province talks about additional funding for policing and public education. Both are important and any funds should be split equally. - the many, illegal retail outlets to the West should be a concern for all of us. If the Province hears from all local municipalities that enforcement of their legislation is needed, perhaps some action will be taken.
Raymond Callery, CAO reviewed the four questions to be considered by Council: 1. Does Council wish to opt out of sales locations prior to January 22, 2019? 2. Does Council wish to develop clear policy on providing guidance to the AGCO in their licensing considerations? 3. Does Council want to invest in specialized mapping of “appropriate locations”? 4. Does Council want to investigate temporary staffing or consulting resources in 2019 to deal with the possible demands of: ▪ Meeting 15 days response requirements of the AGCO. ▪ Enforcing Building and Fire Code requirements in these facilities. ▪ Enforcing other issues that may arise from cannabis usage.
Mayor Isbester asked for Council’s comments.
Councillor McCormack stated that if Council decides to opt in he would suggest Council hold another meeting to discuss staffing resources, mapping and a policy for review of the cannabis retail sales outlet applications and then send this information to the province.

Regular Session of Council - January 22, 2019 Page 8 of 326 REGULAR SESSION OF COUNCIL - January 22, 2019 Minutes
Councillor Richardson stated: ▪ his concerns are for the vulnerable sector areas; ▪ that the Town loses control over being able to police the cannabis retail sales outlets; ▪ that it appears the Town will not see a cannabis retail sales outlet for one to two years; and ▪ that if the Town opts in, policies and specialized mapping are needed.
Councillor Pinnell stated: ▪ his agreement with the CAO and other speakers that the Town has time; ▪ that all four questions need to be acted on; ▪ specialized mapping has been done well and shows that there are only a couple of locations (commercial zones) that are within the 150 m setback from schools; ▪ that if Council opts in, it is only a matter of time until a cannabis retail sales outlet opens here; and ▪ that standardized questions in a policy for review of the applications are needed.
Councillor Norrie stated: ▪ that he agreed with comments made by other Councillors; and ▪ considering that the Town has 2 manufacturers, 3 wine stores, a distillery and whiskey distributer, he doesn’t see how Council can opt out.
Councillor Johnson stated: ▪ that it has been interesting to talk to people about this issue and to see how the public’s comments have changed when they realize that cannabis retail slaes outlets are legally coming; ▪ that it is difficult for the Town to not have control over where the cannabis retail sales outlets will be located; and ▪ that it is good to start discussion tonight and bring back to next meeting for the policy discussion.
Deputy Mayor Kaiser stated: ▪ that he is in favour of opting in; ▪ that he doesn’t think there is a lot of opposition from the public; ▪ clear parameters and lens to review applications are necessary; ▪ that he agrees that the specialized mapping is already in place; and ▪ that temporary staffing for the additional workload of reviewing applications would not be needed in 2019; and ▪ developing clear guidelines and policy for the review of the applications can be managed in house.
Mayor Isbester stated that she is in favour of opting in and would like to see the Council resolution include the Town’s concerns and any additional restrictions.

Staff Report to Council
To: Mayor Isbester and Members of Council
Date: February 12, 2019
Prepared By: Michael Nobes, Director of Development Services
Presented By: Michael Nobes, Director of Development Services Re: Infrastructure Services – Cannabis Retail Outlets, Land Use & Municipal Policy Statement on Cannabis
Staff Recommendation: That Council receive for information the Infrastructure Services – Cannabis Retail Outlets, Land Use & Municipal Policy Statement on Cannabis report; And further that Council authorize staff to begin creating the mapping for use in providing the Alcohol and Gaming Commission of Ontario (AGCO) with comments on cannabis retail outlet license applications; And further that Council adopt the Municipal Policy Statement on Cannabis for use in providing the AGCO with comments regarding retail outlet license applications.
Financial Implications: The estimated cost associated with digitization of the mapping is $1,500.
Accessibility Implications: This report may be available in alternate format upon request.
Information Technology Implications: Upon review, there are no information technology implications.
Energy Management Implications: Upon review, there are no energy management implications.
Background Information:
This report is intended to explain the staff resources required to produce clear mapping to indicate the desired 150m setback of cannabis retail outlets from schools and the additional sensitive land uses as identified in Resolution #39/19.This mapping will be used to provide the AGCO with comments regarding cannabis retail outlet license applications. In addition, the proposed Municipal Policy Statement on Cannabis will be presented for use in the review of cannabis retail outlet license applications to provide
1
Infrastructure Services - Cannabis Retail Sales Outlets Mapping, Staffin... Page 27 of 326 the AGCO with comments within the 15 day review timeline. Lastly, information will be presented for Council’s consideration regarding commercial production & processing as well as personal cultivation
Council has shown a desire, over-and-above the provincially-regulated 150m setback from schools, to apply a 150m setback from additional sensitive land uses that cannabis retail outlets are not desired to locate. The non-exclusive list of sensitive land uses includes:
• Navigable waterways where launches, public docking, patios, public green space, or gathering spots of children are encouraged; • Public Parks, Recreation Facilities, Playgrounds; • Churches or Sunday Schools; • Registered Day cares or Youth Centres; • Places providing any type of Mental Health or Addiction Services; • Shelters, Protective Residential Locations, Warming Centres; • Municipal Offices; • Public Farmers’ Market Spaces; • Interchanges of roads owned or controlled by the MTO; • Police Stations, Fire Departments or Ambulance Services; • Correctional Facilities, Youth Detention Facilities and Probation and Parole Offices; and • Locations for remembrance gatherings such as Funeral Homes, Cemeteries and War Memorials.
It is recommended that the desired mapping not apply a blanket setback to all zones that could permit one of the sensitive land uses noted. Rather, staff propose assessing land uses within 150m of any retail-permitting zone to determine where the sensitive uses under consideration are currently located in proximity to possible outlet locations. The setback could then be applied to the maps accordingly on a site-specific basis. For example, a day care facility may locate in any “Residential” or “Community Facility” zone and in any urban “Commercial” zone. If the setback were applied to future-proof these areas against cannabis retail outlets, this would eliminate almost all locations that an outlet could be established.
Discussion:
Mapping:
Staff have proactively mapped all locations that permit retail establishments. It is proposed that this mapping be used as a baseline for creating the more thorough maps to include the sensitive land uses as identified by Council and the associated setbacks. As previously noted, staff propose performing site assessments within 150m of retail-permitting zones to efficiently identify the sensitive land uses in proximity to potential cannabis retail outlet locations.
2
Infrastructure Services - Cannabis Retail Sales Outlets Mapping, Staffin... Page 28 of 326 The mapping will identify present-day sensitive uses. However, over time, some of the listed sensitive uses may be established after the mapping has been completed, or Council’s list of sensitive uses may change. Staff propose performing an inventory check of sensitive uses on a 6 month basis. This will ensure that the mapping is kept up-to-date and reflects any changes to the sensitive land uses noted in the municipal policy statement on cannabis. The Emergency Services Department is able to assist with performing ongoing inventory checks of sensitive uses during routine door-to-door Fire Code site inspections.
The table below identifies the anticipated staff hours and consultant costs required to create the mapping.
Task Estimated Staff Additional Staff Time/Cost Resources Required? Identify sensitive uses 35 hours No within 150m of retail-permitting zones (includes site visits) GIS technician to create $1,500 Yes mapping based on information provided by staff Checking/Approval of 14 hours No maps Review and prepare 4 hours No comments for the AGCO per license application
Ultimately, the bulk of the time and cost to create the requested mapping will be front end loaded. Development Services staff time will be required to verify sensitive uses adjacent retail-permitting zones on a semi-annual basis with minimal consultant costs associated to update the digitized mapping, if required.
Municipal Policy Statement on Cannabis:
As part of the legislative framework, the province is allowing municipalities and the public to provide input on retail store applications to the AGCO. The comments are intended to express whether the proposed store is in the public interest. The relevant matters of public interest, as defined by O. Reg. 468/18 under the Cannabis License Act, include:
• Protecting public health and safety • Protecting youth and restricting their access to cannabis • Preventing illicit activities in relation to cannabis
3
Infrastructure Services - Cannabis Retail Sales Outlets Mapping, Staffin... Page 29 of 326 Staff believe that the provincially-mandated minimum separation distances from schools and recommended distances from other sensitive uses, as per the cannabis policy statement, should help address the above-noted matters of public interest.
To provide the AGCO with consistent and timely input from the Town, staff are recommending that Council endorse the attached Municipal Policy Statement on Cannabis. Staff have utilized the template for a cannabis policy statement as provided by the Association of Municipalities of Ontario (AMO). The AGCO will consider comments in the decision-making process, though it does not mean that it will influence the final decision to approve or deny a retail license application.
When the proposed mapping is created, staff intend to send the Municipal Policy Statement on Cannabis along with the maps to the AGCO for their information in assessing license applications.
Cannabis-Related Zoning Matters:
Presently, the Town’s Zoning By-Law only contemplates production, processing and packaging/shipping of medical marijuana and does not consider these aspects for recreational cannabis. Licensed medical marijuana producers will automatically be permitted to produce recreational cannabis under their license issued by Health Canada. A staff-initiated zoning by-law amendment will be required to address the production, processing and packaging/shipping of recreational cannabis.
Presently, a medical marijuana production facility is only permitted in the Light Industrial and General Industrial (M1 & M2) zones. Development Services staff have received several inquiries from the public regarding commercial production in zones outside of the M1 & M2 zones. A keen interest lies in zones such as: Business Park (BP) and Rural Industrial (M3). There is a growing interest in the outdoor (open-air) production of cannabis in addition to production at the micro scale (less than 200m2 [2,150ft2] of canopy space). These aspects may be of interest for Council to explore during the upcoming zoning by-law amendment.
It may also be of interest to Council to consider personal recreational cannabis cultivation. Council may wish to consider:
1) Treating personal cultivation as an accessory use (i.e. no specific changes to the zoning by-law would be required) 2) Treat as an accessory use but create additional requirements such as: • Location that plants can be grown (i.e. indoors, outdoors, yards, etc.) • Required building/yard security & odour measures
The above noted information will be expanded upon in a subsequent, more detailed, report to Council.

Infrastructure Services - Cannabis Retail Sales Outlets Mapping, Staffin... Page 30 of 326 Town of Greater Napanee Municipal Policy Statement on Cannabis
Adopted by Council: Effective Date:
1.0 Purpose & Vision a) The purpose of this policy statement is to provide input related to proposed cannabis retail outlets to the Alcohol and Gaming Commission of Ontario (AGCO) as well as help prospective recreational cannabis retailers in their consideration of location of cannabis retail stores in The Town of Greater Napanee. b) It is recognized that the AGCO is the provincial authority that licences cannabis retail operators, authorizes cannabis retail locations and licenses senior store staff. The AGCO regulates and reviews all aspects of the retail operation including municipal and public input and that the proposed store location is consistent with the public interest as defined in the regulations. c) The Town of Greater Napanee has chosen to allow retail sales of recreational cannabis within retail-permitting zones. The following provides staff with guidance on commenting to the AGCO when notice of a proposed cannabis retail store site is provided.
2.0 Principles for Cannabis Retail Store Locations a) For the purposes of this policy statement, a cannabis retail store shall mean a store licensed by the AGCO. b) The provincial licensing process does not remove the requirement to comply with the zoning by-law and other municipal planning documents. The definitions within the municipality’s Official Plan and Zoning By-law are applicable to all retail, including cannabis retail stores. Retail sale of cannabis from a provincially licensed store is legal and is a permitted use in the retail-permitting zones. c) While the licencing of the store operation is the responsibility of the AGCO, the Building Code applies to cannabis retail store locations. Therefore, where a building permit is required, the building inspector will undertake duties as usual. Fire Code compliance is also mandatory.
Infrastructure Services - Cannabis Retail Sales Outlets Mapping, Staffin... Page 31 of 326 Town of Greater Napanee Municipal Policy Statement on Cannabis Page 2 of 2
3.0 Cannabis Retail Stores and Sensitive Activities a) The goal of this Policy is to ensure: public health and safety is addressed, protection of youth is achieved, and illegal sales are diminished. Retail cannabis stores are discouraged where nearby properties are designed to serve youth including: youth centres, registered day cares, playgrounds, public parks, recreation facilities, as well as other sensitive facilities that provide any type of mental health or addiction services. b) Cannabis retail stores should not be permitted within 150m of the sensitive areas listed below: i. Navigable waterways where launches, public docking, patios, public green space, or gathering spots of children are encouraged; ii. Public Parks, Recreation Facilities, Playgrounds; iii. Churches or Sunday Schools; iv. Registered Day Cares or Youth Centres; v. Places providing any type of Mental Health or Addiction Services; vi. Shelters, Protective Residential Locations, Warming Centres; vii. Municipal Offices; viii. Public Farmers’ Market Spaces; ix. Interchanges of roads owned or controlled by the MTO; x. Police Stations, Fire Departments or Ambulance Services; xi. Correctional Facilities, Youth Detention Facilities and Probation and Parole Offices; and xii. Locations for remembrance gatherings such as Funeral Homes, Cemeteries and War Memorials. c) Attached is a map showing the retail-permitting zones of the municipality and the sensitive uses identified in Section 3.0 b).
4.0 Comment Preparation & Submission a) When preparing comments to be submitted to the AGCO, planning staff shall have regard for: i. Ensuring zoning allows a retail establishment as a permitted use and whether the provisions of the zone can be satisfied; ii. The separation distances listed in Section 3.0 b) of this Policy are met; and iii. The goal of Section 3.0 a) is met. b) Time limits do not make it practical to bring a report before Council, the Director of Development Services, or designate, is delegated the responsibility to submit comments to the AGCO on behalf of the Corporation. Regular updates are to be provided to Council regarding correspondence with the AGCO.

Executive Summary
The A.L. Dafoe Water Treatment Plant is a conventional design, chemically assisted filtration plant that treats water drawn from Lake Ontario and supplies drinking water to approximately 8500 residents of the town of Napanee. Reliability of the system is supported by continuous monitoring instrumentation, process alarms, and critical equipment redundancy.
During 2018, the volume of treated water provided to the community was increased by approximately 21 percent when compared to that produced during 2017. Average day flow measured in 2018 was approximately 46 percent of the plant design capacity of 10,450 m3/d, while the maximum day flow amounted to approximately 81 percent of that capacity.
Water samples collected throughout the process are tested for over 80 different parameters to evaluate treatment efficiency and to ensure finished water quality. Target parameters range from critical indicators related to potential acute health effects to non-health related parameters that aid in assessing process performance or the aesthetic quality of the drinking water. All test results from samples collected during 2018 met the stringent requirements of the Ontario Drinking Water Quality Standards.
In addition to ongoing routine preventive maintenance practices, notable improvements during 2018 included: • Replacement of 175 residential water meters to improve the monitoring of water usage and to aide in reducing water loss.
• Within the distribution system, the watermain on Dundas Street underwent construction which included complete replacement of approximately 320m from the Centre Street intersection, easterly to just West of the Adelphi Street intersection.
The Town of Greater Napanee has successfully implemented a quality management system that continues to conform to the requirements of the Ontario Drinking Water Quality Management Standard. Implementation of the system demonstrates the Town’s commitment to continual improvement.

1 Description of the Treatment Process Raw Water Supply
Two pumps located at the Lake Ontario Pumping Station (County Road 21 and Highway 33), referred to as low lift pumps, are used to transfer raw water from Lake Ontario to the treatment plant. Only one pump operates at any given time, while the second is reserved for backup duty. The low lift pumps draw directly from a screened intake crib (to prevent passage of large debris) located 50 meters offshore. The low lift pumps discharge through approximately 16 km of 500 mm diameter pipeline to a reservoir located at the corner of Golf Course Lane and County Road 8. In the event of a power interruption, the low lift station is equipped with switching gear that accommodates direct connection to a mobile diesel generator.
The current capacity of the raw water reservoir is approximately 450 m3. Raw water flows by gravity through a 400 mm diameter pipe from the reservoirs to the treatment plant. The flow of raw water from the reservoir is controlled by the volume of treated water stored at the plant. As water is used by the community, valves open to allow raw water into the process to replenish the treated water reserves.
If circumstances arise that prevent the transfer of raw water from Lake Ontario, the treatment plant inlet valves can be manually adjusted to draw from the Napanee River.
Pre-chlorination / Zebra Mussel Control
The addition of chlorine to the raw water supply is called pre-chlorination, and serves three main purposes:
1. prevent biological growth within the raw water pipeline and reservoirs,
2. provide initial disinfection,
3. control the growth of Zebra Mussels
The growth of Zebra Mussels (an invasive species in the Great Lakes), if not controlled, can accumulate and eventually plug the raw water intake pipe. Chlorine is added to the raw water through a diffuser located within the raw water intake crib to control growth in the immediate area of the intake pipe. Chlorine pumping is activated only when the low lift pumps are running to avoid excessive accumulation of chlorine concentration in the aquatic environment surrounding the intake crib. The intake crib was last inspected, cleaned and repaired by an underwater inspection contractor in February 2018.

Coagulation / Flocculation / Sedimentation
Aluminum sulfate (liquid alum), which acts as a coagulant, is added to the incoming raw water upstream from the flocculation tank. The coagulant converts dispersed and colloidal solids suspended in the raw water (measured as turbidity) to small visible clumps. The coagulation reactions occur very rapidly as the alum and process water mix together within a static mixer. As the coagulated process water passes through the baffled flocculation tank, the coagulated clumps collide, forming larger clumps commonly referred to as floc.
Following the flocculation tank, the process water flows into large rectangular sedimentation tanks where velocity is decreased allowing the relatively heavy floc particles to settle by gravity. Accumulated floc (alum sludge) from the bottom of the sedimentation tanks is discharged to the waste residuals treatment process (described in more detail below). The upper, clear portion of the sedimentation tank flows to the filters for further treatment.
Coagulation, flocculation and sedimentation are treatment processes which together serve as a barrier to the passage of potentially harmful organisms by removing turbidity from the water.
Filtration
Overflow from the sedimentation tanks flows to the top of the filters. Flow moves downward through two parallel dual media filters comprised of a top layer of granular activated carbon (GAC) overlying a lower layer of sand.
The GAC layer adsorbs compounds that cause taste and odour as well as other trace organic compounds sometimes present in the raw water supply. GAC is effective in removing algal toxins such as those produced by blue-green algae.
Filtration, which takes place in the sand layer, physically removes suspended particles, including floc which may carry over from the sedimentation tanks. The filtered water passes through the filter under-drain and into storage reservoirs, commonly referred to as clearwells.
Debris which accumulates on the filter media must be periodically removed by a procedure called backwashing. During backwashing, the filter is isolated from the process and treated water is pumped upward, (reversed from normal filter flow), expanding the media bed and loosening accumulated debris. The backwash water with loosened debris is discharged to the waste residuals treatment process.

Infrastructure Services (Utilities) - Annual Compliance Reports Page 45 of 326 A.L. Dafoe (Napanee) Drinking Water System - 2018 Annual Report 11
Disinfection (Chlorination)
Chlorine, in the form of liquid sodium hypochlorite, is added to the process in two locations. Raw water is chlorinated to control the growth of Zebra Mussels and to limit biological growth in the raw water pipeline and reservoir.
The second point of chlorine addition, referred to as post-chlorination, occurs immediately upstream from the treated water clearwells. Post-chlorination serves as the final barrier ensuring that potentially harmful organisms do not enter the town distribution system. A sufficient dosage of chlorine is added at the purification plant to achieve the required disinfection CT and to maintain a residual concentration throughout the distribution system. Distribution chlorine residual prevents biological growth within the distribution piping.
Treated Water Storage Tanks and Pressure Booster Stations
Treated water is pumped from the treated water clearwells into the distribution system. Constant pressure is maintained in the central area of the distribution system by the water column height in the two treated water storage tanks, both integral components of the distribution system. The storage tank which was constructed in 2012 is located on County Road 2 and provides 4600 m3 of treated water storage capacity, while the older elevated storage tank on East Street provides approximately 1100 m3 of treated water storage capacity for use during periods of high demand and for community fire protection.
The distribution system also includes two pressure booster stations. The booster stations house inline pumps that restore adequate water pressure to areas distant or elevated in relation to the treatment plant or storage tanks. One station is located on McCabe Street to overcome the head-loss caused by the relatively higher elevation at the southern extreme of the distribution system. The second station is located on Community Road and maintains pressure to the industrial area north of Highway 401.
Treatment Chemicals
Two chemicals, sodium hypochlorite and aluminum sulfate, are used in the A. L. Dafoe Water Treatment Plant process.
Sodium hypochlorite is added for pre-chlorination and Zebra Mussel control at the Lake Ontario Pumping Station, and for post-chlorination disinfection at the treatment plant. The sodium hypochlorite solution contains approximately 12 percent chlorine, and meets the standards of the Canadian General Standards Board and American Water Works Association (AWWA) B300-10 for use in drinking water.

Aluminum sulfate, also known as liquid alum, serves as a coagulant in the treatment process. (Refer to subsection describing coagulation / sedimentation.) The liquid alum meets all specifications for AWWA B403- 16 and the National Sanitation Foundation Standard 60 for potable water use at a maximum dosage of 150 mg/L.

Waste Residuals Treatment
Waste residuals generated through the treatment process include filter backwash water, sedimentation tank sludge, and other wastes discharged during tank maintenance. Those waste streams are directed to the waste equalization tank. From the equalization tank, the blended waste is pumped to the waste residuals treatment process described below. A process flow diagram is provided on the following page.
The waste stream enters the residuals treatment process into a draft tube. The draft tube is a vertical cylindrical chamber equipped with a rotating turbine. Polymer is added to the process as a coagulant aid to produce sticky floc particles that clump together particulate matter present in the waste. Floc formation is enhanced by the mixing and shearing action of the turbine. The process stream (with floc particles) is drawn upward by the turbine, over the top edge of the draft tube. Flow then moves at a decreased velocity under one baffle and over a second baffle. The gentle mixing created by the baffles causes the relatively small floc particles to gather, (becoming larger and heavier), prior to entering the settling compartment.
The top portion of the settling compartment contains inclined settling tubes designed to maximize the settling velocity of the floc as flow passes through. The floc settles to the bottom of the settling compartment, while the clear liquid at the top of the settling zone is discharged to the Napanee River. Prior to discharge, the liquid is measured for chlorine residual and suspended solids, and if required, it is dechlorinated before it is released to the Napanee River. Recirculation of settled floc from the bottom of the settling compartment back to the draft tube enhances flock formation in the incoming wastewater at the beginning of the process. Excess accumulation of settled floc is pumped to the sanitary sewer for further treatment at the Napanee Water Pollution Control Plant.

Origins and Types of Contaminants
As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and can pick up foreign substances resulting from the presence of animals or from human activity.
The types of contaminants that may be present in source water include:
• Microbiological contaminants, such as pathogens, may come from septic systems, livestock, sewage treatment plants and wildlife. Microbiological quality is the most important component of drinking water quality because of its ability to cause acute illness in consumers.
• Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
• Organic contaminants can be naturally occurring, but most organic compounds of concern are man- made. Pesticides and herbicides are included in this group and may originate from a variety of sources such as agriculture, urban storm water runoff, and septic systems.

Infrastructure Services (Utilities) - Annual Compliance Reports Page 50 of 326 A.L. Dafoe (Napanee) Drinking Water System - 2018 Annual Report 16
Multiple Barriers to Microbiological Pathogens
Potentially pathogenic (disease causing) organisms are removed from the raw water source by the following processes:
• pre-chlorination
• coagulation / flocculation / sedimentation
• filtration
• post-chlorination
• distribution system chlorine residual
Laboratory Testing
Ontario Regulation170/03 and the Municipal Drinking Water License issued for the plant dictate the sampling and monitoring requirements for the Napanee facilities. Water quality is tested routinely throughout the treatment process and at the extremities of the distribution system. Testing for any parameters listed as Schedules 1, 2, and 3 of Ontario Regulation 169/03 are conducted at a certified contract laboratory as required by legislation. Certified laboratories must report all drinking water test results directly to the Ministry of the Environment, Conservation and Parks and to the Town of Greater Napanee, Infrastructure Services Department.
Alarms and Staffing
The A. L. Dafoe Water Treatment Plant is staffed 8 hours per day, 5 days per week. On weekends and holidays, staff visit the facility to conduct routine rounds and testing. During off- hours, process irregularities or building security breaches are detected by the plant alarm system and relayed to an on-call operator.

3 Flow Measurement and Analytical Testing
Raw and Treated Water Flow
Water supply to the Town of Napanee originates from either Lake Ontario or the Napanee River. Lake Ontario is the primary source while the alternate source (Napanee River) is reserved for emergency circumstances if transmission from the Lake were interrupted for an extended period of time. Permission to draw raw water from those sources is authorized by a Permit to Take Water issued by the Ministry of the Environment, Conservation and Parks. The current permit is valid until 2024 and allows a maximum taking of 12,000m3/d. The Permit to Take Water was not exceeded on any day in 2018. Flow meter accuracy is checked and verified annually by a certified technician.
Raw and treated water data collected during 2018 are presented in Table 1. During 2018, all raw water treated at the A.L. Dafoe Water Treatment Plant was pumped from the Lake Ontario source. The average and maximum day raw water flows were 4,430 m3/d and 6,777 m3/d respectively.

Treated water pumped from the A.L. Dafoe Water Treatment Plant to the Napanee community during 2018 averaged at 4,774 m3/d, which is approximately 21 percent more than the average day flow recorded for the previous year. Based on the 2018 average day flow, the plant is operating at approximately 46 percent of the design capacity. The maximum day flow recorded in July of 2018 3 represents approximately 81 percent of the design capacity of 10,450 m /d.
Trending of monthly average day treated water flows comparing data from 2017 and 2018 (Figure 4) indicates that water consumption has increased slightly.

Turbidity
Turbidity, a measure of the cloudiness of water due to suspended materials, is monitored daily in the raw water entering the plant and continuously in the effluent from each of the two water treatment plant filters. Measurement of raw water turbidity is necessary to monitor any changes to the raw water that may require adjustment of the treatment process. Filtered water is monitored to verify the particulate removal efficiency of the chemically assisted filtration process.
The maximum acceptable filter effluent turbidity, according to the Ontario Drinking Water Quality Standards (ODWQS), is 1 NTU. The treatment facility is equipped with process alarms that alert staff to abnormally high turbidity measurements well in advance of reaching that limit. In the event that the alarm set point is exceeded, the filter valves automatically close, halting the production of substandard water until the problem is addressed by operations staff.

Raw water turbidity values indicate a source water of generally good clarity, averaging 1.46 NTU and ranging from 0.31 NTU to 8.93 NTU.
The annual average filtered water turbidity measured at filters 1 and 2 were 0.042 NTU and 0.029 NTU respectively, indicating excellent treatment process performance. Filtered water turbidity did not exceed the drinking water standard at any time during 2018.
Operation of the continuous turbidity analyzers is checked by conducting periodic duplicate analysis using portable bench top instrumentation. All turbidity monitoring equipment is routinely cleaned and calibrated by staff.
Temperature, Colour, pH, and Alkalinity
Temperature, colour, pH, and alkalinity are measured in raw and treated water each week day and are summarized for 2018 in Table 3.

The data show that the raw water supply varies significantly in temperature over the course of the year. Raw water temperature ranged from 2.7oC to 21.9oC, while treated water ranged from 2.5oC to 23.4oC. Coagulants (such as alum, which is used in the A.L. Dafoe treatment process) do not act as quickly in colder water and therefore dosage adjustments may be required during winter months.
Colour develops in raw water sources from the decay of naturally occurring organic matter. The resulting colloidal and dissolved organic compounds react with coagulant chemicals and can increase dosage requirements. Colour removal is sometimes enhanced by pre-chlorination. During 2018, raw water colour measurement ranged from 4 apparent colour units (ACU) to 14 ACU, averaging 8 ACU. Effective removal was achieved through the process as the maximum colour in treated water samples in 2018 was 0 ACU.
Coagulants are most effective within specific ranges of pH. Alum performs best between pH 5.8 and pH 8.5. It is important to note that alum is an acidic solution which tends to lower the alkalinity and pH of process water. Both raw and treated water pH values were relatively stable throughout
Town of Greater Napanee
Infrastructure Services (Utilities) - Annual Compliance Reports Page 56 of 326 A.L. Dafoe (Napanee) Drinking Water System - 2018 Annual Report 22
the year, averaging 7.9 and 6.8 respectively.
Closely related to pH, alkalinity is a measurement of the acid buffering capacity of water. (The higher the alkalinity, the more acid that can be added before a change in pH occurs.) Several substances naturally present in raw water are measured as alkalinity, the majority of which are carbonate compounds. Coagulants, when added to water, combine with the alkalinity to produce insoluble metal hydroxides that play an important role in forming good floc. Alum, as mentioned above, is acidic and therefore decreases alkalinity. If too much natural alkalinity is consumed neutralizing the alum, there may be insufficient alkalinity remaining for optimal floc formation. Therefore, if a noticeable drop in pH (and alkalinity) is occurring, it may be necessary to lower the coagulant dosage to conserve alkalinity, or to add alkalinity to the incoming raw water. Raw and treated water alkalinities were relatively consistent through 2018 averaging 84 mg/L and 73 mg/L, respectively. All treated water alkalinity measurements were within the ODWQS recommended operational objective range of 30 – 500 mg/L.
Disinfection
Disinfection of the water supply protects public health by ensuring the inactivation of potentially harmful micro-organisms that may have passed through the treatment process or entered the distribution system by other means. A minimum free residual of 0.2 mg/L, maintained throughout the distribution system, is recommended by the Procedure for Disinfecting Drinking Water in Ontario. Less than 0.05 mg/L free residual is considered adverse and may pose a potential threat to public health. Additionally, the guideline requires that treated water must be mixed with the disinfectant and retained for a minimum period of time before distributing to customers. This is referred to as CT which is the product of the disinfectant concentration and the amount of time the water is exposed to the disinfectant. Research has demonstrated that CT is directly related to the rate of pathogen inactivation.
Chlorine residuals are monitored continuously in raw and treated water. The treated water residual analyzer is equipped with alarms that alert the operators to process abnormalities and will shut down the process to prevent improperly disinfected water from entering the distribution system.
Town of Greater Napanee
Infrastructure Services (Utilities) - Annual Compliance Reports Page 57 of 326 A.L. Dafoe (Napanee) Drinking Water System - 2018 Annual Report 23
Treated water free chlorine residual measured at the treatment facility averaged 1.77 mg/L in 2018, which is well above the guideline minimum value of 0.2 mg/L. It is important to note that chlorine residual typically declines in proportion to the distance from the point of application. Relatively high chlorine residuals are required leaving the plant in order to ensure that at least 0.2 mg/L is maintained throughout the distribution system. Disinfectant residuals are summarized in Tables 4, 5, and 6.
Chlorine residual measurements are conducted using portable bench top instrumentation on distribution system samples and periodically on plant treated water to provide verification of the continuous analyzer values. Calibrations of measurement instruments are routinely conducted by staff.
Bacteriological Testing
Bacteriological testing verifies the effectiveness of the disinfection process by monitoring the presence of indicator organisms in the water supply. The indicator tests include total coliforms (TC), Escherichia coliforms (E. coli), and heterotrophic plate count (HPC). The confirmed presence of any TC or E. coli in the water supply indicates insufficient disinfection and an increased risk to public health.
Bacteriological testing is conducted on samples collected each week from the raw water source, the treatment plant, and at several remote locations in the distribution system. A total of 52 raw water samples were taken from Lake Ontario for bacteriological testing in 2018. A total of 333 water samples were collected from the treatment plant and distribution system for bacteriological testing in 2018. All test results met the requirements of the Ontario Drinking Water Quality Standards. Tables 4, 5 and 6 summarize results of raw, treated and distribution system bacteriological testing.

Process Chemical Addition
Two chemicals, aluminum sulphate (alum) and sodium hypochlorite are essential additives to the A.L. Dafoe water treatment process. Alum is a commonly used water treatment coagulant that is necessary for the effective operation of the flocculation and sedimentation processes. Average monthly alum dosages at the A. L. Dafoe Water Treatment Plant remained consistent throughout 2018, ranging from a low of 30.7 mg/L to a maximum of 40.4 mg/L. The total volume of alum used during 2018 increased by 25 percent when compared to 2017.
Aluminum, a component of alum, is sometimes observed in elevated concentrations in treated water when high dosages of alum are applied. Although not identified in the ODWQS as a health risk, high aluminum residual in the distribution system may cause scaling on pipes, interfere with certain industrial processes, or form floc particles within the distribution system. The aluminum concentration was tested in samples of treated water on 250 days in 2018. All results were below the ODWQS operational guideline limit of 0.1 mg/L. The maximum aluminum concentration observed during 2018 was 0.056 mg/L while the average was 0.024 mg/L.

Sodium hypochlorite is added as a disinfectant to ensure that the treated water is free of active pathogens. Variations in chlorine dosages are typical throughout any given year. Dosage adjustments are made necessary by changes in water temperature, pH, flow rates, and distribution system residuals. Overall chlorine consumption is typically higher during summer months due to the seasonal increase in water demand. The volume of disinfectant used in 2018 was 19% higher than that used in 2017, which amounts to 6584 litres.

Chemical Testing
Analyses of over 70 additional organic and inorganic parameters in the treated water are required at various frequencies. The majority of those substances, listed as Schedules 23 and 24 in Ontario Regulation 170/03 must be tested at least annually. Testing for nitrite, nitrate, and trihalomethane compounds is required quarterly, while sodium and fluoride must be tested once every 5 years.
The results of those analyses are summarized in Tables 8, 9, 10 and 11. Concentrations of the majority of the substances were lower than the analytical method detection limits (either non-

Lead Testing The A.L. Dafoe (Napanee) Drinking Water System qualified for reduced sampling requirements, as measured lead concentrations observed in samples collected from residential plumbing do not pose a risk to public health based on current standards. In 2018, the municipal lead sampling program continued with distribution system testing conducted over two intervals; the first between December 15, 2017 and April 15, 2018 representing cold water conditions, and the second between June 15, 2018 and October 15, 2018 when water temperature is warmer. During each round, staff were required to sample 3 distribution system locations. All of the required samples were collected, and all were below the Ontario Drinking Water Quality Standards limit for lead. Lead concentrations observed in all of the samples collected in 2018 were well below the regulatory limit. Napanee continues to be exempt from any further residential plumbing sampling unless future distribution testing indicates a change in water chemistry or elevated lead concentrations.

Waste Residuals Treatment Process
The waste residuals treatment process is designed to thicken the waste generated from the water treatment process which includes alum sludge from the sedimentation process as well as filter backwash water. The thickened waste is discharged to the municipal sewer for further treatment at the Water Pollution Control Plant, while the treated supernatant (effluent) from the process flows to the Napanee River.
Suspended solids measured in the effluent from the process are not to exceed an annual average of 25 mg/L. Although composite sampling of the effluent is required once per week, the process is also equipped with continuous suspended solids monitoring instrumentation which will automatically shut down the process if the effluent limit is approached. This safeguard protects the Napanee River from accidental discharges of non-compliant effluent.
The residuals treatment process performed well in 2018 as effluent solids remained below the regulated limit. The annual average effluent total suspended solids concentration was 5.61 mg/L. It should be noted that the residuals treatment process was taken down for preventative maintenance for four months in 2018. During this maintenance period, all parts of the residuals process were sent directly to the Water Pollution Control Plant for treatment.
Effluent from the process is de-chlorinated if necessary, by the addition of sodium bisulphite. Chlorine was not detected in any of the effluent samples discharged to the Napanee River during 2018.

4 System Maintenance and Improvements
Maintenance and improvements at the Napanee facilities during 2018 included the following:
• The Densadeg (residuals treatment) Unit was spot repaired and recoated. The compartment tube settlers were also replaced.
• Distribution system fire hydrants were inspected, lubricated, and flow tested. The hydrant program serves as a preventive maintenance measure that identifies repair requirements and ensures reliability for community fire protection. Flushing also rids the distribution piping of accumulated sediments.
• The Town of Greater Napanee continued to work closely with Quinte Conservation and Cataraqui Region Conservation Authority regarding the approved Source Water Protection Plans and Education and Outreach programs.
• Necessary watermain replacement and upgrades were completed on Dundas Street East. The existing 250mm cast iron main was replaced with a more durable polyvinyl chloride (PVC) watermain. The limits of replacement included approximately 320 meters from the Centre Street intersection Easterly to just West of Adelphi Street. This project also included the replacement of water services and curb stops on municipal properties.
• Approximately 320m of new 300mm PVC watermain was installed along Circuit Ryder Drive, along with two 1500mm water services. This extension will service future commercial development lands.
• As part of the West Bridge Estates, South Phase VI development, 544m of 300mm PVC watermain, plus hydrants and appurtenances were installed on McLaren Drive and Briarwood Crescent. In addition, Street A received 193m of 200mm PVC watermain, plus hydrants and appurtenances. The subdivision was connected to existing watermain at the Cherrywood Parkway and Highway 2 intersection which provides beneficial water looping.
• 175 residential water meters were replaced within the distribution system as part of the 20-year replacement program. This program enhances accuracy in water usage monitoring and aids in eliminating water loss within the distribution system.

Cryptosporidium are a group of protozoa (single celled organisms) that are parasitic in the intestines of humans and most other animals, and are capable of causing diarrhoea.
Designated Facility refers to facilities that serve vulnerable populations such as children and the elderly. These facilities include children’s camps, child and youth care facilities, health care and social care facilities, schools, universities, and colleges.
Escherichia Coli (E. Coli) refers to a subgroup of fecal coliform bacteria that reside in the digestive systems of warm blooded animals. The presence of E. Coli in drinking water is a strong indicator of fecal contamination. E. Coli is rapidly destroyed by chlorine.
Giardia are a group of protozoa (single celled organisms) that are parasitic in the intestines of humans and most other animals, and are capable of causing diarrhoea.
Heterotrophic Plate Count (HPC) is a microbial test method that quantifies levels of heterotrophic bacteria. Most bacteria, including many of those common in drinking water systems, are heterotrophs. Within a distribution system, increases in the density of HPC bacteria are usually the result of bacterial re-growth which is influenced by the quality of the water entering the system, temperature, flow conditions (i.e. stagnation), presence of a disinfectant residual, construction materials, and the availability of nutrients for growth. HPC in drinking water are not considered a direct health threat to the general public.

Introduction
The 2018 Annual Drinking Water Report for the North Fredericksburgh Community Centre (North Fred) Drinking Water System summarizes treatment system operations and treated water quality with reference to the requirements of Ontario Regulation 170/03 (O. Reg. 170/03).
On December 1, 2008, oversight of small drinking water systems was transferred from the Ministry of the Environment to the Ministry of Health and Long-Term Care under the Health Protection and Promotion Act. The North Fred Drinking Water System is classified as a small municipal non-residential system, and therefore would not normally be subject to the requirements of O.Reg.170/03, except that Lennox and Addington Resources for Children (LARC) has operated a child care facility within the building. Child care facilities are considered designated facilities and the drinking water systems supplying them must comply with O.Reg.170/03, regardless of the size of the system. It should be noted that the child care facility is not currently operating at the site. Since the future of the Community Centre is unknown, the department is continuing to monitor the site as though it is still in use under its previous conditions.
Description of the Treatment Process
Raw Water Supply
Source water is supplied to the North Fred Drinking Water System from the raw water main that is used to supply the A.L. Dafoe Purification Plant in Napanee. Two pumps located at the Lake Ontario Pumping Station (County Road #21 and Highway #33) are used to transfer raw water through a 500 mm diameter water main, 16 km along County Road #8 from Lake Ontario to the A.L. Dafoe Purification Plant raw water reservoir.
The water drawn from Lake Ontario is chlorinated at the Lake Ontario Pumping Station to prevent biological growth within the raw water pipeline, to provide initial disinfection, and to control the growth of Zebra Mussels at the lake intake.

Infrastructure Services (Utilities) - Annual Compliance Reports Page 72 of 326 North Fredericksburgh Community Centre Drinking Water System – 2018 Annual Report 2
Filtration
The North Fred Drinking Water System uses a series of three different types of filters to achieve effective levels of filtration (see Figure 1 below). Raw water entering the drinking water system first passes through a sand filter to physically remove suspended particles and thereby reduce turbidity. The sand filter backwashes automatically, once each day. Second, the water passes through an activated carbon filter which removes the chlorine that was added at the Lake Ontario Pumping Station, along with any other tastes or odours that may be present. Third, the water passes through a series of cartridge filters that successively decrease in pore size. The cartridge filters are installed in parallel series of three filters each (see Figure 1) and are capable of removing most of the Giardia and Cryptosporidium cysts that may be present in the water. The cartridge filters are not NSF-certified and therefore cannot obtain official MOECC Giardia and Cryptosporidium removal credits. Disinfection is achieved by the UV system.
Disinfection
Filtered water in the North Fredericksburgh Drinking Water System is disinfected by twin parallel ultraviolet light (UV) systems (Figure 1). UV radiation effectively disinfects drinking water by penetrating the cell walls of any organisms that are present and disrupting the ability of the organisms to reproduce.

No secondary disinfection is required since the treated water is distributed only within the building that houses the treatment system itself.

Declaration of Professional Engineer
A Professional Engineer has declared in writing that the North Fredericksburgh Drinking Water System provides all equipment required to ensure compliance with all applicable provisions of Ontario Regulation 170/03. The Engineering Evaluation Report was prepared by Totten Sims Hubicki Associates (now AECOM) in March of 2004.
Laboratory Testing
Ontario Regulation 170/03 dictates the sampling and monitoring requirements for the North Fredericksburgh Drinking Water System. Testing for any parameters listed as Schedules 1, 2, and 3 of Ontario Regulation 169/03 are conducted at a certified laboratory as required by legislation.
Alarms and Staffing
Each of the UV disinfection systems is equipped with a solenoid valve which shuts off the supply of water to the building if an alarm is triggered. The system contains visual and audible notification if the lamp output is low or the system stops working.
Staff inspects the North Fredericksburgh Drinking Water System at least once each week.
Reporting of Adverse Water and Other Deficiencies
During 2018, there were no indications of adverse water quality based on the testing of treated water samples.
Analytical Testing
Turbidity
Turbidity is measured typically once each week, in both the raw water entering the treatment system and in the effluent from the filters. Although the regulations do not require turbidity

Infrastructure Services (Utilities) - Annual Compliance Reports Page 74 of 326 North Fredericksburgh Community Centre Drinking Water System – 2018 Annual Report 4
measurement at small municipal non-residential systems, at North Fredericksburgh, the Utilities staff conduct the testing to verify the treatment process performance. The Ontario Drinking Water Quality Standards (ODWQS) maximum acceptable turbidity applicable to municipal filtered water is 1 NTU. Treated water turbidity did not exceed the standard of 1 NTU during 2018 (Figure 2).

Bacteriological Testing
Bacteriological testing measures the effectiveness of the disinfection process by monitoring the presence of indicator organisms in the water supply. The indicator tests include total coliforms (TC), Escherichia coli (E. coli), and heterotrophic plate count (HPC). The presence of any TC or E. coli in the water supply indicates insufficient disinfection and that the water may pose a health hazard if consumed.
Samples were collected by staff at a minimum of once per month to evaluate the bacteriological quality of pre-chlorinated raw water entering the North Fredericksburgh Drinking Water System from the Lake Ontario Pumping Station.
Treated water is tested for bacteriological quality once per week, which exceeds the monthly sampling that is required by the regulation. Analytical results from samples collected during 2018 indicated that the drinking water met the bacteriological requirements of the ODWQS, which are summarized in Table 2, below.

Executive Summary
The Sandhurst Shores Water Treatment Plant is a chemically assisted filtration plant that services approximately 99 homes. Reliability of the small municipal residential drinking water system is enhanced by continuous monitoring instrumentation, process alarms, and critical equipment redundancy.
During 2018, the total volume of treated water provided to the community increased by 14% when compared to the volume used during 2017. Significant capacity for treated water remains available to the community as the maximum day flow recorded during 2018 represented approximately 41 percent of the plant design capacity. On an average day during 2018, the community used approximately 16 percent of the plant capacity.
Water samples collected throughout the process at varying frequencies were tested for approximately 70 different parameters to evaluate treatment efficiency and to ensure finished water quality. Target parameters range from critical indicators related to potential acute health effects, to non-health related parameters that aid in assessing process efficiency or the aesthetic quality of the drinking water. All sample analyses during 2018 met the stringent requirements of the Ontario Drinking Water Quality Standards.
The continual provision of safe and reliable municipal water supply requires diligent upkeep and timely replacement of existing equipment, as well as ongoing efforts to improve efficiency and system reliability. Routine preventive maintenance practices were consistently applied throughout 2018 at the Sandhurst Shores Water Treatment Plant.

Raw Water is defined as surface (lakes, rivers) or ground water (wells) available as a source of drinking water that has not received any treatment. Sedimentation refers to the water treatment process that involves reducing the velocity of process water to allow gravity settling of suspended material within relatively large (sedimentation) tanks. Total Coliform Bacteria are a group of commonly occurring, mostly harmless bacteria that live in soil and water as well as the gut of animals. Their presence in a water sample may be indicative of inadequate filtration and/or inadequate disinfection. Turbidity refers to a physical characteristic of water that causes a cloudy appearance. Turbidity is caused by the presence of suspended matter. The substances that cause turbidity may be a source of disease causing organisms, and can shield potentially pathogenic organisms from disinfection.

1 Description of the Treatment Process
Raw Water Supply
Raw water enters the treatment plant through a 250 mm diameter intake pipe which extends approximately 250 m into Lake Ontario and is submerged to a depth of about 12 m. Screens at the plant inlet prevent any large debris from passing into the treatment process. After screening, raw water flows into a tank referred to as a low lift well from where it is pumped to the treatment process. The low lift pumps are controlled by the volume of treated water stored at the plant. As community use lowers the level of the treated water storage tanks, the low lift pumps are activated to replenish the used volume.
Package Plant Treatment Unit
The Sandhurst Shores treatment process combines coagulation, flocculation, sedimentation, and filtration in one large partitioned steel tank (Figure 1). This integrated process design, which is common in smaller communities, is referred to as a package plant. Within the package plant, raw water first enters a vertical cylinder known as a draft tube. The draft tube contains a turbine that creates a rapid mixing zone where coagulation is induced by the addition of alum and polymer. As the coagulating chemicals mix with the water, flocculation (gathering together) of suspended particles occurs. As flow progresses downstream from the draft tube, velocity decreases within the flocculation zone where baffles gently mix the flocculated solids causing them to collide and join together to form larger clumps prior to entering the settling compartment.
The settling compartment contains a series of inclined hollow 50mm plastic tubes. The inclined tubes are designed to maximize the rate at which flocculated solids settle to the bottom of the tank. The accumulated settled solids are periodically drained from the bottom of the settling compartment to a waste holding tank. The relatively clear water at the top of the settling compartment flows into the dual media (sand and anthracite) filters. The filters remove particulate matter that may remain in suspension following the settling compartment. The filters require regular cleaning which is accomplished by a process referred to as backwashing.
Town of Greater Napanee - Utilities
Infrastructure Services (Utilities) - Annual Compliance Reports Page 88 of 326 Sandhurst Shores Drinking Water System - 2018 Annual Report 3
Backwashing temporarily reverses flow through the filter and discharges the wash water to a waste holding tank.
Clearwell Storage and Distribution
Treated water is stored in a 475 m3 reservoir, commonly referred to as a clearwell, located below the package plant. Water from the clearwell is pumped to the distribution system using one of three high lift pumps (1 duty and 2 standbys). Constant distribution system pressure is maintained by a variable speed pump controller and two large pressure tanks.
Waste Residuals Treatment
Waste residuals generated through the treatment process, which includes settling compartment solids and filter backwash water, are discharged from the package plant to a waste holding tank. The thickened, settled material at the bottom of the waste holding tank is withdrawn and hauled to the Napanee Water Pollution Control Plant for further treatment. The relatively clear top treated portion of the waste tank volume is pumped to an exfiltration pit located west of the treatment plant building. The exfiltration pit contains a large volume of granular material that allows the treated water to gradually seep into the surrounding soil.

Disinfection and Zebra Mussel Control
The Sandhurst Shores water supply is dosed with chlorine at two points; one for pre-chlorination / Zebra Mussel control upstream from the package treatment process, and the other for post- chlorination immediately following the package treatment process.
Pre-chlorination is applied at the opening of the Lake Ontario intake pipe. Although marginally useful for initial disinfection, the primary role of pre-chlorination is to control nuisance biological growth and Zebra Mussel infestation within the raw water intake pipe.
Disinfection of treated water (post-chlorination) occurs as the filtered water enters the clearwell. Post- chlorination is a critical and final disinfection step prior to distributing the water to the community. Post-chlorination dosing is adjusted to optimize the inactivation of potentially harmful bacteria, and to ensure that a sufficient concentration of chlorine persists throughout the distribution system. Distribution system chlorine residual prevents biological growth at the farthest reaches of the system.
Treatment Chemicals
Three chemicals; sodium hypochlorite, aluminum sulfate (alum), and polymer are used in the Sandhurst Shores water treatment process.
Sodium hypochlorite contains approximately 12 percent chlorine and is added to the system to control biological growth and ultimately to inactivate pathogens that may be present in the raw water. The sodium hypochlorite solution meets the requirements of the Canadian General Standards Board and American Water Works Association (AWWA) B-300-10 for use in drinking water.
Aluminum sulfate, also known as liquid alum, is used as the primary coagulant in the treatment process. The liquid alum meets AWWA Standard B-403-16 and is approved by the National Sanitation Foundation (NSF), for use in drinking water to a maximum dosage of 150 mg/L.
The anionic polymer used in the water treatment process acts as a flocculant aid. It is supplied in powder form which is mixed with water at the plant and added to the process as a solution. The polymer is approved by NSF for use in drinking water treatment processes to a maximum dose of 1 mg/L.

Origins and Types of Contaminants
As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and can pick up substances resulting from human activity or the presence of animals.
The types of contaminants that may be present in source water include:
• Microbiological contaminants that may come from septic systems, livestock, sewage treatment plants, and wildlife. Microbiological quality is a critical component of drinking water quality because of its ability to cause acute illness in consumers.
• Inorganic contaminants, such as salts and metals, which can be naturally occurring or may result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
• Organic contaminants can be naturally occurring, but most of the compounds of concern are man- made. Pesticides and herbicides are included in this group and may originate from a variety of sources such as agriculture, storm water runoff, and septic systems.
Multiple Barriers to Microbiological Pathogens
Potentially pathogenic organisms are removed from the raw water source by the following processes: • pre-chlorination • flocculation / sedimentation • filtration • post-chlorination • distribution system chlorine residual
Laboratory Testing
Ontario Regulation170/03 and the Municipal Drinking Water License issued for the plant dictate the sampling and monitoring requirements for the Sandhurst Shores Drinking Water System. Water quality is tested routinely throughout the treatment process and at the extremities of the distribution system. Testing for any parameters listed as Schedules 1, 2, and 3 of Ontario Regulation 169/03 are conducted at a certified contract laboratory as required by legislation.
Town of Greater Napanee - Utilities
Infrastructure Services (Utilities) - Annual Compliance Reports Page 92 of 326 Sandhurst Shores Drinking Water System - 2018 Annual Report 7
Alarms and Staffing
The Sandhurst Shores Water Treatment Plant is visited by a licensed operator 7 days per week to perform equipment and process inspections, maintenance, routine lab testing, data collection and review. When the plant is unattended, process irregularities or building security breaches are detected by the plant alarm system and relayed to an on-call operator who is available 24 hours per day, 7 days per week.
2 Reporting of Adverse Water and Other Deficiencies
All samples collected and tested in accordance with O.Reg.170/03 met the requirements of the Ontario Drinking Water Quality Standards. Disinfection of treated water was maintained consistently as prescribed in the MOECC publication, Procedure for Disinfecting Drinking Water in Ontario. No corrective actions, as detailed in O.Reg.170/03, Schedule 18, were required.
Water quality data and disinfectant residuals are provided in summary tables throughout Section 3 of this report.
3 Flow Measurement and Analytical Testing
Raw and Treated Water Flow
Raw water is pumped from Lake Ontario in accordance with the terms and conditions stated in a Permit to Take Water (PTTW) issued by the Ministry of the Environment, Conservation and Parks. The PTTW allows a maximum withdrawal from the lake of 600 cubic meters per day (m3/d) and was not exceeded at any time during 2018. The Sandhurst Shores Water Treatment Plant is licenced to discharge a maximum flow of 372 m3/d into the distribution system. During 2018 the average flow into the distribution system was 60 m3/d while the maximum day flow was 152 m3/d. The maximum day flow represents approximately 41 percent of the plant capacity. The total volume of treated water provided to the Sandhurst Shores community during 2018 was increased by 14% when compared to 2017. Table 1 provides a summary of raw and treated water flows.

Temperature, Colour, Alkalinity, and pH
Temperature, colour, alkalinity, and pH are monitored in raw and treated water throughout each week. Measurements recorded during 2018 are summarized in Table 2.
The data shows that the Sandhurst Shores Water Treatment Plant treats a raw water supply which varies significantly in temperature over the course of the year. Raw water temperature recorded daily
Town of Greater Napanee - Utilities
Infrastructure Services (Utilities) - Annual Compliance Reports Page 94 of 326 Sandhurst Shores Drinking Water System - 2018 Annual Report 9
ranged from 0.0oC to 18.8oC, while treated water temperature ranged from 1.8oC to 18.0oC. Coagulants do not act as quickly in colder water and therefore higher dosages may be required during winter months.
Colour develops in raw water sources primarily from the decay of naturally occurring aquatic plants. The resulting colloidal and dissolved organic compounds react with coagulant chemicals and can increase dosage requirements. Colour removal can be enhanced by oxidation which occurs during pre- chlorination. In 2018, raw water colour ranged from 0 ACU to a maximum of 32 ACU. Effective removal was achieved through the treatment process as the maximum colour result on a treated water sample was 13 ACU.
Coagulants are most effective within specific ranges of pH. For example, alum performs best between pH 5.8 and pH 8.5. It is important to note that alum is an acidic solution which tends to lower the alkalinity and pH of process water. The raw and treated water average pH values measured during 2018 were 7.5 and 7.0 respectively.
Closely related to pH, alkalinity is a measurement of the acid buffering capacity of water. (The higher the alkalinity, the more acid that can be added before a change in pH occurs.) Several substances naturally present in raw water are measured as alkalinity, the majority of which are carbonate compounds. Coagulants, when added to water, combine with the alkalinity to produce insoluble metal hydroxides that play an important role in flocculation. Alum, as mentioned above, is acidic and therefore decreases alkalinity. If too much natural alkalinity is consumed by the alum, there may be insufficient alkalinity for optimal floc formation. Therefore, if a noticeable drop in pH (and alkalinity) is occurring, it may be necessary to lower the coagulant dosage to conserve alkalinity or alter the process by adding alkalinity to the incoming raw water.
During 2018, raw and treated water alkalinities were consistently within the range recommended in
the ODWS, Objectives and Guidelines, averaging 84 mg/L and 77 mg/L as CaCO3, respectively.

Turbidity
Effective operation of the treatment processes is verified by continuous monitoring of filter effluent turbidity. In the event of a significant upward trend in filtered water turbidity, an alarm is triggered to notify staff of a process abnormality. If turbidity continues to rise above the alarm limit, a second limit (typically set to half of the compliance limit) will trigger an interlock switch that automatically shuts down the treatment process until the cause is investigated and corrected. The regulation requires that filtered water turbidity must not exceed 1 NTU and that each month at least 95 percent of values are less than or equal to 0.3 NTU.
Table 3 is a summary of raw, filtered, and treated water turbidity measured during 2018. The summary is based on continuous measurement of filtered water and from measurements of raw and treated samples taken at least twice weekly using a portable bench top turbidity meter. The turbidity analyzers are routinely maintained and calibrated by Utilities staff.
During 2018 the treatment process consistently complied with the regulatory limit for turbidity, averaging 0.023 NTU.

Raw and treated water turbidity is measured throughout each week to monitor raw water quality trends and to ensure that treated water meets the ODWQS aesthetic objective. Raw water values reflected good source water clarity ranging from 0.09 NTU to 3.93 NTU. Treated water turbidity was consistently below the aesthetic objective of 5 NTU, averaging 0.15 NTU.
Disinfection and Bacteriological Testing
Tables 4, 5 and 6 summarize raw, treated, and distribution system disinfectant residuals as well as bacteriological testing results. Chlorine residuals are continuously monitored in pre-chlorinated raw water entering the plant, in treated water leaving the plant, and at one location in the distribution system. Sufficient chlorine must be added to the treated water to satisfy disinfectant contact time requirements (CT), and to maintain a free residual of at least 0.05 mg/L at all locations in the distribution system. The operational guideline (non-health related) maximum concentration for chlorine at any point in the distribution system is 4 mg/L measured as free chlorine, and 3 mg/L measured as combined chlorine.
During 2018, treated water free chlorine residual measured at the treatment plant averaged 1.74 mg/L while the free residual in the distribution system averaged 1.52 mg/L. Disinfection CT, as defined by

Chemical Testing
Analyses of over 60 additional organic and inorganic chemical parameters in the treated water are conducted at various frequencies. The majority of those substances, listed as Schedules 23 and 24 in Ontario Regulation 170/03 as well as sodium and fluoride, must be tested at least once every 5 years. Nitrite, Nitrate, and THMs are tested quarterly.
The results of those analyses are summarized in Tables 8, 9, 10, 11 and 12. Concentrations of over 80 percent of the substances were lower than the analytical method detection limits (either non-existent or in trace levels too low to measure), while the measured concentrations of the remaining substances were below the maximum acceptable concentrations listed in the ODWQS.

Lead Testing
The Sandhurst Shores Drinking Water System qualified for reduced sampling requirements, as measured lead concentrations observed in samples collected from residential plumbing do not pose a risk to public health based on current standards. In 2018, the municipal lead sampling program continued with distribution system testing conducted over two intervals; the first between December 15, 2017 and April 15, 2018 representing cold water conditions, and the second between June 15, 2018 and October 15, 2018 when water temperature was warmer. During each round, staff were required to sample one distribution system location. All of the required samples were collected, and all were below the Ontario Drinking Water Quality Standards limit for lead. Lead concentrations observed in all the samples collected in 2018 were well below the regulatory limit. The Sandhurst Shores Drinking Water System continues to be exempt from any further residential plumbing sampling unless future distribution testing indicates a change in water chemistry or elevated lead concentrations.

Executive Summary The quality of effluent released to the Napanee River from the Napanee Water Pollution Control Plant (WPCP) during 2018 complied with the limits stipulated in the plant Environmental Compliance Approval (ECA). The effluent bacteriological quality measured as E. Coli. also met the ECA operational objective (<200 CFU/100mL) in all months except for August 2018 when the monthly geometric mean was 781 CFU/100mL.
Total annual flow measured in 2018 decreased by approximately 7.9 percent when compared to the previous year, with the average day flow representing 84 percent of the plant design capacity. Efforts to detect the inflow and infiltration of storm and ground water sources will continue throughout 2019.
Biosolids generated at the facility were temporarily stored at the Sutcliffe Lagoon and were applied to agricultural land during June and November by Terratec Environmental, all in accordance with the sites Certificates of Approval and Ontario Regulation 267/03.
Maintenance and upgrading activities during 2018 included Phase 1 upgrades to the WPCP which included new digester biogas piping, a new flare stack and the installation of a standby natural gas fired boiler. A new bar screen was fabricated and installed in the headworks building. In addition to these projects, the sanitary sewer main on a large portion of Dundas Street East was replaced which included sanitary services to individual property lines.
An Environmental Assessment to evaluate treatment capacity needs over the next 20 years was conducted throughout 2010 and concluded in early 2011. The study recommended a 25% expansion in average day flow capacity and approximate doubling of peak flow capacity. The recommended upgrades can be accommodated on the existing site using readily available treatment technologies; however, a phased approach is desired for several reasons.

1 Wastewater Flows and Effluent Quality Wastewater Flow Data
The Napanee Water Pollution Control Plant (WPCP) is a conventional activated sludge process, with an average day design flow rate of 9087 m3/d, and a peak flow rate of 21,370 m3/d. The average flow during 2018 was 7660 m3/d, which is approximately 84 percent of the design capacity. Non-compliance with respect to treatment capacity is defined in the Environmental Compliance Approval as:
“…the introduction of sewage flows in excess of the average daily flow (9087 m3/d) for any consecutive period of time greater than one year.”
The plant design capacity of 9087 m3/d was exceeded on 82 days in 2018 which was decreased when compared to the 126 days experienced in 2017. WPCP flow data collected during 2018 is presented in Table 1.
The hydraulic capacity of the plant continues to be stressed as a result of high flow experienced during heavy precipitation events or during periods of rapid ice and snow melting. The maximum daily flow during 2018 was 20,423 m3/d. Although the Town of Napanee has a separate storm water collection system; improper connections, broken pipes, or faulty joints in sanitary sewers can result in the introduction of ground and storm water into the sanitary collection system. This misdirected hydraulic load on the sanitary system is collectively referred to as inflow and infiltration. Inflow and infiltration is problematic because it occupies treatment capacity that could otherwise be used to treat sanitary wastewater.

Dry weather flow, typically experienced during summer months (July, August) is an approximate representation of sanitary wastewater flows exclusive of the effects of inflow and infiltration. Minimum daily flow rates recorded during those months indicate that dry weather flow accounts for 44 percent of the of the average day design capacity. The 2018 average day flow was 84 percent of the design capacity, down from the 91 percent in 2017. Inflow and infiltration continue to be problematic and repairs to all identified issues will continue to be ongoing throughout 2019.

Efforts to identify and control sources of inflow and infiltration have included the following: ▪ Greater Napanee Utilities retained a consultant in early 2012 to conduct an inflow and infiltration study. Using this study collection, system deficiencies were corrected in 2013 and 2014. ▪ Flow meters are installed at six of seven sewage lift stations to determine areas of the collection system most impacted by inflow and infiltration. ▪ Restoration work has been conducted on manhole joints, connections, and benching as problem areas are identified. ▪ Covers (dishes) have been installed under the lids of manholes to prevent surface water from entering through holes in the manhole lids. ▪ Local construction specifications require that new manhole installations include rubber seals. ▪ A municipal bylaw prohibits the connection of sump pumps and rain leaders to the sanitary sewer. Staff have had great success in removing existing connections through education and outreach, with 61% of known connections disconnected since 2016.
Commencing in 2009 and continuing through 2010, an engineering study (Schedule C Municipal Class Environmental Assessment) was conducted to assess capacity limitations and to plan for the upgrade and/or expansion of the facility over a 20-year design horizon. The Environmental
Town of Greater Napanee - Utilities
Infrastructure Services (Utilities) - Annual Compliance Reports Page 111 of 326 2018 Annual Report – Napanee Water Pollution Control Plant 4
Study Report was completed in February 2011 and concluded that an additional 25 percent average day flow capacity and approximate doubling of peak capacity is required to meet future needs. The required upgrades can be completed on the existing site using readily available treatment technology and may be part of a phased approach.
In the interim, efforts to reduce inflow and infiltration continue. Any reductions achieved will be factored into down-sizing the design of the proposed facility.
Primary Bypass / Sewage Spills / Lift Station Bypass
Under all but the most extreme conditions, wastewater entering the plant undergoes preliminary treatment (screening and grit removal), primary treatment (gravity separation of solids by sedimentation), and disinfection. In the event that the influent flow rate exceeds 38,000 m3/d, the excess will bypass the primary clarifiers, mixing with the primary clarifier effluent prior to flowing toward the aeration basins. Bypassing of the primary clarifiers did not occur in 2018.
The discharge of untreated sanitary sewage from the collection system can occur at any of the seven sewage lift stations and/or collection system manholes as the result of flooding events, power outages, pump failures, or sewer blockages. Measures are in place to prevent bypassing/spills which include: multiple (backup) pumps at all lift stations, high level alarms, backup power generation capability, and readily available vacuum truck service.
Secondary Bypass
If the flow of wastewater directed to the aeration basins exceeds approximately 16,000 m3/d, the excess will pass over a flat weir (located immediately upstream from the aeration tanks), bypassing the secondary treatment process. Secondary bypassing limits the hydraulic loading on the secondary treatment process (aeration tanks and secondary clarifiers) to prevent washout of activated sludge which is essential for maintaining treatment process performance. Wastewater that bypasses the secondary process (which tends to be weak in strength due to dilution from inflow and infiltration) is blended with the ~16,000 m3/d of secondary clarifier effluent, prior to disinfection and is discharged to the Napanee River.

Infrastructure Services (Utilities) - Annual Compliance Reports Page 112 of 326 2018 Annual Report – Napanee Water Pollution Control Plant 5
The volume of secondary bypass discharges during 2018 was 26% less than the volume observed in 2017. This decreased volume is directly linked to the decrease in annual precipitation experienced in 2018. A summary of the secondary bypass events during 2018 is provided in Table 2.

*Ministry policy defines a bypass event as an occurrence separated by a period of more than 12 hours from another occurrence. When a bypass stops, it is considered to be the end of the event. If, however, a bypass begins again within 12 hours, it is considered to be the same event.
The relationship between precipitation and secondary bypass volume is illustrated in Figure 2. There appears to be a greater gap between total precipitation and secondary bypass volume in more recent years, suggesting that the ongoing efforts to prevent inflow and infiltration may be effective. Staff will continue to follow trends as more inflow and infiltration issues in the wastewater collection system are addressed.

BOD5 and Total Suspended Solids Analytical Data
The removal of biochemical oxygen demand (BOD5) and suspended solids from municipal wastewater is the primary design function of the Napanee WPCP, which utilizes a conventional activated sludge process. The principal mechanisms of removal include screening,
sedimentation, and biodegradation. BOD5 and suspended solids data collected during 2018 are summarized in Table 3.
Raw sewage entering the treatment process during 2018 was of moderate strength, having BOD5 and total suspended solids concentrations averaging 123.5 mg/L and 149 mg/L respectively. The pollutant removal efficiency of the plant is typical of the conventional activated sludge process
with BOD5 and total suspended solids removals averaging 93.1 and 95.5 percent. Annual average
effluent concentrations and mass loadings of both BOD5 and total suspended solids were well below the compliance limits of 25 mg/L and 227 kg/d.

Phosphorus and Nitrogen Analytical Data
Phosphorus is a nutrient that is essential to biological growth. It is typically present in raw sewage at concentrations sufficient to cause excessive plant and algae growth in natural surface waters if released untreated. Excessive growth in surface water deteriorates the aquatic environment when the plants / algae decompose.
Phosphorus is removed from sewage at the WPCP by the addition of ferric sulfate which forms an insoluble precipitate when it combines with phosphorus in the wastewater. The precipitate is then removed by sedimentation. Ferric sulfate is added to the process immediately downstream from the pre-treatment process but can also be added at the aeration tank influent channel, or at the tail end of the aeration tanks.
The annual average concentration of phosphorus in the raw sewage was 3.71 mg/L, while the average effluent concentration was 0.14 mg/L. Effluent quality consistently met the Environmental Compliance Approval Limit of 1.0 mg/L throughout 2018.

Total Kjeldahl Nitrogen (TKN) represents the total quantity of organically bound nitrogen plus ammonia nitrogen which are the forms that most commonly occur in raw sewage. Nitrogen removal (or conversion to less harmful nitrites and nitrates) occurs in the wastewater treatment process by the action of microorganisms in the secondary treatment process. Removal or conversion of the nitrogen species is important because if released in the form of un-ionized ammonia, it can be toxic to aquatic organisms.
In 2018, the annual average concentration of un-ionized ammonia in the process effluent was 0.06 µg/L, which is under the Provincial Water Quality Objective concentration of 20 µg/L.
Analytical data for phosphorus, nitrogen, pH, temperature, and alkalinity are summarized in Tables 4 and 5.

Disinfection / Bacteriological Testing
Prior to discharge to the Napanee River, the treated effluent is dosed with a disinfectant (chlorine) to inactivate any potential pathogenic organisms that may remain. Bacteriological testing is conducted each week to evaluate the effectiveness of the disinfection process. Grab samples for bacteriological testing (E. Coli.) were collected immediately downstream from the chlorine contact chamber, normally during peak flow conditions (between 8am and 10am) when the treatment process is typically most heavily burdened.
During 2018, all but one of the monthly geometric mean1 values calculated from weekly analyses were below the operational objective of 200 CFU/100mL. The geometric mean value for all samples collected during 2018 was 103 CFU/100mL.
In response to the Federal regulation requiring the elimination of total chlorine residual from municipal wastewater treatment plant effluents, de-chlorination using sulfur dioxide was introduced at the Napanee facility in late January 2010. Total chlorine residual concentration in

2 Maintenance / Improvements & Plant Upsets
Maintenance / Improvements
Maintenance activities and process improvements during 2018 included the following:
▪ Phase 1 upgrades to the facility include upgrades to the digester biogas system. This project included the demolition of portions of the existing digester biogas piping and flare stack. New biogas piping was installed, as was a new flare stack and associated mechanical and electrical equipment, which brought the facility into compliance with CSA B149.6–15 and TSSA-DLB-2016. These upgrades also involved the installation of a standby 1.5 million BTU natural gas fired boiler.
Town of Greater Napanee - Utilities
Infrastructure Services (Utilities) - Annual Compliance Reports Page 118 of 326 2018 Annual Report – Napanee Water Pollution Control Plant 11
▪ A new bar screen on the headworks unit was fabricated and installed.
▪ Efforts to detect and reduce inflow and infiltration are ongoing.
▪ The 2012 Inflow and Infiltration Study identified several key areas of concern that require rehabilitation or renewal. This document has become an integral part of our 10-year capital planning process. A considerable amount of infrastructure renewal will occur between 2014 and 2019. These targeted areas contain infrastructure that has been in service for > 100 years and was identified in the study as the area with the highest I&I rate.
▪ The sanitary sewer main was replaced on Dundas Street East. The limits of the replacement included approximately 320 meters from the Centre Street intersection Easterly to just West of the Adelphi Street intersection and included sanitary services up to individual property lines.
Process Upsets
During 2018 there were no observed significant upsets to plant performance other than the decreased level of treatment experienced during high flow events when heavy precipitation or melting is occurring. Although inflow and infiltration continues to be problematic, efforts to regain hydraulic capacity by monitoring, repairing, and maintaining the collection system are ongoing and appear to be effective.
3 Biosolids Biosolids Quality and WPCP Output (Lagoon Input) Volumes
Accumulated solids (sludge), removed from the municipal wastewater through the treatment process are stabilized in the anaerobic digestion process. The digestion process reduces the quantity of solids requiring disposal by converting the volatile fraction to methane gas. The methane gas is then beneficially used in the plant boiler for process and building heat.
Following the digestion process, the resulting stabilized sludge (referred to as biosolids) is hauled to an off-site storage lagoon owned and operated by Mr. Fred Sutcliffe Jr. (Provisional

Dear: Kristie
Re: A.L. Dafoe DWS 2018-2019 Inspection Report # 1-I96EV
The enclosed report documents findings of the inspection that was performed at the A. L. Dafoe drinking water system on December 10, 2018.
Two sections of the report, namely “Non-compliance with Regulatory Requirements and Actions Required” and “Summary of Recommendations and Best Practice Issues”, if found, will cite due dates for the submission of information or plans to my attention.
Please note that “Non-compliance with Regulatory Requirements and Actions Required” are linked to incidents of non-compliance with regulatory requirements contained within an Act, a Regulation, or site-specific approvals, licenses, permits, orders, or instructions.

COMPONENTS DESCRIPTION ______Site (Name): MOE DWS Mapping Type: DWS Mapping Point Sub Type: ______
Site (Name): RAW WATER Type: Source Sub Type: Surface Water Comments: WATER SOURCE The treatment plant is equipped to draw water from the Napanee River, however, its primary water source is Lake Ontario.
The Lake Ontario raw water pumping station is located southeast of the intersection of Highway 33 and Lennox & Addington County Road No. 21; directly across Highway 33 from Ontario Power Generation's Lennox Thermal Generating Station. The station consists of an intake pipe, low lift pumping station and approximately 14.8 km of 500 mm diameter water main along County Road #8 to a raw water reservoir.
The Lake Ontario intake facilities incorporates a 300 mm diameter intake pipe extending 53 metres lakeward into Adolphus Reach (Lake Ontario), complete with a protective intake crib, having a firm capacity of 10,450 cubic metres per day with a 12 mm diameter sodium hypochlorite solution line with 32 mm ballast piping located adjacent to the intake pipe for zebra mussel control. The intake facility for the Napanee River incorporates a concrete headwall with 600 mm sluice gate and 600 mm diameter and 250 m long gravity intake pipe extending from the sluice gate to the water treatment plant river inlet screens. The Napanee River is only used when water cannot be obtained from Lake Ontario.
Sodium hypochlorite solution is fed to the intake crib when the low lift pumps are operating to control the growth of zebra mussels. The zebra mussel control/pre-chlorination system comprises of a building located on the west side of the existing pump house containing two interconnected sodium hypochlorite solution storage tanks each with a capacity of approximately 5 cubic metres and two chemical feed pumps each rated at 29.2 L/hr feeding sodium hypochlorite solution to either the raw water intake for zebra mussel control or at the low lift pump discharge line for pre-chlorination, equipped with a concrete containment structure and connected to an online chlorine analyzer (Prominent Dulcometer).
The low lift pumping station located at the shore of Lake Ontario, consists of a heated superstructure with a corrugated steel pipe dry well with a suction pipe connected directly to the raw water intake pipe. The low lift pumping station is equipped with two vertical turbine low lift pumps, one pump is rated at 147.3 L/s and the second pump is rated at 94.6 L/s.
A 14.8 km long, 500 mm diameter raw water forcemain conveys water supplied by the low lift pumping station to the raw water reservoirs located on the east side of County Road 8 at the intersection of County Road 8 and Golf Course Lane. The smaller of the two reservoirs, constructed of reinforced concrete, has a capacity of 454 cubic metres. The larger of the two reservoirs is an earth embankment flexible membrane structure having a capacity of 1,800 cubic

metres. Water is conveyed from the two raw water reservoirs to the A.L. Dafoe Water Treatment Plant through approximately 2 km of 400 mm diameter gravity conduit. ______
Site (Name): TREATED WATER Type: Treated Water POE Sub Type: Comments: The A.L. Dafoe Water Purification Plant, servicing the Town of Greater Napanee, is located at 75 East Street, on the west bank of the Napanee River.
At the water treatment plant the 400 mm diameter raw water supply pipe branches into two 200 mm diameter pipes. The two 200 mm diameter raw water supply branch lines converge to feed a common 400 mm diameter pipe upstream of chemical application, temperature monitoring, and flow monitoring points. Raw water flow rate is determined through the use of a Krohne magmeter positioned downstream of the convergence of the branched 200 mm diameter supply conduits.
Liquid aluminum sulphate (alum) is injected into the raw water conduit downstream of the magnetic flow meter; just prior to the water's flow through a Stratiflo in-line static mixer. The coagulant feed system consists of two Prominent diaphragm type chemical metering pumps (one duty and one standby) drawing from a 500 litre day-tank located inside the plant. The alum is stored in two 19,000 L capacity double walled & heated fibre reinforced plastic (FRP) tanks. Downstream of the coagulant injection point, a set of isolation valves dictate the routing of the raw water. The valving permits conveyance of raw water to the coagulation-flocculation tank or to bypass the coagulation-flocculation tank in favour of introducing the water directly into the two sedimentation basins.
Gentle mixing within the 275 cubic metre capacity coagulation-flocculation tank is achieved through the use of baffles. If pressed into service, the Napanee River intake would convey raw water into a small mixing tank where coagulant would be introduced, after which the water would enter the coagulation-flocculation tank. Due to the high colour and turbidity levels associated with the Napanee River this alternate raw water supply scheme would only be used if it became impossible to utilize Lake Ontario water.
As water flows into the coagulation-flocculation tank an equal volume is displaced from the tank and channeled into the two parallel fed sedimentation tanks. Each reinforced concrete sedimentation basin has a capacity of 540 cubic metres and features isolation valves at their influent and effluent extremities.
Clarified effluent from the sedimentation tanks is channeled into two parallel fed rapid sand gravity filters consisting of GAC overlying graded sand. The normal frequency of filter backwashing was reported to be one unit per day. Water level within the filter basins is monitored through the use of ultrasonic sensors backed-up by a contact probes for high flow level alarms. Filter upgrades occurred in 2014, which included replacing existing ceramic underdrains with new lower profile stainless steel underdrains. The media was replaced (gravel, sand and GAC) for sand and GAC. Replaced the existing backwash surface wash system for an air scour and blower system and all associated electrical and programming changes. A Hach 1720E low range turbidity meter is assigned to each of the two filtrate collection pipes. The filtrate collection pipes also feature a valve from which grab-samples can be obtained. When the filters are not being backwashed the filtrate is released into the two clearwells underlying the filters where contact time is achieved. A review of the construction drawings indicates capacities of 490 m3 for clearwell #1 and 500 m3 for clearwell #2. Each clearwell can be bypassed individually. ______
Site (Name): TREATED WATER Type: Sub Type: Comments: Pre-treatment disinfectant can be applied at two locations in the treatment process in accordance with the source water being used. Lake Ontario is the prevalent source of water to the system and pre- treatment is applied at the low lift station. If it was necessary to use the Napanee River as the source water pre-treatment would be applied at a

______
point between the coagulation-flocculation tank. "Post-treatment" disinfectant is applied at the point where filtrate is discharged into the clear well. Disinfectant originates from dual 3.8 m3 capacity sodium hypochlorite storage tanks. A transfer pump is used to convey sodium hypochlorite from the storage tank to a day tank with and approximately capacity of 200 gallons. Diaphragm-type chemical metering pumps (one duty, one standby) draw disinfectant from the day tanks and deliver to the desired application point.
There are three high lift pumps which serve to draw treated water from the clear well and discharge it to the distribution system. In 2003, there was construction of a high lift pumping station located at the pre-existing workshop and garage, housing three horizontal centrifugal pumps (one lead, lag duty & one standby) each rated at 120 L/s, with one of the three pumps being new and the other two relocated from the pre-existing high lift pumping station. One magnetic flow meter is installed in each of the two branches of the discharge header; and one turbidimeter on the plant supply line from the highlift pump discharge header. The installation of an "interlock" to shut down the high lift pumps in the event of a treated water low level free chlorine residual alarm has been completed. Continuous water quality analyzer read-outs are directed to the laboratory/control room. The continuous chlorine analyzer outputs are transmitted to a new SCADA system, along with the turbidity readings sent from the two turbidity units (1720-E Hach) monitoring filter effluent.
Raw water entering the Lake Ontario low lift pumping station is continuously monitored for total chlorine residual. Raw water entering the treatment plant is continuously monitored for free chlorine residual. Treated and distribution waters leaving the plant and entering the distribution system is continuously monitored for free chlorine residual. The filtered water is continuously monitored for turbidity with two turbidity meters, one for each filter effluent. The continuous water quality analyzers are alarmed at the water treatment plant. Both the raw water flow entering the plant and the treated water flow leaving the plant and entering the distribution system are measured by magnetic flow meters.
For emergency power, the A.L. Dafoe Water Treatment Plant includes a portable 150 kW diesel engine generator set. The generator includes a fully automatic transfer switch to immediately supply auxiliary power to all the treatment facility in the event of an interruption to the primary electrical supply. ______
Site (Name): DISTRIBUTION Type: Other Sub Type: Comments: Water is pumped from the high lift pumping station to a 1,140 cubic metre elevated storage tank located on East Street and two booster pumping stations. The McCabe Booster Pumping Station is located at the intersection of McCabe Street and Lennox and Addington County Road 8. This below ground dry well houses two TRW Pleuger booster pumps, each rated to deliver 24.4 litres per second. The Brandon Booster Pumping Station, a reinforced concrete structure, is located at 41 Community Road, house two horizontal centrifugal pumps each rated at 24 L/s at 44m TDH.
An above ground treated water storage tank construction has now been completed and in use for this Drinking Water System. The location of this tank in on County Road #2 just east of Palace Road. This additional 6500 m3 of treated water storage will enable the Town of Napanee to have sufficient treated water storage for fire flow, equalization and emergencies.
The water mains in the distribution system for Napanee range in pipe size and materials (asbestos-cement, ductile iron, cast iron and PVC). The distribution system consists of approximately 87 km of water mains, 425 hydrants and 699 valves. The A.L. Dafoe Water Treatment Plant serves the Town of Napanee with an approximate population of 8,500 persons. ______

______
Comments: The Residue Management Facility (a building with overall dimensions of 10.70 m by 20.38 m) incorporates a 310 cubic metre capacity reinforced concrete backwash equalization tank comprising of an inlet chamber complete with isolation sluice gate for collection of spent filter backwash water, filter-to-waste water, sludge and drainage from sedimentation tanks, and drainage from the coagulation tank. The waste equalization tank is equipped with a float switch to alarm through the SCADA system of a high water level or overflow level with a mixer, two thickener feed pumps (one duty, one standby). Each of the thickener feed pumps are rated between 12 to 20 L/s, to transfer wastewater from the equalization tank to a gravity thickener. The gravity thickener comprises of a Reactor Vessel with polymer addition, Reactor Turbine and variable speed helical gear flocculator. The thickener vessel incorporates a scraper mechanism, sludge circulation system and 0.6 m high lamellar tubes to enhance settling. Discharged supernatant is delivered into the supernatant chamber and thickened sludge is sent to the sludge holding tank. An automatic emulsion polymer preparation and feed system with a capacity to inject 0.6 L/h of polymer into the thickener inlet pipe, consists of a blending system of three zones with mixers for mixing and aging of the emulsion polymer and make up water. In June 2012, the peristaltic chemical feed pump was replaced with a O-Sol Seepex progressive cavity (Delta), and the mixing chamber was replaced with one 305 gallon tank with a mixer (Lightning Model X5-87) for the delivery of the polymer. A reinforced concrete chamber receives the supernatant from the thickener and discharges via 600 mm diameter pipe to the Napanee River. The dechlorination system comprising of two chemical metering pumps, each with a capacity of 0.74 L/hr, feed sodium bisulphite into the supernatant discharge chamber, which is flow paced using the thickener feed pump magnetic flow meter. Chlorine residual in the supernatant is neutralized with the application of sodium bisulphite, drawn from one 20 litre carboy day tank, equipped with an electronic mass scale. The chlorine residual analyzer sample line draws from the supernatant discharge line of the thickener. A reinforced concrete tank with a capacity of 13.5 cubic metres and dimensions of, 2.0 m by 3.46 m by 2.25 m employs two progressive cavity sludge pumps each with a capacity of 4.0 L/s discharging via a 80 mm diameter pipe into the existing sanitary manhole on East Street. The balance of the system incorporates associated instrumentation, controls, electrical, mechanical and the SCADA system. ______

______
Process Wastewater
• The process wastewater discharge monitoring program and discharge quality complied with requirements established in the Municipal Drinking Water Licence Issued under Part V of the SDWA. Process wastewater test parameter annual average concentration limits are cited in condition 1.5 of Schedule C of MDWL #157-101, issue #2, the sample type, frequency and sample locations are cited in condition 4.4 of Schedule C of MDWL #157-101, issue #2.
Records indicate that while the wastewater treatment system was in operation during the inspection period, the effluent discharged to the Napanee river met the monitoring and discharge quality requirements set out in the MDWL. Distribution System
• The owner had up-to-date documents describing the distribution components as required.
• There is a backflow prevention program, policy and/or bylaw in place. By-Law # 1993-01 states that for service connections of 50 mm or less (new and altered services) "The property owner shall install a backflow prevention device at the meter if there is any possibility of backflow from the premises caused either by over pressure in the premises or back siphonage. Back flow preventers shall be registered with the Board".
• The owner had a program or maintained a schedule for routine cleanout, inspection and maintenance of reservoirs and elevated storage tanks within the distribution system.
• Existing parts of the distribution system that are taken out of service for inspection, repair or other activities that may lead to contamination, and all new parts of the distribution system that come in contact with drinking water, were disinfected in accordance with Schedule B, Condition 2.3 of the Drinking Water Works Permit, or an equivalent procedure (i.e. the Watermain Disinfection Procedure). The owner has indicated that drinking water system staff have received training on the Watermain Disinfection Procedure and that staff are referencing the Watermain Disinfection Procedure for watermain breaks and repairs.
• The owner had implemented a program for the flushing of watermains as per industry standards. Records indicate that an annual distribution system flushing program is in place and the activities are conducted during the summer months, typically May through July.
• Records confirmed that disinfectant residuals were routinely checked at the extremities and "dead ends" of the distribution system.
• A program was in place for inspecting and exercising valves. The inspection and operation of valves is a scheduled activity through the workplace management system with the issuance of scheduled work orders.
• There was a program in place for inspecting and operating hydrants. The inspection and operation of hydrants is conducted during the annual flushing program activities.
• There was a by-law or policy in place limiting access to hydrants. By-Law #GNU-1992-02 cites the authority in which who and under what conditions, may operate hydrants within the drinking water system.

______
Distribution System
• The owner was able to maintain proper pressures in the distribution system and pressure was monitored to alert the operator of conditions which may lead to loss of pressure below the value under which the system is designed to operate. Distribution system pressure is monitored and alarmed at the high-lift discharge to the distribution system. Pressure is also monitored at the booster stations, however not alarmed at these locations. Operations Manuals
• Operators and maintenance personnel had ready access to operations and maintenance manuals.
• The operations and maintenance manuals contained plans, drawings and process descriptions sufficient for the safe and efficient operation of the system.
• The operations and maintenance manuals met the requirements of the Drinking Water Works Permit and Municipal Drinking Water Licence issued under Part V of the SDWA. Section 16 of Schedule B in MDWL 157-101 issue #2 prescribes the requirements for Operations and Maintenance Manuals.
A review of the Operations and Maintenance manuals on site found that at the time of the inspection the manuals met the requirements of the MDWL. Logbooks
• Logbooks were properly maintained and contained the required information.
• Records or other record keeping mechanisms confirmed that operational testing not performed by continuous monitoring equipment was being done by a certified operator, water quality analyst, or person who suffices the requirements of O. Reg. 170/03 7-5.
• For every required operational test and every required sample, a record was made of the date, time, location, name of the person conducting the test and result of the test.
• The operator-in-charge ensured that records were maintained of all adjustments made to the processes within his or her responsibility.
• Logs or other record keeping mechanisms were available for at least five (5) years.
Contingency/Emergency Planning
• Spill containment was provided for process chemicals and/or standby power generator fuel.
• Clean-up equipment and materials were in place for the clean up of spills.
• Standby power generators were tested under normal load conditions. Records indicate that standby power generators were tested under load monthly during the inspection period. Security

______
Security
• All storage facilities were completely covered and secure.
• Air vents and overflows associated with reservoirs and elevated storage structures were equipped with screens.
• The owner had provided security measures to protect components of the drinking water system. Water storage facilities within the drinking water distribution sub-system are protected by fences with locked gates. The treatment facility and elevated storage tank control building have locked doors. The treatment facility is also equipped with intrusion alarms. Consumer Relations
• The owner and/or operating authority undertook efforts to promote water conservation and reduce water losses in their system. The owner/operating authority does not impose outdoor watering restrictions however does provide water conservation tips on its website. Leak detection and repair activities help reduce water losses within the drinking water system. Certification and Training
• The overall responsible operator had been designated for each subsystem. Kyle Sinclair is the designated overall responsible operator (ORO) for the A. L. Dafoe water treatment subsystem. Mr. Sinclair holds a valid Class 3 water treatment operators certificate.
Jeff Cuthill is the designated ORO for the A. L. Dafoe water distribution subsystem. Mr. Cuthill holds a valid Class 3 water distribution operators certificate
• Operators in charge had been designated for all subsystems which comprised the drinking-water system. All drinking water system operators that meet the Operator-in-Charge (OIC) training and certification requirements prescribed in O. Reg. 128/04 are designated as OIC for the processes under their charge.
• All activities that were undertaken by uncertified persons in the DW subsystems were overseen by persons having the prescribed qualifications.
• All operators possessed the required certification.
• Only certified operators made adjustments to the treatment equipment.
• An adequately licenced operator was designated to act in place of the overall responsible operator when the overall responsible operator was unable to act.
