2. PROJECT INFORMATION

2.1 Project Background The hamlet of Cherry Grove consists of over 100 residences within the geographical boundary of the hamlet. Between the City of Cold Lake and Cherry Gove there are a number of other subdivisions and individual residences that could potentially benefit from this project. It is one of the priorities of the M.D. Strategic Plan to service this area with a potable water supply. An Area Structure Plan has been developed for Cherry Grove and is attached in ANNEX B. A 250mm potable waterline, connected to the City of Cold Lake water distribution system, is currently servicing the community of Ardmore and is a potential connection point for a supply line to Cherry Grove. This alignment is shown in ANNEX C. The Bonnyville Regional Water Services Commission (BRWSC) operates a 600mm potable water regional transmission line that is also located in close proximity (12 Km) to allow for a connection to supply water to Cherry Grove. This alignment is shown in ANNEX C. The supply of water from either of these locations may allow for many other rural connections along the alignment to Cherry Grove. These additional connections are to be considered when performing the study including the option of supplying water from CLRUSC (Cold Lake Regional Utility Services Commission).

Executive Summary

The Cold Lake Regional Utility Services Commission (CLRUSC) presently provides water to the City of Cold Lake, 4 Wing Cold Lake, Cold Lake First Nations, and the Hamlets of Ardmore and Fort Kent. The CLRUSC is interested in examining opportunities to expand the regional system to service additional municipalities including Cold Lake IR 149B, Hamlet of La Corey, Hamlet of Cherry Grove, Elizabeth Métis Settlement, Town of Bonnyville, Village of Glendon, Hamlet of Therien, Kehiwin IR 123, and areas south of Moose Lake including the Summer Villages of Bonnyville Beach and Pelican Narrows. In order to facilitate discussions, the need for a Regional Water Supply Functional Plan and Feasibility Study has been identified.

Growth Scenarios

The population projections developed have been based on historical population trends, current populations and economic activity. These population projections impact the timing of system improvements and should be reviewed on a regular basis. 5 year and 25 year population targets were developed. The planning targets represent more than a doubling of the regional population by 2032, from the current population of around 25,000 to over 50,000.

Water Servicing

The existing system was analyzed based on the existing water consumption data. It is recommended that the future system be designed for a composite water consumption rate of 375 L/capita/day (average day demand) to correspond with the provincial average. The transmission system was sized for two times the average day demand.

For each alternative, it is recommended that the CLRUSC system be separated from the City of Cold Lake distribution system where possible. It is recommended that the First Nation communities Cold Lake IR 149A and Cold Lake IR 149B be supplied from the Cold Lake North distribution system.

It was assumed that all expansion communities would be serviced by 2012. For all of the alternative water servicing concepts, it is proposed that there be a dedicated fill line from the Water Treatment Plant to a new CLRUSC reservoir/pump station located in Cold Lake North. This pump station will supply all of the regional customers, and a 1500 m3 reservoir will be required.

Four water servicing alternatives were developed. Alternative 1 includes upgrading the existing transmission main from Cold Lake to Fort Kent and extending the main to Bonnyville. From Bonnyville the pipes extend west to service the Moose Lake area, Kehiwin IR 123, Glendon and Therien. For each alternative, the servicing to areas west of Bonnyville is the same. The total length of pipe required is 147 km, and 2 booster stations are required.

Alternative 1a includes the same servicing concept as Alternative 1, with an additional connection from Cold Lake to La Corey for looping. The total length of pipe required is 183 km, and 2 booster stations are required.

RPT2-0089-077-00-FINAL-090227.DOC EXECUTIVE SUMMARY v COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

Alternative 2 includes the installation of a new transmission main from Cold Lake west to La Corey, then south to Bonnyville. The total length of pipe required is 150 km, and 2 booster stations are required.

Alternative 3 includes the installation of a new transmission main south from Cold Lake to Cherry Grove and the Elizabeth Métis Settlement, then west to Bonnyville. The total length of pipe required is 165 km, and 3 booster stations are required.

Present worth costs were determined for each of the alternatives, including both capital costs and operation and maintenance costs for the 25 year study period. The cost estimates include 35% for contingencies and 10% for engineering and overhead, and are summarized in Table ES.1.

Table ES.1: Water Transmission System Cost Estimate Summary

Alternative Present Worth Capital Present Worth O&M Total Present Worth Alternative 1 $102,402,000 $29,716,000 $132,118,000 Alternative 1a $107,416,000 $29,716,000 $137,132,000 Alternative 2 $112,577,000 $29,455,000 $142,032,000 Alternative 3 $134,823,000 $36,547,000 $171,370,000

Alternative 1 is the recommended water servicing concept since it is the most cost effective alternative. In addition, Alternative 1 is the preference of the steering committee. Following submission of the draft report, Alberta Transportation indicated that the maximum annual growth rate should be 2.5%. Therefore, the water demands were adjusted accordingly, and refinements were considered to the Alternative 1 design to determine the most cost effective solution.

The recommended water servicing design includes a 500 mm diameter transmission main from Cold Lake North to Bonnyville, twinning the existing pipes through Ardmore and Fort Kent. Due to the reduced flow rates, only 1,000 m3 of storage is required at Cold Lake South, and the proposed pump station in Cold Lake South was eliminated. The total present worth cost for the recommended alternative (refined Alternative 1) is $119,467,000. The recommended alternative is illustrated in Figure ES.1.

Water Treatment

Demands are expected to exceed the existing plant capacity (22 ML/d) by 2010, and a third membrane train (with a capacity of 13.7 ML/d) should be installed at that time. With its installation, projected 2012 demands (21.8 ML/d) will be easily met.

For long-term servicing, two alternatives were considered. Alternative 1 involves filling out the existing tankage and modifying the remaining tanks to accommodate 2032 demands. Alternative 2 involves the construction of a new treatment plant on the same site as the future CLRUSC pump station and reservoir in Cold Lake North. The existing water treatment plant would be used as a pumphouse and raw water reservoir.

RPT2-0089-077-00-FINAL-090227.DOC EXECUTIVE SUMMARY vi COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

Retrofitting the first and second existing membrane tanks and replacement of the existing membranes with new higher density membranes (with a capacity of 13.7 ML/d) will have to be completed by 2030 and 2034, respectively, in order to meet the projected maximum day demand in 2032 (37.2 ML/d). Modifications to the transfer pumping will have to occur before the addition of the third membrane train, and the addition of a building expansion will be necessary as demands increase. Depending on the supply pressure needed from the water treatment plant, the building expansion and additional transfer pumps may need to occur as early as 2019 (550 kPa) and as late as 2030 (350 kPa).

Cost Estimates and Implementation Plan

The cost estimates for the recommended alternatives, refined water servicing Alternative 1 and water treatment Alternative 1, are summarized in Table ES.2.

Table ES.2: Cost Estimate Summary

Total Capital Present Worth Alternative Cost Present Worth Capital O&M Total Present Worth Water Servicing $116,692,000 $93,904,000 $25,563,000 $119,467,000 (Alternative 1-Refined) Water Treatment $9,676,000 $5,270,000 $13,405,000 $18,675,000 (Alternative 1) TOTAL $126,368,000 $99,174,000 $38,968,000 $138,142,000

Per capita costs were developed for each of the communities, based on the estimated capital costs. The costs were split between communities based on a percentage of total flow through the pump or transmission main, and were based on recommended alternative. Also, the costs were allocated based on the assumption that the excess capacity in the existing system will be utilized by the communities currently serviced by the CLRUSC through 2012. Therefore, the costs for 2012 were allocated to only the expansion communities. Table ES.3 summarizes the estimated cost per person to service each of the communities.

Location Total Capital Cost 2032 Servicing Population Per Capita Cost Town of Bonnyville $39,226,764 11,200 $3,510 Village of Glendon $14,243,218 900 $15,830

As indicated in Table ES.2, the per capita service costs range from $160 to $53,690. As a result, it may not be economically feasible to service some of the communities with high per capita cost.

Stage 1 of the regional system expansion involves the addition of the Town of Bonnyville. To service the Town, the construction of the 500 mm diameter transmission main would be required, as well as the new CLRUSC pump station and reservoir, located in Cold Lake North. The proposed booster station along Highway 28 will not be required at this time. For water servicing, the capital cost for Stage 1 of the recommended alternative is $61,204,000. To service Stage 1 development from the water treatment plant, the upgrades recommended for 2012 would be required. For water treatment, the capital cost for Stage 1 of Alternative 2 is $3,228,000. The total capital cost for Stage 1 is $64,432,000. Stage 1 development is illustrated in Figure ES.2.

Utility Governance Model

The current CLRUSC is comprised of a total of seven board members from the City of Cold Lake, 4 Wing Cold Lake, Cold Lake IR 149 and the MD of Bonnyville.

The CLRUSC determines the conditions under which membership might be extended; there are some issues identified by existing CLRUSC members that would need to be addressed prior to expansion. As a first step in moving forward with the regional water system expansion, the CLRUSC needs to first consider the steps that would be taken and which communities would be serviced during Stage 1 of the expansion.

For Stage 1, it is recommended that the board remain at seven members, with two positions given to the Town of Bonnyville. For the ultimate expansion, it is recommended that the board be expanded to eleven members, with one position given to each additional community. For decision making processes, it is recommended that a one-member, one-vote model be used; however, for financial decisions the board will have the option to undertake a population weighted voting process.

1.0 Introduction

1.1 Background

The Cold Lake Regional Utility Services Commission (CLRUSC) presently provides water to the City of Cold Lake, 4 Wing Cold Lake, Cold Lake First Nations (Cold Lake IR 149 and IR 149A), and the Hamlets of Ardmore and Fort Kent. The water supply is provided by the Cold Lake Water Treatment Plant, which draws water from Cold Lake. The Town of Bonnyville is currently supplied by the Bonnyville Water Treatment Plant, which draws water from Moose Lake. The Town of Bonnyville Water Treatment Plant is aging and requires significant upgrades. However, there are water quality challenges with the water from Moose Lake, and alternative water sources were considered, including a supply from Cold Lake.

The CLRUSC is examining opportunities to expand the regional system to service additional municipalities including Cold Lake IR 149B, Hamlet of La Corey, Hamlet of Cherry Grove, Elizabeth Métis Settlement, Town of Bonnyville, Village of Glendon, Hamlet of Therien, Kehiwin IR 123, and areas south of Moose Lake including the Summer Villages of Bonnyville Beach and Pelican Narrows. In order to facilitate discussions, the need for a Regional Water Supply Functional Plan and Feasibility Study has been identified.

1.2 Scope of Work

The study was carried out under the direction of a steering committee comprised of a representative from each of the member municipalities: City of Cold Lake, 4 Wing Cold Lake, Cold Lake First Nations, M.D. of Bonnyville, Town of Bonnyville, and Village of Glendon. In addition, representatives from Indian and Northern Affairs Canada (INAC), Alberta Infrastructure and Transportation, and Alberta Environment were part of the steering committee, as well as the UMA/AECOM project team. A series of workshops were held with the steering committee to update the committee on the status of the study, to identify issues, to review alternatives and to reach a consensus at key stages.

The first phase of the study involved resolving planning issues by examining factors such as population trends and relevant growth documents to help determine population projections and identify possible growth scenarios.

Once the results of the planning portion of the study were known, examination of water servicing and water treatment alternatives commenced. Water servicing alternatives were examined for the entire service area, including both existing and expansion communities.

The third phase of the project involved a review of the existing governance structure and evaluation of alternative governance structures.

RPT2-0089-077-00-FINAL-090227.DOC INTRODUCTION 1 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

The scope of work is included in Appendix A and includes the following:

Growth Scenarios

The purpose of the growth scenarios was to define planning targets for each municipality and community in the region to be used as the basis for projecting infrastructure needs and to ensure the planning targets are credible and defensible, given the potential magnitude of infrastructure investment. The definition of the growth scenarios was undertaken through the following process:

• Review of historical population trends for each municipality/community within and potentially within the service area, as well as for the region going back at least 25 years. • Identification of past trends both short term and long term and the factors which have affected population and non-residential growth in the past. • Establishment of a 2006 base population based on the most recent population census and recent trends. • Projection of 2006 population forward to the year 2032. • Review of existing plans, analyses and projections for each municipality/community and the overall region – i.e. what existing population targets have been used for purposes of land use (Municipal Development Plan), transportation (Transportation Master Plan) or infrastructure planning by the municipality/community or the regional infrastructure commissions. • Reconciliation of projections and existing targets and relate to the share of regional growth projections to ensure compatibility. • Establishment of approximate 2012 and 2032 planning targets. • Development of growth rates for the non-residential areas. • Review of planning targets with municipal planning representatives in a workshop session and obtain consensus.

Water Servicing

The purpose of the water transmission system assessment was to evaluate the existing water transmission system performance under the existing and future conditions and identify the available capacity to service the study area. The water transmission system assessment was undertaken through the following process:

• Review of the existing service area and expansion area. • Collection and review of all relevant data including as-built plans of existing water transmission mains, pumping facilities, flow monitoring data, and all available water consumption data. • Development of a system model of the existing water transmission system utilizing WaterCAD. The model includes the main transmission system and pump stations only. • Utilization of available monitoring data to calibrate the system model. • Site investigation of major components of the water transmission system within the study area including pump stations. • Review of the performance of the transmission system with operation and maintenance personnel to identify any problem areas including areas of low or high pressure.

RPT2-0089-077-00-FINAL-090227.DOC INTRODUCTION 2 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

• Identification of present and future water demands based on the growth scenarios identified during the planning process. • Assessment of the existing transmission system in terms of capacity to meet existing and projected water demands for the existing and expanded service area. • Development of alternative servicing concepts to address existing and future demands including system upgrades to transmission mains and pump stations. • Evaluation of alternatives based on evaluation criteria and a preferred alternative identified. • A conceptual design of the preferred alternative will be prepared. • Development of cost estimates and an implementation plan for the recommended servicing concept.

Water Treatment

The Cold Lake Water Treatment Plant was evaluated to determine the required upgrading and/or expansion to meet the needs for the regional water supply. A plan for upgrades was developed through the assessment to meet the short term and long term targets of 2012 and 2032. The water treatment plant assessment was undertaken through the following process:

• Collection and evaluation of historical raw water quality data. • Inventory of all infrastructure that is part of the water treatment plant, including: intake, pipelines, pumps, unit processes, disinfection capacity, potable water storage and fire storage. • Collection and review of all past feasibility studies and design reports. • Analysis and interpretation of the source water and water treatment plant. • Development of upgrading and/or expansion alternative(s) for short and long term targets. • A conceptual design of the recommended upgrading and/or expansion plan was prepared. • Development of cost estimates and an implementation plan for the recommended water treatment alternative.

Utility Governance Model

The current governance structure of the CLRUSC will be reviewed, alternative governance structures were evaluated, and an implementation plan will be developed to convert the Commission into a new governance structure, through the following process:

• Collection and review of all information regarding the current CLRUSC governance structure and operation. • Determination of what the needs of the existing and potential members are and the current strengths and shortcomings of the current governance structure. • Review of the costs and benefits associated with the creation of a regional system. • Development and evaluation of alternative governance structures. • Development of a recommended structure including governance roles, decision making, contributions/benefits accruing to each member. • Development of an implementation plan.

On July 7, 2008, an open house was held in the City of Cold Lake, and on July 8, 2008 an open house was held in the Town of Bonnyville.

The open houses provided an opportunity for the public to learn about the project, ask questions of the consultants and representatives from the municipalities, and voice any concerns they may have in an informal, casual setting. The open houses were an informal, drop-in style event. Display panels were arranged on free standing easels for viewing. Light refreshments of coffee, cookies and donuts were provided to attendees. Attendees were encouraged to fill out an evaluation form.

4.0 Growth Scenarios

4.1 Purpose

The purpose of developing growth scenarios was simply to address the question of how many people to plan for within the regional system. Utility needs are fundamentally influenced by the size and location of the population they are intended to serve and by the patterns of water consumption.

Growth scenarios for the communities within the study area were developed with population targets established for 2012 (projected 5 years from 2007) and for 2032 (projected 25 years from 2007).

4.2 Growth Scenarios

4.2.1 Process

The process of developing these growth scenarios involved a number of sequential steps as follows:

• Acquisition and review of historical population trends for each community; • Consideration of growth prospects for each community, based on past trends, location, economic development prospects and demographic factors and selection of three growth rates for projections – a low, medium and high projection; • Establishment of 2007 baseline populations for area communities; • Forward projections for low medium and high growth rates to the year 2032 to determine a range of population targets; • Discussion with the steering committee to select the most appropriate population targets based on both historical trends and prospects for future development.

The growth scenarios and population targets thus represent a convergence of technical analysis and informed judgement by the consultants and steering committee.

The term ‘population target’ is less deterministic than ‘population projection’. The population target represents a threshold population, which requires regular monitoring to estimate the timing for the attainment of the target. An increase in growth and development could advance the achievement of the target. Conversely, a decrease in growth could prolong achieving the target, hence the need for regular monitoring.

4.2.2 Data Challenges

A number of challenges were experienced in the collection, analysis and comparability of data.

First, several databases were used, including Statistics Canada, Alberta Municipal Affairs and Housing and Indian and Northern Affairs Canada (INAC). In addition, two larger communities have recently conducted their own municipal censuses. Inconsistencies and varying time periods between databases were reconciled to the extent possible, based on the consultants’ experience of the accuracy and applicability of data.

RPT2-0089-077-00-FINAL-090227.DOC GROWTH SCENARIOS 11 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

The City of Cold Lake was formed in 2001 to combine the former Town of Grand Centre, the former Town of Cold Lake and 4 Wing Cold Lake (Department of National Defence). Statistical reporting has not been consistent over time as Statistics Canada data for 4 Wing Cold Lake was limited prior to the merger.

Population statistics for the Cold Lake First Nation reserves are available annually from the Indian and Northern Affairs Canada database for the entire population of the Nation. The database also provides a break down between on- and off-reserve populations. However, there is no break down of on-reserve population between the three reserves. However, this break down is available from Statistics Canada as Reserve 149 with 75%, Reserve 149A with 7% and 149B with 18% of total population. Thus the final population estimates combined data from two sources to best reflect the population for the three communities.

Population statistics were limited for smaller centres in the study area such as the Hamlets of Ardmore, Fort Kent, La Corey, Therien, Cherry Grove and the Elizabeth Métis Settlement. Except for the Elizabeth Settlement, these hamlets are within the Municipal District of Bonnyville. Population reporting is inconsistent. Estimates of population and population change were informed by discussions with the M.D. of Bonnyville and an analysis of the overall population trends within the Municipal District.

The population of the area around Moose Lake posed a particular challenge. Some assumptions were made about the percentage of seasonal and permanent population, the build-out of unoccupied lots and the potential build-out of currently non-developed land. These assumptions were based on a count of subdivided lots and a count of lots occupied by a residence. Data for the permanent population of incorporated villages was available from Statistics Canada, and was compared with the number of residences for these villages. A variety of sources were used to make the projections and it is felt that these represent the best estimates available under the circumstances.

The region, typical of resource based communities elsewhere, has a ‘shadow population’ representing temporary workers housed in work camps, motels and other accommodation. The size and significance of this portion of the population is generally very difficult to estimate, especially when it is dispersed throughout the region.

Finally, the initial projections were made in early 2007, prior to the release of 2006 census data. The 2006 data, released in May of 2006, was used to check the validity of the 2006 estimates and any required adjustments were made accordingly.

4.3 Analysis

4.3.1 Long Term Historical Population

Historical population data from 1966 to 2001 were collected for the Cities, Towns, Hamlets, First Nations and Métis Settlement within the study area. This data provides perspective on long term population trends as a first step toward identifying future population targets (Table 4.1).

RPT2-0089-077-00-FINAL-090227.DOC GROWTH SCENARIOS 13 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

The data was analyzed to show (1) the overall percentage population change in the 25 year period between 1976 and 2001 and (2) the annual percentage rate of change in the 25 year period. Although the population data goes back to 1966, the 25 year interval was chosen to correspond to the same time period for future targets. In addition, the formation of the City of Cold Lake by combining three former towns lessens the degree of comparability between 1966 and later inter-census data.

The population data shows that all communities showed positive growth during the 25 year period.

The Town of Bonnyville showed over a 25 year period from 1976 to 2001 a positive increase in population of 3.20% (2589 to 5709 people). The City of Cold Lake (Town of Cold Lake and Town of Grand Centre) (1976 to 1996) shows a significant increase with an annual growth rate of 4.40% (3420 to 8265 people) over a 20 year period. Cold Lake First Nation on-reserve population over a 30 year period (1976 to 2006) has had a population increase at 2.1% annually from 623 to 1219. The future population could be influenced by a return of off-reserve population to the home communities, and by development of the reserve adjacent to the City of Cold Lake.

The Village of Glendon with its small population in 2001 of 459 people has increased by 1% annually over 25 years (from 1976 to 2001). Future population will reflect the level of resource development in the area. Similarly, the smaller hamlets, although growth may have been modest, may grow substantially in response to resource development within the area and to the amenity of a consistent water supply.

4.3.2 Short-Term Historical Population

The next step in the analysis was to look at short-term population changes between 1991 and 2001, and also since 2001 where municipal census data were available.

It is evident that the rate of population growth has been increasing steadily during the 1990s and early part of this century. Incorporated in 1996 through amalgamation of the former towns of Grand Centre, Cold Lake and Canadian Forces Base 4 Wing, Cold Lake became a city in 2000. The three main industries in the area are military, oil and gas industry and tourism. Since 2001, strong economic growth and a corresponding increase in development have occurred in most centres in the study area.

The pace of population growth slowed in the early 1990s and early in the 2000s. The Town of Bonnyville had a growth rate of 2.30% between 1996 and 2001 and decreased to 0.8% between 2001 and 2005. This trend is also reflected in the City of Cold Lake where the annual growth rate decreased from 1.30% between 1991 and 1996 to 0.70% between 2001 and 2002 (Municipal Census). However, these are not necessarily the basis for long-term projections, as they reflect conditions within the province. The vigorous growth rates experienced in the province last three to four years have been well documented in various reports and the media.

The Cold Lake First Nation annual growth percentage decreased from 2.60 over a 15 years period from 1991 to 2006 to 1.20% for a 5 year period between 2001 and 2006, while the Village of Glendon’s annual growth percentage increased to 1.90% over the 5 years from 1996 to 2001.

The analysis of population for smaller centres was hampered by the lack of population data as indicated in Section 4.2.2. However, best estimates of 2006 populations were made based on available data and informed judgment relating to the growth prospects for these places.

4.4 Population Planning Targets

The long and short term population data were used to inform the determination of long term population targets as described in the previous sections. Table 4.2 shows 5 year and 25 year population targets for the currently serviced and proposed expansion communities. The target populations provide the best estimate for the short term and long term growth in the centres within the study area.

Table 4.2: Target Populations

2006 2007 2012 2032 Census 5 Year 25 Year Community/Municipality (Stats Can) Estimate Target Target City of Cold Lake 11,991 12,720 15,000 27,000 Town of Bonnyville 5,832 6,014 8,000 15,000 Cold Lake First Nation Cold Lake IR 149 438 914 1,050 1,500 Cold Lake IR 149A 49 85 100 140 Cold Lake IR 149B 105 220 250 360 Kehiwin First Nation 1,007 1,037 1,200 2,000 Elizabeth Métis Settlement 600 700 1,000 Village of Glendon 421 500 700 1,200 M.D. of Bonnyville 10,194 Hamlet of Ardmore 277 300 500 Hamlet of Fort Kent 166 175 300 Hamlet of La Corey 75 100 200 Hamlet of Cherry Grove 200 300 500 Hamlet of Therien 75 100 200 Moose Lake Area 1,500 1,700 2,500 Included in Included in Included in S.V. of Pelican Narrows 141 (permanent) Moose Lake Moose Lake Moose Lake Included in Included in Included in S.V. of Bonnyville Beach 97 (permanent) Moose Lake Moose Lake Moose Lake TOTAL - 24,383 29,675 52,400

The planning targets represent more than a doubling of the regional population, from the current population around 25,000 to somewhat over 50,000 population.

Following the June 6, 2008 meeting with Alberta Transportation and Alberta Environment, the maximum overall annual growth projection for any community was adjusted to 2.5%. As a result, the population targets Town of Bonnyville and the Village of Glendon were reduced. For the Town of Bonnyville, the population targets for 2012 and 2032 were reduced to 6,800 and 11,200 from 8,000 and 15,000 respectively. For the Village of Glendon, the population targets for 2012 and 2032 were reduced to 550 and 900 from 700 and 1,200 respectively.

5.0 Water Servicing

5.1 General

This section discusses the design criteria, development of the model, and modelling and assessment of the existing water transmission system for the existing service area and expansion communities. Alternative servicing concepts were identified for the future development of the currently serviced areas and the expansion communities.

Proposed pump and pipe upgrades were identified to ensure that the design criteria were met for the current and future demand requirements. Costs were generated for the alternative servicing concepts for the short and long term development scenarios.

5.2 Design Criteria

5.2.1 Pressure and Flow Requirements

The design criteria used in this study are as follows:

• Minimum pressure in the transmission main 140 kPa (20 psi) • Maximum pressure in the transmission main (AC/PVC/PE) 700 kPa (100 psi) • Maximum pressure in the transmission main (Steel) 1100 kPa (160 psi) • Minimum pressure at the fill valve at the reservoir 70 kPa (10 psi) • Maximum flow velocity 2.5 m/s (8.2 ft/s) • Hazen-Williams “C” value (AC) 100 • Hazen-Williams “C” value (PVC/PE/Steel) 120

5.3 Water Supply

The Cold Lake Regional Utility Services Commission (CLRUSC) supplies water from the Cold Lake Water Treatment Plant to the regional customers. The Water Treatment Plant draws from Cold Lake and is capable of supplying 22 ML/day. It was assumed that the Water Treatment Plant is productive for 20 hours per day. Therefore, the supply line from the Water Treatment Plant was sized to convey the 24 hour demand in a 20 hour period; corresponding to a peaking factor of 1.2. Details of the Cold Lake Water Treatment Plant are provided in Section 6.

5.3.1 Water Consumption Rates

Existing water consumption data was available for the City of Cold Lake, 4 Wing Cold Lake, Cold Lake IR 149, Ardmore and Fort Kent. Data was also available for the Town of Bonnyville and the Village of Glendon. For communities with truck fill stations, the bulk water demands were separated from the consumption data to obtain a more accurate representation of the existing per capita demands. The existing system was analyzed based on the existing water consumption rates.

RPT2-0089-077-00-FINAL-090227.DOC WATER SERVICING 16 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

In determining the design water consumption rates, existing water demands as well as the servicing standards were taken into consideration. The water consumption rates for each respective City, Town and County, as specified in the available servicing standards summarized in Table 5.1. Water consumption rates for the commercial, institutional and industrial areas are not specified in any of the servicing standards.

Table 5.1: Water Consumption Rates (ADD) – Municipal Standards

Per Capita Consumption Community / Municipality (L/d/person) City of Cold Lake 350 Town of Bonnyville 500 M.D. of Bonnyville 500 INAC 180

As indicated in Table 5.1, the servicing standards range from 180 L/capita/day to 500 L/capita/day for average day demand.

The provincial average for average daily water consumption is between 375 L/capita/day and 400 L/capita/day. For the future scenarios, a composite rate of 375 L/capita/day was applied to all communities. Although several communities are currently consuming at a rate greater than 375 L/capita/day, through water conservation measures and public education the water consumption rates can be reduced in the future.

For each of the communities, the average day demand (ADD) and maximum day demand (MDD) were identified. Since daily consumption data was not available, the maximum day demand was calculated as two times the average day demand. Available water consumption data from previous years was analyzed to determine the actual per capita water consumption rates for each community. The actual per capita water consumption data was compared to the servicing standards, to determine if the standards are appropriate.

Although the City of Cold Lake includes 4 Wing Cold Lake, the water consumption rates were analyzed separately due to the differences in land use and projected growth.

Actual 2006 water consumption rates and projected water demands for each municipality for the years 2012 and 2032 are summarized in Table 5.2.

Growth projections were based on the information provided in Section 4 of this report. 2. Actual consumption data was provided by the respective municipalities. 3. The growth rate for truck fill stations was assumed to be the same as population growth.

For the City of Cold Lake, the composite average day demand was calculated to be approximately 471 L/capita/day, including both residential and non-residential demands. The Cold Lake Engineering Standards state that the per capita design consumption should be 350 L/capita/day for average day demand. The actual average day demand may be higher than the standards due to the non-residential demands. It should be noted that Cold Lake North has a much higher per capita consumption rate than Cold Lake South (530 L/c/d compared to 400 L/c/d). This is likely due to the differences in the current water billing systems between Cold Lake North and Cold Lake South.

For 4 Wing Cold Lake, based on the current population and the water consumption data, the average day demand for 4 Wing is approximately 661 L/capita/day. The high water consumption rate for 4 Wing Cold Lake is partially due to an influx of people for 6 to 8 weeks during the Maple Flag Operations.

For the Village of Glendon, the composite average day demand was calculated to be approximately 585 L/capita/day, including both residential and non-residential demands. The engineering standards for the M.D. of Bonnyville state that a per capita consumption rate of 500 L/capita/day be used for average day demand.

For the projected 2012 development scenario, the total population is estimated to be 29,675, with an average day demand of approximately 132 L/s. For the projected 2032 development scenario, the total population is estimated to be 52,400, with an average day demand of approximately 233 L/s. The water servicing system will be designed to supply maximum day demand, which was assumed to be 2.0 times the average day demand.

Water Act licences for Cold Lake and Bonnyville were reviewed and compared to existing and projected demands. In Alberta, there is a “first in time, first in right” policy for granting and administering water allocations; however, water allocations will be transferable to ensure societal demands and needs can be met.

5.3.2 Storage

The storage reservoirs at the supply points were not included in this study as the storage requirements depend on various criteria and may be different for each community. The storage reservoirs will be the responsibilities of each municipality. Some of the key criteria are as follows:

• Operational storage requirements are generally based on the day to day and seasonal needs (makeup storage may depend on 5 or 7 days) • Fire storage • Level of service • Peaking factors (varies from 3 to 4 times ADD for peak hour demand).

It is recommended that the City of Cold Lake storage reservoirs be sized based on the Alberta Environment storage requirement. As per the 2006 Alberta Environment Standards and Guidelines for Municipal Waterworks, Wastewater & Storm Drainage Systems, the storage requirements include fire storage, equalization storage (25% MDD) and emergency storage (15% ADD) if the treatment plant is capable of supplying at the maximum day demand.

However, it is recommended that all other regional customers design their storage reservoirs with two average days’ storage plus fire storage. Design of two average days’ storage helps to collectively manage the high 5 day draw rates in the system. This storage recommendation also provides redundancy in the system in case of a disruption to the supply main.

5.4 Existing System Description

All areas currently serviced by the Cold Lake Regional Utility Services Commission are supplied by the Cold Lake Water Treatment Plant. The Cold Lake Water Treatment Plant draws raw water from Cold Lake. There is a dedicated fill line from the Cold Lake Water Treatment Plant to a meter vault located at 4 Wing Cold Lake, where the transmission mains to Cold Lake IR 149, Cold Lake South and 4 Wing Cold Lake branch off. The Cold Lake South transmission main fills the west reservoir in Cold Lake South (Building 7), which fills the east reservoir at night (Building 10). The west pump station operates at night and the east pump station operates during the day to pressurize the distribution system. The transmission main to Ardmore and Fort Kent is fed from the Cold Lake South water distribution system. There is also a dedicated supply line from the Cold Lake Water Treatment Plant to the Cold Lake North reservoir (Building 5). Cold Lake IR 149A is currently serviced as part of the Cold Lake North distribution system.

The existing water transmission system is illustrated in Figure 5.1.

There are three reservoirs in Cold Lake; one in Cold Lake North and two in Cold Lake South. There are also reservoirs in Fort Kent, Ardmore, 4 Wing Cold Lake, and Cold Lake IR 149, at the supply points.

There are no booster stations or pressure reducing valves (PRVs) along the transmission system. There is a water meter along the transmission main feeding 4 Wing Cold Lake, to meter the supply to 4 Wing Cold Lake, Cold Lake IR 149, and Cold Lake South, including Ardmore and Fort Kent. There are also water meters at the supply points to the Fort Kent and Ardmore reservoirs.

RPT2-0089-077-00-FINAL-090227.DOC WATER SERVICING 20 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

The dedicated transmission main from the Cold Lake Water Treatment Plant to Cold Lake North is 500 mm in diameter. The transmission main from the Cold Lake Water Treatment Plant to 4 Wing Cold Lake is a twinned line (400 mm and 300 mm diameters). The transmission main from 4 Wing Cold Lake to Cold Lake South is a twinned line with 150 mm and 250 mm diameters. The transmission main to Ardmore is 250 mm in diameter. There is an abandoned water treatment plant between Ardmore and Fort Kent. From Ardmore to the old water treatment plant, the transmission main is 150 mm in diameter, which reduces to a 100 mm diameter transmission main that continues to Fort Kent. The supply line to Cold Lake IR 149 from the meter vault is 150 mm in diameter.

The transmission mains to the meter vault and the main to 4 Wing Cold Lake are all polyvinyl chloride (PVC). The transmission main from the meter vault to Cold Lake South is polyethylene (PE). The Ardmore/Fort Kent transmission main is mainly PVC pipe. For structural purposes and trenchless installation, the material of the transmission main is high density polyethylene (HDPE) at the creek and river crossings. The transmission main to Cold Lake IR 149 is mainly asbestos cement with sections of carbon steel pipe.

In addition to the local distribution systems in Ardmore and Fort Kent, both communities have truck fill stations. Cold Lake North also has a truck fill station, located at the reservoir site (Building 5).

The existing pump design capacities of the pumps that are currently part of the regional system are summarized in Table 5.3, and the available pump curves are included in Appendix C.

The Cold Lake Water Treatment Plant supplies water at a pressure of 350 kPa to the 4 Wing supply line and the Cold Lake North reservoir. The 300 mm and 400 mm diameter 4 Wing supply lines are fed from the 300 mm and 350 mm diameter headers in the water treatment plant, respectively. The west reservoir in Cold Lake South operates at a pressure of 625 kPa to pressurize the Cold Lake South distribution system and the Ardmore/Fort Kent transmission main at night. Due to the high elevation, the east reservoir in Cold Lake South operates at a pressure of 425 kPa to pressurize the Cold Lake South distribution system and the Ardmore/Fort Kent transmission main during the day.

5.5 Existing System Assessment

5.5.1 Model Development

The existing water transmission system for the service area was modelled using the WaterCAD version 6.5 program developed by Haestad Methods Inc. This program is a steady state as well as extended period simulation program. The software used pull-down menus for data entering and editing along with the AutoCAD based graphical interface. The software allows review of the simulation results graphically on the screen; the graphical results can also be plotted.

The program requires physical details of the existing transmission system to represent the system through pipes and junction nodes such as pipe diameters, lengths, roughness coefficients, water consumption demands, and ground elevations.

As the model spans a 25 year period, it is reasonable to conclude that the pipe roughness coefficient will increase. Information was not available to calibrate the regional model. Subsequently, roughness coefficients of 120 for PVC and steel pipes and 100 for asbestos cement pipes were used for the study, as indicated in Section 5.2.1.

5.5.2 System Modelling and Assessment

The existing transmission system was analyzed for maximum day demand. The simulated pressures at the existing supply points, as well as at key points in the system, are summarized in Table 5.4.

Table 5.4: Existing System Maximum Day Demand Modelled Results

Location Elevation (m) Modelled Pressure (kPa) Cold Lake Building 5 Reservoir 530 420 Cold Lake Meter Vault 530 369 4 Wing Cold Lake Reservoir 542 249 Cold Lake Building 7 Reservoir 530 317 Beaver River Crossing 495 962 Ardmore Reservoir 556 345 Fort Kent Reservoir 550 310 Cold Lake IR 149 Reservoir 538 248

As indicated in Table 5.4, the modelled pressure at the Beaver River crossing during maximum day demand is 962 kPa. The section of pipe crossing under the river is HDPE DR 9, which has a maximum pressure rating of approximately 1380 kPa (200 psi).

5.6 Water Servicing Concept

5.6.1 Development of Alternatives

For each alternative, it is recommended that the Commission system be separated from the City of Cold Lake distribution system where possible.

RPT2-0089-077-00-FINAL-090227.DOC WATER SERVICING 22 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

It is recommended that there be a dedicated fill line from the Water Treatment Plant to a new CLRUSC reservoir and pump station located west of the Cold Lake North reservoir (Building 5). It is recommended that the existing 500 mm fill line to Cold Lake North continue to be used as a dedicated fill line to Cold Lake North, and the 300 mm and 400 mm diameter transmission mains to the meter vault be disconnected and tied in to the new reservoir. The new CLRUSC pump station / reservoir will be the supply source for all of the regional customers, excluding Cold Lake North.

As described further in Section 6, modifications will be required to the transfer pumps at the Cold Lake Water Treatment Plant to allow for expansion.

It is recommended that Cold Lake IR 149A continue to be supplied from the Cold Lake North water distribution system. It is also recommended that Cold Lake IR 149B be supplied from the Cold Lake North water distribution system due to the close proximity of the existing water distribution system to Cold Lake IR 149B. Since these communities are proposed to be serviced by the local distribution system, not the regional line, the pressures at the distribution points were not modelled as part of this study. However, the pressures should be supplied through the distribution system at a minimum of 140 kPa.

The general philosophy for pipe upgrades used in this study was to size the pipes for the year 2032. It was assumed that all communities will be serviced by 2012. Initially, three water servicing alternatives were developed. Following Workshop 3, Alternative 1 was revised to include a small diameter main from Cold Lake to La Corey, creating Alternative 1a. All alternatives consider servicing all of the communities included in the study

5.6.2 Alternative 1

Alternative 1 involves twinning the existing Ardmore/Fort Kent transmission main, and extending the transmission main to Bonnyville. From Bonnyville, the transmission main will split north to service La Corey, and west to service the Moose Lake area. From Moose Lake, the west transmission main will split again, and continue south to service Kehiwin IR 123 and west to service Glendon and Therien. A separate transmission main will be installed from Cold Lake to Cherry Grove and the Elizabeth Métis Settlement. A CLRUSC pump station will be required in Cold Lake South, adjacent to the existing west reservoir and pump station (Building 7). Two booster stations will be required; one at Fort Kent, and one south of Moose Lake. The existing 150 mm diameter main to Cold Lake IR 149 is adequate to supply the 2032 demands and will therefore not require upgrades. However, it is recommended that the existing main be tied into the CLRUSC pump station in Cold Lake South. Figure 5.2 illustrates the servicing concept for the entire region. Figure 5.3 illustrates the servicing concept for the Cold Lake area.

The Alternative 1 water servicing concept was simulated for the maximum day demand condition. The simulated pressures at the supply points to each community are summarized in Table 5.5.

Detailed staging of the required components of the water servicing system is outlined in Table 5.6. Since it was assumed that all communities will be serviced by 2012, all of the pipe lengths are required by 2012. As summarized in Table 5.6, Alternative 1 requires approximately 147 km of pipe, ranging in diameter from 150 mm to 600 mm.

As indicated in Table 5.7, the total present worth cost of the pumps and pipes required for Alternative 1 is $132,118,000. This cost does not include the water treatment plant upgrades, which are included in Section 6.

5.6.3 Alternative 1a

Alternative 1a involves twinning the existing Ardmore/Fort Kent transmission main, and extending the transmission main to Bonnyville. From Bonnyville, the transmission main will split north to service La Corey, and west to service the Moose Lake area. The west transmission main will split again, and continue south to service Kehiwin IR 123 and west to service Glendon and Therien. A small diameter main from Cold Lake to La Corey will also be installed to provide a loop in the system. A separate transmission main will be installed from Cold Lake to Cherry Grove and the Elizabeth Métis Settlement. A CLRUSC pump station will be required in Cold Lake South, adjacent to the existing west reservoir and pump station (Building 7). Two booster stations will be required; one at Fort Kent, and south of Moose Lake.

The existing 150 mm main to Cold Lake IR 149 is adequate to supply the 2032 demands; however, it is recommended that the existing main be tied into the proposed CLRUSC pump station in Cold Lake South. Figure 5.4 illustrates the servicing concept for the entire region and Figure 5.5 illustrates the servicing concept for the Cold Lake area.

Detailed staging of the required components of the water servicing system is outlined in Table 5.9. Since the additional loop from Cold Lake to La Corey is not required hydraulically, but for redundancy in the system, it was assumed to be part of only the ultimate system. As summarized in Table 5.9, Alternative 1a requires approximately 183 km of pipe, ranging in diameter from 150 mm to 600 mm.

As indicated in Table 5.10, the total present worth costs of the pumps and pipes required for Alternative 1a is $137,132,000, and does not include the upgrade costs for the Cold Lake water treatment plant.

5.6.4 Alternative 2

Alternative 2 involves the installation of a new transmission main west from Cold Lake to La Corey. From La Corey, the transmission main will continue south to supply Bonnyville. From Bonnyville, the servicing for the Moose Lake area, Kehiwin IR 123, Glendon and Therien will be the same as in Alternative 1. A separate transmission main will be installed from Cold Lake to Cherry Grove and the Elizabeth Métis Settlement. Additional pumping will be required in Cold Lake South. Since the pumping requirements at this location are low for Alternative 2, the required pumps may be able to be added into the existing pump station at Building 7. Two booster stations will be required; one along Highway 55 near Edward Lake, and one south of the Summer Village of Bonnyville Beach. The existing transmission main to Ardmore and Fort Kent is adequate to supply the 2032 demands; however, to provide a loop in the system a small diameter main is proposed between Bonnyville and Fort Kent. The existing 150 mm main to Cold Lake IR 149 is adequate to supply the 2032 demands; however, it is recommended that the existing main be tied into the new pumps in Cold Lake South. Figure 5.6 illustrates the servicing concept for the entire region. Figure 5.7 illustrates the servicing concept for the Cold Lake area.

The Alternative 2 water servicing concept was simulated for the maximum day demand condition. The simulated pressures at the supply points to each community are summarized in Table 5.11.

Detailed staging of the required components of the water servicing system is outlined in Table 5.12. Since the additional loop from Bonnyville to Fort Kent is not required hydraulically, but for redundancy in the system, it was assumed to be part of only the ultimate system. As summarized in Table 5.12, Alternative 2 requires approximately 150 km of pipe, ranging in diameter from 150 mm to 600 mm.

5.6.5 Alternative 3

Alternative 3 involves the installation of a new transmission main to Cherry Grove, which will continue south to the Elizabeth Métis Settlement, and west to Bonnyville. From Bonnyville, the water main will split north to service La Corey, and west to service the Moose Lake area. The servicing for the Moose Lake area, Kehiwin IR 123, Glendon and Therien will be the same as in Alternative 1. A CLRUSC pump station will be required in Cold Lake South, adjacent to the existing west reservoir and pump station (Building 7). Three booster stations will be required; one north of the Elizabeth Métis Settlement, one west of Bonnyville, and one south of Moose Lake. The existing transmission mains to Fort Kent and to Cold Lake IR 149 are adequate to supply the 2032 demands. However, it is recommended that a small diameter main be installed between Bonnyville and Fort Kent to provide a loop in the system. Figure 5.8 illustrates the servicing concept for the entire region. Figure 5.9 illustrates the servicing concept for the Cold Lake area.

As indicated in Table 5.16, the total present worth of the pumps and pipes required for Alternative 3 is $171,370,000, and does not include the upgrade costs for the Cold Lake water treatment plant.

Figures 5.10 to 5.13 summarize the ultimate flow rates and velocities, for the year 2032, in individual pipes for each of the alternative servicing concepts.

5.6.6 Cost Estimate Summary

The cost estimates are presented in present worth dollars and include both transmission mains and pumps. The pump costs are based on a per horsepower capital cost of $2300, with a minimum cost of $24,000. Where a new pump station will be required, a pump cost of $4600 per horsepower was used to account for the cost of the building. A unit cost of $0.12/kW was used to determine the operational cost of the pump, with the maintenance cost based on a 15-year pump and 25-year enclosure life expectancy. The present worth was calculated based on an inflation rate of 2% and an interest rate of 6%. Pipe life expectancy of 75 years was used and the operation costs were assumed to be included in the rates.

Table 5.17 summarizes the present worth cost estimates for each of the alternatives, including capital costs and operation and maintenance (O&M) costs. The costs do not include the water treatment costs. Preliminary cost estimates are detailed in Tables D.1 to D.4 in Appendix D.

Table 5.17: Water Transmission System Cost Estimate Summary

As indicated in Table 5.17, there is less than 10% difference between the total present worth of Alternatives 1, 1a and 2. However, the present worth costs for Alternative 3 are approximately 30% higher than Alternative 1.

5.7 Evaluation of Alternatives

Alternatives were evaluated based on the following criteria:

• Technical feasibility • Environmental impact • Ease of operation and maintenance • Ease of implementation • Stakeholder acceptability • Utilization of existing infrastructure • Staging flexibility • Land/easement availability • Annual operation and maintenance costs • Life cycle costs • Total capital cost

All of the proposed servicing concepts meet the design requirements; however, the alternatives provide various levels of service to the municipalities. The advantages and disadvantages of the alternatives are summarized in Table 5.18.

5.8 Recommended Water Servicing Alternative

All alternatives meet the necessary requirements for future development conditions within the study area. Alternative 1 is the recommended water servicing concept since it is the most cost effective solution. In addition, Alternative 1 is the preference of the steering committee.

5.9 Conceptual Design of Preferred Alternative

5.9.1 Growth Projections

The population targets detailed in Section 4 were determined through analysis of historical data and discussions with the steering committee. Subsequently, Alberta Transportation indicated that an annual growth rate of 2.5% should not be exceeded in the design of regional systems.

For ultimate development, the communities affected by the limiting growth rate are the Town of Bonnyville and the Village of Glendon. For the Town of Bonnyville, the original population targets were 8,000 and 15,000 people for the years 2012 and 2032, respectively. A 2.5% annual growth rate corresponds to population targets of 6,800 and 11,200 people for the years 2012 and 2032. Based on discussions with the Town of Bonnyville, the Town is supportive of reducing the growth projections. For the Village of Glendon, the original population targets were 700 and 1,200 people for the years 2012 and 2032, respectively. A 2.5% annual growth rate corresponds to population targets of 550 and 900 people for the years 2012 and 2032. The maximum day demand rates were adjusted accordingly. Table 5.19 indicates the actual and projected water consumption rates for municipalities.

The average day demand for the Town of Bonnyville for 2012 and 2032 is approximately 30 L/s and 50 L/s, reduced from 36 L/s and 67 L/s in the April 2008 draft report, respectively. The average day demand for the Village of Glendon for 2012 and 2032 is approximately 2.4 L/s and 3.9 L/s, reduced from 3.0 L/s and 5.2 L/s.

5.9.2 Recommended Design

As mentioned in Section 5.8, Alternative 1 is the recommended design. Refinements were considered to the Alternative 1 design to determine the most cost effective solution. Initially a 400 mm diameter transmission main was proposed to replace the existing 300 mm diameter transmission main from Cold Lake North to Cold Lake South and twin the existing 400 mm diameter transmission main. The twin 400 mm diameter transmission mains were proposed to feed into the new CLRUSC pump station in Cold Lake South, which is required for the ultimate system to boost the pressure along the transmission mains to Bonnyville, Cold Lake IR 149, and Cherry Grove. For Stage 1 development, a 500 mm diameter transmission main was considered to twin the existing 400 mm diameter transmission main, which eliminates the need for the new CLRUSC pump station in Cold Lake South. The 500 mm diameter transmission main with the elimination of the pump station is a more cost effective solution than the initially proposed Alternative 1. However, it should be noted that ultimately a booster station will be required along the existing transmission main to Cold Lake IR 149, and an additional booster station will be required south of Moose Lake. In addition, if Cherry Grove and the Elizabeth Métis Settlement become part of the regional system, a booster station will be required along that transmission main.

The recommended alternative was simulated for the maximum day demand condition, based on the projected flow rates in Table 5.19. The simulated pressures at the supply points to each community are summarized in Table 5.20.

Since it was assumed that all communities will be serviced by 2012, all of the pipe lengths are required by 2012. As summarized in Table 5.21, the recommended Alternative requires approximately 144 km of pipe, ranging in diameter from 150 mm to 500 mm.

As indicated in Table 5.22, the total present worth of the pumps and pipes required for the recommended alternative is $119,467,000, which does not include the upgrade costs for the Cold Lake water treatment plant.

Servicing the Town of Bonnyville with a 500 mm diameter transmission main has the lowest capital costs since the additional pumping costs are greater than the incremental pipe cost when evaluating servicing only the Town of Bonnyville as well as servicing all communities. A 500 mm diameter transmission main will support the entire regional system.

The diameters of the proposed transmission mains for the recommended alternative are shown in Figures 5.14 and 5.15. The alignment of the proposed 500 mm diameter transmission main will be from the new CLRUSC pump station south through Cold Lake South, then southwest to Ardmore, Fort Kent and Bonnyville. The water main from Cold Lake to Bonnyville should be located along the rail line where possible. From Bonnyville, the transmission main will split north to service La Corey and west to service the remaining communities. The west transmission main will follow the shore of Moose Lake to Highway 28. At Highway 28, the transmission main will split to service Kehiwin IR 123 and Glendon. The transmission main south to Kehiwin will be located along Highway 28. The water main west to Glendon should be located such that the number of water crossings is minimized. From Cold Lake South, the proposed water main to Cherry Grove and the Elizabeth Métis Settlement should follow Highway 53 to Cherry Grove, then south to the Elizabeth Métis Settlement. As the existing pipes should be in good condition, it is recommended that the pipes be utilized where possible.

As mentioned in Section 5.6.1, it is recommended that the 300 mm and 400 mm diameter transmission mains to the meter vault be disconnected and tied into the new reservoir in Cold Lake North with a 500 mm diameter pipe. The new CLRUSC pump station will be the supply source for all of the regional customers, excluding Cold Lake North and the Cold Lake First Nations (Cold Lake IR 149A and 149B).

RPT2-0089-077-00-FINAL-090227.DOC WATER SERVICING 38 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

Cold Lake North and the Cold Lake First Nations (Cold Lake IR 149A and 149B) will continue to be serviced from an existing 500 mm diameter supply line to the Cold Lake North reservoir.

There are several river and creek crossing necessary for Alternative 1. The 500 mm diameter main will cross under the Beaver River along Highway 28, between Cold Lake and Ardmore. The 150 mm diameter main between Bonnyville and La Corey and the 200 mm diameter main between Cherry Grove and the Elizabeth Métis Settlement will also cross under the Beaver River. Depending on the location of the supply point to the Elizabeth Métis Settlement the transmission main may also cross under the Redspring Creek.

The 250 mm diameter main to Glendon will cross under the Thinlake River, west of Moose Lake. The proposed transmission mains will also cross several small unnamed creeks in the area.

Alternative 1 requires a new CLRUSC pump station in Cold Lake North, as well as additional transfer pumping at the water treatment plant. At the water treatment plant, larger transfer pumps will be required. If the existing 500 mm diameter dedicated fill line to Cold Lake North is not tied in to the regional system, the transfer pumps at the water treatment plant should be operated at a pressure of approximately 550 kPa by 2032. However, if the 500 mm fill line is tied into the regional system, and acts as a third supply line to the new CLRUSC pump station, the pump head required can be reduced to a pressure of 350 kPa. At the proposed CLRUSC pump station in Cold Lake North, three pumps (300 HP each) are recommended to be installed, with an operating pressure of 700 kPa.

In addition, five booster stations are required. The first booster station will need to be located along Highway 28, east of Ardmore. The elevation of this booster station should be at approximately 540 m. It is recommended that three booster pumps (150 HP each) be installed and operated at a pressure of 700 kPa.

The second booster station will need to be located along the proposed 300 mm diameter main, east of the connection to Pelican Narrows. The elevation of this booster station should be no higher than 549 m. It is recommended that two 50HP booster pumps be installed and operated at a pressure of 700 kPa.

The third booster station will need to be located south of Moose Lake. The elevation of this booster station should be no higher than 597 m, so that the pressure on the suction side of the booster station does not drop below the minimum requirement of 140 kPa. Two 50 HP pumps are proposed for this booster station, with an operating pressure of 400 kPa.

A booster station will also be required along the existing 150 mm diameter transmission main to the Cold Lake IR 149. This booster station should be located south of Highway 28, and is only required by the 2032 development condition. Two 20 HP pumps are proposed for this booster station, with an operating pressure of 500 kPa.

A booster station will also be required along the proposed 200 mm diameter main to the Elizabeth Métis Settlement. The booster station should be located south of the proposed Beaver River crossing, at an elevation of approximately 535 m. It is recommended that two 10 HP booster pumps be installed and operated at a pressure of 450 kPa.

RPT2-0089-077-00-FINAL-090227.DOC WATER SERVICING 39 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

At Cold Lake North, a 1,000 m3 CLRUSC reservoir will be required. Since the supply from the water treatment plant will be provided in a 20 hour period to Cold Lake North, the reservoir will store the excess supply until there is demand in the system. Although the new CLRUSC reservoir was priced as a separate reservoir, depending on the location of the new reservoir the additional storage can be combined with the Cold Lake North reservoir. The Cold Lake North reservoir also requires expansion to adequately supply the City of Cold Lake, as indicated in the City of Cold Lake Water Distribution System Modelling and Assessment draft report, UMA, 2007.

Chlorine booster stations will not be required along the regional system. Each municipality will be responsible for testing the chlorine residual levels prior to distributing the water. There are no additional regional truck fills proposed at this time, as it may impact the pressure in the transmission main during operation. However, if truck fill stations are proposed then a separate reservoir and pump station will be required. These truck fill reservoirs can be filled from the transmission mains.

Figure 5.16 summarizes the ultimate flow rates and velocities, for the year 2032, in individual pipes for the recommended alterative.

5.9.3 Stage 1 Design

Stage 1 of the regional water supply system involves completion of the transmission main from Cold Lake to the Town of Bonnyville. To supply water to Bonnyville, the 500 mm diameter transmission main would need to be installed. The proposed booster station along Highway 28 would not be required at this time. However, once additional communities are added to the system the booster station will be required.

It is recommended that the proposed CLRUSC reservoir and pump station in Cold Lake North be constructed to supply the regional customers.

The infrastructure required for Stage 1 development of the recommended alternative includes a new CLRUSC pump station and reservoir located in Cold Lake North complete with 500 mm diameter transmission mains to connect the new pump station/reservoir to the existing transmission system, a 500 mm diameter transmission main to Cold Lake South, a 500 mm diameter transmission main to Bonnyville, and upgrades to the Cold Lake water treatment plant.

This reservoir will be supplied from the Cold Lake Water Treatment Plant through the twin 300 mm and 400 mm diameter transmission mains. A schematic of the stage 1 transmission system is indicated in Figure 5.17.

RPT2-0089-077-00-FINAL-090227.DOC WATER SERVICING 40 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

The capital costs for Stage 1 development are summarized in Table 5.23. The cost estimates include 35% for contingencies and 10% for engineering.

6.0 Water Treatment

6.1 General

This section discusses the existing water treatment system as well as the design criteria and options for plant expansion through the year 2032. Conceptual cost estimates are presented for the different alternatives and a preferred expansion option is recommended.

6.2 Design Criteria

Projected water demand is based on the population growth for the region and has been evaluated for a 5 year (2012) and 25 year (2032) population growth horizon. As detailed in Table 6.1, the ADD in year 2032 is projected to be approximately 19 ML/d. Applying a peaking factor of 2, the corresponding MDD was projected to be approximately 37 ML/d.

Table 6.1: Water Treatment Design Criteria

Average Day Demand Maximum Day Demand** Year ML/d L/s ML/d L/s 2006 9.50 110 18.9 219 2012* 10.9 126 21.8 252 2032* 18.6 215 37.2 430 * Based on a demand of 375 L/person/day ** Based on a peaking factor of 2

Water demands were determined using the aggregate demand from the serviced communities as described in Section 5. Demands in 2006 are based on existing water usage where projected demands of 2012 and 2032 assume a per capita water demand of 375 L/s.

6.3 Existing System Description

The Cold Lake Water Treatment Plant was upgraded in 2004 with immersed membrane modules supplied by GE Zenon. Prior to 2004, the existing water treatment plant consisted of sand filtration and chlorination. Two membrane trains of five cassettes were installed with provisional tankage for a third train. The treatment plant upgrade provided a production capacity of 22 ML/d. The addition of the third train of the same membranes would increase production by 11 ML/d. The site plan and existing layout of the existing treatment facility are shown in Figure 6.1 and Figure 6.2, respectively.

Permeate is collected in a 400 mm header feeding a clearwell located under the treatment plant. Backwash water (treated) is drawn from two pumps on the west end of the clearwell. Two separate distribution systems draw from the clearwell, a 500 mm line with two pumps feeding the Cold Lake North Reservoir, and 300 mm and 400 mm distribution lines with two pumps supplying 4 Wing Cold Lake and other reservoirs downstream of the Cold Lake meter vault.

The City is serviced by water pumped out of the Cold Lake North Reservoir, and the Cold Lake Southeast and Southwest Reservoirs (downstream of the Cold Lake meter vault).

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 59 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

6.4 Installed Membranes

The existing membrane trains consists of five cassettes, each made up of 81 modules. Every module contains over 37 m2 of membrane fibre surface area. Each membrane tank was designed to accommodate 6 cassettes so that in the event that 5 cassettes could not provide the designed output of 11 ML/d, a sixth cassette could be added. The design intent was not to provide an additional cassette worth of capacity and as such, the associated equipment may be undersized for flows beyond 11 ML/d per train. An allowance was built into the system in order to account for cleaning time (regular, maintenance, and clean in place) and integrity testing, while still providing 11 ML/d.

The City of Cold Lake has a ten year contract with GE Zenon initialized in September, 2004. Under the terms of the contract, modules can be replaced at a unit cost of $700. 810 modules were provided at the beginning of the contract.

The existing membrane trains are denoted Version 2 by GE Zenon, and Version 3 membranes are now available. Version 3 trains offer the advantage of a greater membrane fibre packing density and therefore greater water production. A 5 cassette, 81 module train of Version 3 membranes would provide 13.7 ML/d (accounting for downtime related to cleaning and integrity testing), compared to the 11 ML/d available with the Version 2 membranes. Three trains of 5 cassette Version 3 membranes would produce 41 ML/d versus the 33 ML/d available with the equivalent Version 2 membranes.

Version 3 membrane trains are of a different configuration than Version 2 membranes and it is not possible to install Version 3 membrane modules into a Version 2 frame. In order to retrofit existing Version 2 membranes, the entire cassette would have to be removed.

6.5 Water Treatment Concepts

There are a number of challenges with the existing treatment system that need to be considered when looking at long term options for the facility. In particular:

• the plant is approaching its design capacity of 254 L/s (22 ML/d), likely exceeding it by 2010, and • there is limited space within the existing structure for additional equipment, including the permeate pump and associated piping for the third membrane train.

Two water treatment alternatives were conceptually planned to provide capacity through the year 2032 and address the water treatment concerns of the current facility. Long term plant capacity can be addressed after the distribution changes and the construction of the recommended regional pumphouse. Capacity can be addressed in one of two ways, described as Long Term Alternative 1 and 2 in the subsequent sections.

The first would involve filling out the existing tankage with higher production membranes. In order to accommodate 2032 flows and the associated equipment in this scenario, a small expansion would be necessary to house the transfer pumps. The second alternative would involve the construction of a new facility adjacent to the regional reservoir. The new water treatment plant would use the existing facility as a raw water pumphouse.

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 60 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

6.5.1 Initial Pumping and Piping Modifications

Before long term expansion is considered, there are short term modifications to the existing system that are necessary as part of the regional planning recommended in Section 5 that have implications on the transfer piping leaving the water treatment plant.

As part of regionalization, a new pumphouse and reservoir are recommended. The existing 4 Wing distribution lines would be redirected to the new reservoir with treated water metered to 4 Wing, the Cold Lake reservoirs, and various other communities from the new reservoir.

6.5.2 Long Term Alternative 1

The first alternative involves filling out the existing tankage and modifying the remaining trains to accommodate 2032 demands. As the plant is approaching its existing capacity, the addition of a third membrane train and its associated equipment will be necessary by 2012. Space in the existing treatment plant is limited, and the fire pump will have to be removed in the first phase to make room for the third permeate pump. Fire flow capacity can then be provided at the future regional pumphouse.

The addition of a third membrane train (Version 3) would provide a plant capacity of approximately 36 ML/d, sufficient to meet projected demands to 2030. As long as the equipment for the third train is in place, all of the membrane modules do not need to be installed in 2012 and additional capacity can be installed as required into the third membrane frame.

Additional demand can be made up before that time by installing higher capacity trains in place of the existing trains. However, as the permeate pumps and piping were designed for 11 ML/d, the existing membrane equipment (pumps and piping) may have to be replaced if a retrofit were to occur.

In conjunction with the capacity expansion, the transfer pumping would have to be upgraded to provide the necessary capacity for flows through 2032. As there is limited space within the existing building, a small addition would have to be built with an associated pumpwell off of the northwest wall. Three new transfer pumps would be installed and connected to distribution piping in the existing facility. As part of the initial piping modifications, the distribution piping would be sized and oriented to allow the future pumping addition.

It will be difficult to accommodate flows beyond 2032 in the existing facility as there would be limited further expansion capability. In order to increase capacity, another building addition would be necessary (towards Cold Lake), or a new treatment plant would have to be built. An analysis of these options is not part of the scope of the present project and should be undertaken when appropriate. However, allowances for a building expansion towards the lake would be prudent as part of the present expansion if Alternative 1 were to be pursued.

6.5.3 Long Term Alternative 2(a)

The second alternative would see a new water treatment plant constructed on the same site as the future regional pumphouse and reservoir. The new facility would be designed to accommodate flows through 2032 and beyond using the same general design as the existing water treatment plant, but with more space for the existing equipment and provisions for expansion beyond 2032.

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 61 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

If a new water treatment plant were built, the existing plant would serve as a pumphouse and raw water reservoir. Raw water would be pumped to the water treatment plant using the new lines to the recommended reservoir beside the Cold Lake North Reservoir. The water treatment facility would be tied into both the regional reservoir and the Cold Lake North Reservoir.

The treatment plant would be designed for a capacity of 40 ML/d using the same configuration and tankage as the existing plant, with provisions made to expand the plant further. Existing pumps and water treatment equipment (including membrane cassettes) would be transferred to the new facility were possible.

The timing of construction of the new treatment plant needs to be carefully considered as the City must meet the MDD during construction and commissioning. If demands allow, the option exists to build a new treatment plant before the addition of the third train. As the existing capacity will likely be reached by 2012, a new facility would have to be online by that time if additional capacity is not added to the existing treatment plant.

This timing would negate the need to upgrade the existing water treatment plant to meet short term demand only to have to abandon it in the future. Furthermore, it would allow the phased relocation of the existing membrane equipment. A new membrane train would be installed in the new water treatment plant, allowing each of the existing trains to be transferred one at a time while maintaining adequate treatment capacity.

6.5.4 Long Term Alternative 2(b)

A variation of the second alternative involves modified timing, as it may not be possible to construct a new water treatment plant before the addition of membranes is necessary. Construction would be deferred until after additional membranes are put in place. Capacity could be installed in one of two ways, with a third membrane train, or the addition of modules in the existing two trains.

If incremental capacity is added to the existing system, construction of a new treatment plant could be delayed to the point when demand exceeds the additional installed capacity. This will involve the addition of a sixth cassette in one or both of the existing tanks. The cassettes would operate with lower production (fewer modules) than the existing cassettes while fitting within the limits of the existing pumping and other equipment. In order to pursue this option, the capacity of the permeate pumps and piping of each train will have to be evaluated.

If a full treatment train is put in place in the short term, construction of a new water treatment plant could be delayed until the capacity of the transfer pumps is reached. At that time, and if Alternative 1 is not explored, a new water treatment plant will be necessary. However, to maintain sufficient water supply, a fourth membrane train may have to be installed in the new treatment plant so that the existing trains can be transferred without compromising the ability to provide MDD flows.

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 62 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

6.5.5 Redundancy

In both alternatives, the upgrading concepts are planned so that there is one redundant transfer pump and the ability to achieve MDD with full membrane treatment capacity. If a membrane train is out of service, potentially due to a permeate pump failure, the water treatment plant will be capable of achieving ADD production (at a minimum). Rather than providing a redundant membrane train, it would be more cost effective to have spare equipment available so that any service disruption can be dealt with quickly.

After the installation of a third membrane train, the water treatment plant will have close to a fully redundant train, depending on how many modules are placed in the train. As demand grows, this redundancy will be reduced until 2030, when it is projected that the MDD capacity will be reached. It may be possible to temporarily push the membranes in service to operate at a higher flux to meet demands. However, operating at a higher flux will result in a faster rate of fouling and may require more frequent cleaning.

6.6 Conceptual Cost Estimates

6.6.1 Operations and Maintenance Costs

Operations and maintenance costs associated with the water treatment plant include utility and chemical costs, membrane, mechanical, and instrumentation maintenance, operations labour, and indirect costs (including insurance, overhead, water quality testing, and vehicles). Ultimately, these will not differ between options as the chemical, power, and maintenance costs will be proportional to the amount of water produced. However, in order to provide life cycle costs of the two alternatives, the operations and maintenance costs are considered. Including utilities, chemicals, maintenance, labour, and overhead, the operations and maintenance costs were estimated to be $1,200,000 per year ($800,000 operations and $400,000 maintenance).

6.6.2 Capital Costs

Table 6.2 summarizes the present worth cost estimates for each of the alternatives, including capital costs but excluding operation and maintenance (O&M) costs. As the operations and maintenance costs of both options are assumed to be equal, they have no impact in an overall cost comparison. Preliminary cost estimates are detailed in Appendix D.

Table 6.2: Water Transmission System Cost Estimate Summary

Alternative Present Worth Capital Present Worth O&M Total Present Worth Alternative 1 $5,270,000 $ - $5,270,000 Alternative 2 $8,258,000 $ - $8,258,000 Notes: 1. Costs based on upgrades taking place in 2012 and 2030 2. Present worth values calculated using a discounting factor of 4% 3. O&M costs not considered as they are equal in both cases

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 63 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

The cost estimates are presented in present worth dollars and include the addition of three new 13.7 ML membrane treatment trains (one in 2012 and two more in 2030). Alternative 1 costs include the initial piping and pumping modifications, and the installation of one membrane train in 2012, followed by a building addition, new transfer pumps, and two membrane trains in 2030. It should be noted that the building addition and the new transfer pumps may be necessary before 2030.

The Alternative 2 estimate considers the immediate construction of a new facility (Alternative 2a), transfer pumping to the new reservoir and the Cold Lake North Reservoir, and new chemical addition equipment. For both alternatives, the plant capacity will be approximately 41 ML/d, providing enough production to meet the projected demands of 2032.

The costs per membrane train, at approximately $1,750,000 each, include all of the associated equipment (pumps and piping) and constitute the majority of the costs of both alternatives. Without the replacement of the second and third membrane trains after 2030, the costs of Alternative 1 and Alternative 2 come to $3,197,000 and $6,186,000, respectively.

It may be possible to significantly reduce the costs of the second alternative if membrane equipment could be transferred to the new water treatment plant (without service disruption). However, these potential cost savings may be negated by having to replace the trains for other reasons beyond 2030, when the retrofits of the two existing trains of Alternative 1 will take place.

6.7 Evaluation of Alternatives

The first alternative offers the advantages of being able to use the existing facility without the disruption of constructing and costs of a new facility. Furthermore, after the installation of the third membrane treatment train, the treatment plant would have the membrane capacity to meet the regional projected MDD to 2030. Before that time, demand projections and membrane treatment technology can be reassessed, ensuring the best option is selected. The advantages and disadvantages of the two development options are presented in Table 6.3.

Table 6.3: Comparison of Upgrading Options

• Alternative 1 Alternative 2 y Use existing facility and tankage y Eliminate space limitations y Lower cost y Better site conditions y Only have to install one membrane train before y Provide better plant layout and access to 2030 equipment

Advantages y Ability to reassess flows before major expansion y Have room for expansion beyond 2032 y Reduced environmental impact y Reduced pumping costs y Poor mobility around existing and future equipment y Have to convert a relatively newly refurnished plant not addressed to a raw water pumphouse y Further expansion beyond 2032 difficult and may y May have to purchase 4th membrane train before it ultimately have to build a new facility is actually necessary y Timing may pose a challenge Disadvantages y Higher cost

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 64 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

The disadvantage of the first alternative is the expense involved in replacing the existing membrane trains within the current tanks, necessary beyond the projected demands of 2030. The production increase of replacing an existing train with one of higher fiber density is far less than if a new train was simply added in a fourth tank. The limited cost savings to do this make it difficult to justify retrofitting the existing membrane tanks. However, the membrane trains will be over 20 years old and the equipment may have to be replaced regardless of the selected upgrading option.

The primary advantage of Alternative 2 is the elimination of space concerns at the existing sites, while providing space for expansion beyond 2032. It would also reduce pumping costs as the transfer pump expansion in 2032 would not be necessary.

6.8 Recommended Water Treatment Alternative

The two options available to the Commission involve either constructing a new water treatment plant or extending the life of the existing facility through membrane and transfer pumping upgrades. Both alternatives meet the necessary requirements for the future development conditions within the study area.

Although it may be ultimately necessary to build a new facility or construct a major addition to the existing plant, these upgrades are not necessary until flows beyond those projected in 2032 are experienced and are therefore not recommended at this time. With the addition of a membrane train and associated equipment capable of supplying a flow of 13.7 ML/d, the plant is capable of meeting the MDD until 2030. Beyond that time, it will be necessary to replace both existing trains with higher density membranes (or expand the treatment plant).

Due to the cost savings over the planning horizon and the ability to use the existing facility and equipment, Alternative 1 is the recommended water treatment concept. Implementing Alternative 1 gives the Commission the greatest long term flexibility, provides the potential for cost savings over the long term, and satisfies the short and mid-term demands at a lower cost than Alternative 2. It also allows the Commission the ability to re-evaluate the water demands and the available treatment alternatives before a major plant expansion is undertaken.

6.9 Conceptual Design of Preferred Alternative

Demands are expected to exceed the existing plant capacity by 2012, and the installation of a third membrane train (with a capacity of 13.7 ML/d) is recommended at that time. With its installation, projected 2012 demands will be easily met. Retrofitting the existing membrane tanks will have to be completed by 2030.

Modifications to the transfer pumping and the addition of a building expansion will be necessary as demands increase. Depending on the supply pressure needed from the water treatment plant, the building expansion and additional transfer pumps may need to occur as early as 2019 (550 kPa) and as late as 2030 (350 kPa).

The proceeding sections outline the conceptual design of the preferred alternative for 2012 and 2032. Design changes for 2012 and 2032 are shown on Figure 6.3 and Figure 6.4, respectively.

RPT2-0089-077-00-FINAL-090227.DOC WATER TREATMENT 65 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

6.9.1 Design for 2012

Although the building addition and new transfer pumps are not necessary for demands through 2012, piping and pumping modifications would have to take place to accommodate their future addition (and to provide sufficient pumping through 2032). These should be done at the same time as the installation of the third membrane train and removal of the fire pump, and after the recommended construction of the new regional pumphouse and associated fill lines. The upgrading sequencing for the preferred alternative includes:

1. The removal of the fire pump and installation of the third membrane train, associated piping and permeate pump.

2. The addition of a 600 mm header to connect to the future transfer pumps located in the building expansion (requiring modification to the existing 500 mm header).

Note: While work is being done on the 500 mm header, the existing transfer pumps on the 350 mm line will act as the fill pumps to the regional pumphouse.

3. A new transfer pump would then be installed on the modified 500 mm line and used to fill the new pumphouse so that the existing transfer pumps on the 500 mm line can be removed.

4. Once the new transfer pump is online on the 500 mm header and the others are removed, the existing 4 Wing transfer pumps would be relocated to the 500 mm header.

Removal of the 4 Wing transfer pumps on the 350 mm line in addition to the removal of the fire pump would provide the necessary space for the permeate pump of the third membrane train while accommodating the transfer pumping through 2032. The 2012 transfer pump schematic is shown in Figure 6.5.

6.9.2 Design for 2032

New transfer pumps will be necessary for 2032 flows sometime after the installation of the third membrane train as demands require (to maintain the ability to operate with one pump out of service). As there is limited space in the existing facility, an addition will be constructed to house three new transfer pumps and a pumpwell. The new transfer pumps will be tied into the 600 mm header put in place during the 2012 piping modifications. The 2032 transfer pump schematic is shown in Figure 6.6

Additional membrane capacity will be necessary by 2030, accomplished by replacing one of the existing trains with higher capacity equipment. If 13.7 ML/d replaces one of the existing trains in 2030, the same will have to be done to the other existing train in 2034.

7.0 Cost Estimate and Implementation Plan

7.1 Cost Estimates

The cost estimates for the recommended servicing concept is summarized in Table 7.1. The costs for the refined water servicing Alternative 1 and water treatment Alternative 1 are included.

Alternative Present Worth Capital Present Worth O&M Total Present Worth Water Servicing (Alternative $93,904,000 $25,563,000 $119,467,000 1 Refined) Water Treatment $5,270,000 $13,405,000 $18,675,000 (Alternative 1) TOTAL $99,174,000 $38,968,000 $138,142,000

The costs for the proposed Stage 1 system are summarized in Table 7.2.

Table 7.2: Stage 1 Cost Estimate Summary

Capital Cost ($) Development Water Servicing Water Treatment Total Stage 1 $61,204,000 $3,228,000 $64,432,000 Table----- 7.3 summarizes the estimated cost per person to service each of the expansion communities. Per capita cost sharing was based on the cost estimates for the recommended servicing concept. The costs are based on the capital costs, not present worth costs, and do not include tie-in or storage costs for the individual municipalities. Costs were split between communities based on a percentage of total flow through the pump or transmission main.

Since the existing system is adequate to service the existing communities through 2012, costs for 2012 were allocated to only the expansion communities. However, the 2032 costs were allocated between both the existing and expansion communities based on the flow percentages.

The breakdown of the cost allocation is summarized in Tables D.6 to D.12 in Appendix D.

The costs for Cold Lake IR 149A and IR 149B do not include the tie-in to the Cold Lake North distribution ----system.

Average cost per serviced capita.

As indicated in Table 7.3, the per capita service costs range from $160 to $53,690; as a result it may not be economically feasible to service some of the communities with a high per capita cost.

The allocated costs were used in the development of the utility governance model, completed by CORVUS Business Advisors. The report detailing the evaluation of the current governance structure as well as alternative governance structures is included in Appendix E. At the time of the development of the utility governance model, Alternative 2 was the preferred water servicing alternative. Therefore; the costs indicated in Appendix E are based on the costs for Alternative 2. However, this will not have a significant impact on the recommended governance model.

As part of the Alberta Water for Life Strategy, Alberta Infrastructure will fund a percentage of the capital costs for regional water supply systems. Based on the project eligibility and funding levels for new pipelines and treatment upgrades from the AMWWP Regional Systems Initiative and Water Strategy Initiative, the following funding percentages may be applicable:

• Pipelines for new regional systems (water or wastewater) are funded up to 90%. • Pipeline capacity for future extensions to the pipeline to additional regional customers may be requested by the Province and would receive up to 100% funding. • Upgrades required for new customers at a commission-owned plant would be funded up to 100%.

Upon review of the regional concept, Alberta Infrastructure will confirm the funding percentages. It is important to note that funding percentages are impacted by population projections and water consumption rates, and funding levels are very specific to each individual case.

7.2 Implementation Plan

The first stage of the project is to complete the supply line to Bonnyville, due to the aging condition of the existing Bonnyville water treatment plant. For the first development stage, the booster station along Highway 28 will not be required. However, once the additional communities are connected to the system the booster station will be required.

It was assumed that all of the expansion communities would be serviced by 2012; therefore, the majority of the proposed pipes are required by 2012.

For the recommended water servicing alternative, some of the proposed pumps can be installed in stages. The required pump upgrades at the Cold Lake Water Treatment Plant are not required until 2032. At the proposed CLRUSC pump station in Cold Lake North, two pumps are required by 2012; however, the third pump is not required until 2032. The proposed booster stations for Cold Lake IR 149 and the Elizabeth Métis Settlement are not required until the 2032 development condition. The detailed staging for the recommended alternative is indicated in Table 5.21 in Section 5.9.2.

If Frog Lake is included as a future expansion community, the proposed 200 mm diameter transmission main from Cold Lake to the Elizabeth Métis Settlement would need to be upgraded to a 250 mm diameter main, and the pumping at the booster station would need to be increased.

Each creek crossing must be in compliance with the requirements of the Code of Practice for Pipeline Crossings under the Water Act.

8.0 Utility Governance Model

8.1 General

An evaluation of the current governance structure of the Cold Lake Regional Utility Services Commission (CLRUSC) was undertaken by CORVUS Business Advisors. In addition, alternative governance structures were examined for the potential expansion of the CLRUSC. The intention of this review is to provide the CLRUSC with:

• An understanding of the governance dynamics associated with potential expansion of CLRUSC membership as a result of regional system expansion; and • A recommended governance structure / workings of the CLRUSC Board and implementation path to bring about recommended governance changes, should the CLRUSC wish to pursue a regional system expansion.

8.2 Existing CLRUSC Members

The current CLRUSC is comprised of seven board members:

• City of Cold Lake (4 members) • 4 Wing Cold Lake (1 member) • Cold Lake IR 149 (1 member) • M.D. of Bonnyville (1 member)

The regional water system expansion presents significant opportunities and issues to existing CLRUSC members. The CLRUSC determines the conditions under which membership might be extended; therefore, the CLRUSC must be fully satisfied with the conditions under which they are prepared to extend services and under which they are willing to allow new member communities onto the CLRUSC board. Some of the issues identified by the existing CLRUSC members that would need to be addressed are summarized below:

• Environmental impact of regional expansion • Financial impact on existing CLRUSC member communities • Clear understanding of grant support • Commitment from new members on capital requirements • Future control and decision making.

8.3 Recommended Governance Structure

As a first step in moving forward with the regional water system expansion, the CLRUSC needs to first consider the steps that would be taken and which communities should be serviced in the first stage of expansion. From a practical and near-future perspective, it is likely that only one new member community has the potential to participate in the water system expansion and become a member of the CLRUSC; the Town of Bonnyville. The participation of the Town of Bonnyville is critical if the regional water expansion is to proceed. With the expansion of the Hamlet of La Corey, consideration of receiving water services

RPT2-0089-077-00-FINAL-090227.DOC UTILITY GOVERNANCE MODEL 76 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

from the CLRUSC should be deferred until the initial service to the Town of Bonnyville has been constructed.

For the first stage of expansion, it is recommended that the board remain at seven members with two of the current positions from the City of Cold Lake shifted to the Town of Bonnyville, such that both the City and the Town have two members. At the time of ultimate expansion, it is recommended that the board be expanded to include eleven members, with one additional position given to the following communities: the Village of Glendon, the Summer Village of Bonnyville Beach, the Summer Village of Pelican Narrows, and the Elizabeth Métis Settlement.

With regards to future decision-making, the model currently used by the Greater Vancouver Regional District (GVRD) is workable for the expanded CLRUSC. GVRD decision-making is usually made using a one-member, one-vote model (consensus approach). However, for any financial decisions a member can motion for a weighted decision. If the motion is seconded, a weighted decision voting process in undertaken. For the CLRUSC, it is recommended that the weighted vote be based upon population.

8.4 Implementation Plan

There are various actions that need to be undertaken before the regional system expansion can move forward and the CLRUSC can consider any governance or membership changes. A summary of the implementation tasks is provided below:

• Create a regional system forum • Create a Chief Administrative Officer position • Environmental impact study of Cold Lake • Staging plan for Stage 1 construction • Grant information • Province carry oversizing costs • Make decision on moving forward with Stage 1 • Obtain financial commitment of Stage 1 participants • Obtain approval from the Minister to extend CLRUSC debt limits (optional) • Request changes to regulation for amended CLRUSC structure and roll over of Stage 1 assets into the CLRUSC • Draft CLRUSC bylaws governing voting, quorum, etc.

The complete report on the utility governance model is provided in Appendix E.

RPT2-0089-077-00-FINAL-090227.DOC UTILITY GOVERNANCE MODEL 77 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY

9.0 Conclusions and Recommendations

9.1 Growth Scenarios

• The population projections developed have been based on historical population trends, current populations and economic activity. These population projections impact the timing of system improvements and should be reviewed on a regular basis. • 5 year and 25 year population targets were developed. • The planning targets represent more than a doubling of the regional population by 2032, from the current population of around 25,000 to over 50,000.

9.2 Water Servicing

• The existing system was analyzed based on the existing water consumption data. • It is recommended that the future system be designed for a composite water consumption rate of 375 L/capita/day (average day demand) to correspond with the provincial average. • The transmission system was sized for two times the average day demand. • For each alternative, it is recommended that the CLRUSC system be separated from the City of Cold Lake distribution system where possible. However, it is recommended that Cold Lake IR 149A and Cold Lake IR 149B be supplied from the Cold Lake North distribution system. • It was assumed that all expansion communities would be serviced by 2012. • For all of the alternative water servicing concepts, it is proposed that there be a dedicated fill line from the Water Treatment Plant to a new CLRUSC reservoir/pump station located in Cold Lake North. A 1500 m3 reservoir will be required. This pump station will supply all of the regional customers, with the exception of Cold Lake North which has a dedicated fill line from the Water Treatment Plant. • Four water servicing alternatives were developed. For each alternative, the servicing to areas west of Bonnyville is the same. • Alternative 1 includes upgrading the existing transmission main from Cold Lake to Fort Kent and extending the main to Bonnyville. The total length of pipe required is 147 km, and 2 booster stations are required. • Alternative 1a includes the same servicing concept as Alternative 1, with an additional connection from Cold Lake to La Corey. The total length of pipe required is 183 km, and 2 booster stations are required. • Alternative 2 includes the installation of a new transmission main from Cold Lake west to La Corey, then south to Bonnyville. The total length of pipe required is 150 km, and 2 booster stations are required. • Alternative 3 includes the installation of a new transmission main from Cold Lake south to the Elizabeth Métis Settlement, then west to Bonnyville. The total length of pipe required is 165 km, and 3 booster stations are required. • Present worth costs were determined for each of the alternatives, including both capital costs and operation and maintenance costs. The cost estimates include 35% for contingencies and 10% for engineering and overhead, and are summarized in Table 9.1.

RPT2-0089-077-00-FINAL-090227.DOC CONCLUSIONS AND RECOMMENDATIONS 78 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

Table 9.1: Water Transmission System Cost Estimate Summary

• Alternative 1 is the recommended water servicing concept since it is the most cost effective alternative. • The initial population targets were determined through analysis of historical data and discussions with the steering committee. Subsequently, Alberta Transportation indicated that an annual growth rate of 2.5% should not be exceeded in the design of regional systems. Therefore, the population projections for the Town of Bonnyville and the Village of Glendon were reduced to 2.5% annual growth and the flow rates were adjusted accordingly. • Refinements were considered for the Alternative 1 design, to account for the reduced flow rates and to provide the most cost effective alternative. The proposed 600 mm diameter transmission main was reduced to 500 mm diameter, and the proposed pump station in Cold Lake South was eliminated. However, additional booster stations are required. • The total capital cost and present worth costs for the recommended alternative are $116,692,000 and $119,467,000, respectively.

9.3 Water Treatment

• Demands are expected to exceed the existing plant capacity (22 ML/d) by 2010, and a third membrane train (with a capacity of 13.7 ML/d) should be installed at that time. With its installation, projected 2012 demands (21.8 ML/d) will be easily met. • For long-term servicing, two alternatives were considered. Alternative 1 involves filling out the existing tankage and modifying the remaining tanks to accommodate 2032 demands. • Alternative 2 involves the construction of a new treatment plant on the same site as the future CLRUSC pump station and reservoir in Cold Lake North. The existing water treatment plant would be used as a pumphouse and raw water reservoir. • Although it may be ultimately necessary to build a new facility or construct a major addition to the existing plant, these upgrades are not necessary until flows beyond those projected in 2032 are experienced. Therefore, Alternative 1 is recommended. • Retrofitting the first and second existing membrane tanks and replacement of the existing membranes with new higher density membranes (with a capacity of 13.7 ML/d) will have to be completed by 2030 and 2034, respectively, in order to meet the projected maximum day demand in 2032 (37.2 ML/d). • Modifications to the distribution pumping and the addition of a building expansion will be necessary before any new capacity is added above the third membrane train.

9.4 Cost Estimates and Implementation Plan

• For the recommended alternatives, refined water servicing Alternative 1 and water treatment Alternative 1, the total capital cost is $126,368,000, and the total present worth cost, including operation and maintenance, is $138,142,000.

RPT2-0089-077-00-FINAL-090227.DOC CONCLUSIONS AND RECOMMENDATIONS 79 COLD LAKE REGIONAL UTILITY SERVICES COMMISSION REGIONAL WATER SUPPLY FUNCTIONAL PLAN & FEASIBILITY STUDY AECOM

• Per capita costs were developed for each of the communities, based on the estimated capital costs. The costs were split between communities based on a percentage of total flow through the pump or transmission main, and were based on recommended alternatives. • Table 9.2 summarizes the estimated cost per person to service each of the communities. Table 9.2: Cost Sharing Summary

• It may not be economically feasible to service some of the communities that have high per capita costs. • Stage 1 of the regional system expansion involves the addition of the Town of Bonnyville. To service the Town, the construction of the 500 mm diameter transmission main would be required, as well as the new CLRUSC pump station and reservoir, and the water treatment plant upgrades recommended for 2012. The capital cost for Stage 1 is $64,432,000, including both water servicing and water treatment.

9.5 Utility Governance Model

• The current CLRUSC is comprised of seven board members. • The CLRUSC determines the conditions under which membership might be extended; there are some issues identified by existing CLRUSC members that would need to be addresses prior to expansion. • As a first step in moving forward with the regional water system expansion, the CLRUSC needs to first consider the steps that would be taken and which communities would be serviced during Stage 1 of the expansion. • For Stage 1, it is recommended that the board remain at seven members, with two positions given to the Town of Bonnyville. For the ultimate expansion, it is recommended that the board be expanded to eleven members, with one position given to each additional community. • For decision making processes, it is recommended that a one-member, one-vote model be used; however, for financial decisions the board will have the option to undertake a population weighted voting process.
