I. INTRODUCTION

A. Purpose The purpose of this facility plan is to develop a comprehensive Collection System Evaluation to guide sewer collection system improvements to be pursued by the City of Cassville over the next several years. This facility plan presents an analysis and evaluation of previous wastewater system reports and smoke-testing results, recent sewer line videoing and flow monitoring, Public Works Department maintenance logs, geographical information system (GIS) mapping, and a funding strategy to prioritize and schedule the recommended actions stemming from the evaluation.

B. Scope Preparation of this facility plan included the following steps:

1. Review of the City’s previous wastewater system reports;

2. Review of the City’s sewer system GIS mapping;

3. Review of previous smoke testing results;

4. Review and analysis of recent closed-caption television (CCTV) sewer line videos;

5. Review of recent Public Works Department maintenance logs and activities;

6. Review of City pump station information;

7. Discussion of sewer system issues with Public Works staff, including coordinating additional inspections;

8. Development of a prioritized spreadsheet of recommended improvements based on the review, analysis, and evaluation of the data;

9. Development of cost opinions and a funding strategy for the City to complete the recommended improvements and actions over the next several years.

C. Existing Conditions The City of Cassville’s existing wastewater system consists of a mostly gravity-flow collection system with only one lift station that serves a very small area of the system, and a mechanical wastewater treatment plant (WWTP) with an adjacent overflow lagoon for wet-weather flow storage. The collection system consists of approximately 171,325 feet of gravity mains, 640 manholes, 34 lampholes, and 953 feet of force main from one lift station in the northern portion of the system. The gravity sewer mains range in size from 6” to 24” in diameter.

Project No. 014-2994 1 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

A significant portion of the gravity lines are 8-inch vitrified clay pipe (VCP). Much of the original collection system was constructed prior to 1940, with portions of the original system still in use today. Newer lines have been constructed with conventional polyvinyl chloride (PVC) pipe. The older manholes were constructed with brick and mortar, with newer manholes being pre-cast or poured-in-place concrete.

The mechanical WWTP, located along the northeast edge of town, was initially constructed in 1979 and took the place of the stabilization pond that once served the community. The original stabilization pond now serves as a wet-weather extraneous flow basin. The WWTP, which discharges to Flat Creek in Barry County, currently utilizes an aeration basin with a selector basin and four clarifiers followed by chemical phosphorus removal with disc filtration and then ultraviolet disinfection. For sludge storage, the City uses an aerated sludge holding tank. All of the wastewater that enters the WWTP must be pumped by a main influent lift station (capacity 4.8 MGD) at the head of the plant.

The permitted WWTP design population equivalent is 8,630 with a design flow of 1.1 million gallons per day (MGD). Per the City’s current operating permit, which runs from March 2011 through March 2016, the actual flow through Outfall #001 is listed as 0.925 MGD, and the design sludge production is 115 dry tons/year. Discharge from Outfall #002 associated with the 18-acre stabilization pond is no longer authorized and must be reported as an emergency bypass. Ideally, wet-weather flows that are diverted to the storage pond are only to be stored until treatment capacity is available at the mechanical WWTP.

Several hundred feet of gravity sewer main runs adjacent to Flat Creek, which cuts through the city and is subject to variable creek levels, high groundwater conditions, and flash flooding. Due to the nature of the underlying aquifer, high creek levels during wet-weather events temporarily cause a rise in the regional water table that can last for weeks after the creek floodwaters recede. During these periods of wet-weather and persistent high groundwater levels, the collection system experiences excessive inflow and infiltration (I&I) into the sewer lines, which can lead to surcharging manholes throughout town and very high flows to the WWTP.

The WWTP’s hydraulic capacity is approximately 1.2 MGD. Incoming flow in excess of this capacity is temporarily stored in the adjacent stabilization pond (lagoon) until it can be pumped back through the plant for full treatment. However, because excess flow diversion to the lagoon occurs after the WWTP influent lift station, this flow must be pumped a second time to receive treatment through the plant. During major wet-weather events, the lagoon fills up to capacity and the plant operators must open the discharge valve to release water from the lagoon through Outfall #002.

Under previous operating permits, the City was permitted to discharge from Outfall #002 as long as the effluent quality met the discharge limits for this outfall. However, a 2010 revision to Missouri Department of Natural Resources’ (MoDNR) effluent regulations now prohibits wastewater discharges that bypass secondary treatment. Accordingly, discharge from Outfall #002 is no longer authorized.

Project No. 014-2994 2 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

In March of 2011, the City of Cassville signed a Voluntary Compliance Agreement (VCA) with MoDNR requiring the City to report any future discharges from the lagoon as a “bypass” and to develop a Bypass Elimination Plan (BEP) to outline how the City plans to reduce wet-weather flows and eliminate bypasses from the lagoon. A BEP report was completed in July of 2012 and subsequently submitted to MoDNR for review. The BEP report included a summary of the wastewater system, results from flow-monitoring several locations in the collection system, comparison of dry-weather and wet-weather flow conditions, analysis of lagoon storage capacity, presentation of alternatives for eliminating treatment plant bypasses, proposed collection system upgrades, and a recommended sewer improvements project based on estimated quantities derived from the limited information available. The report was approved for implementation by MoDNR.

The drought conditions experienced in 2012 showed that an increase in collection system piping size was not needed, but rather a reduction in the extraneous I&I flows in the system was warranted. However, the amount of data that was available for evaluation during the development of the BEP report was not sufficient enough to recommend detailed sewer rehabilitation improvements to specific collection system lines. As a result, a collection system rehabilitation schedule that could be associated with a funding strategy was not developed as part of the BEP. Accordingly, this facility plan builds upon the 2012 BEP report by analyzing additional data and establishing specific rehabilitation efforts for collection system lines to be associated with the City’s anticipated rehabilitation budget over the next several years.

II. GENERAL INFORMATION AND PLANNING AREA

A. Identification The name and mailing address of the Publicly Owned Treatment Works (POTW) system continuing authority is:

City of Cassville 300 Main Street Cassville, MO 65738 Mr. Bill Shiveley, Mayor Mr. Steve Walensky, Public Works Director

Mayor Shiveley and Mr. Walensky can be contacted at City Hall, phone number 417.847.4441. The City’s POTW is operated under Missouri State Operating Permit (MOSP) MO-0042579 as part of the National Pollutant Discharge Elimination System (NPDES) and is regulated at the state level by MoDNR, whose central office is located in Jefferson City, Missouri. Regional MoDNR regulatory authority is provided by personnel staffed in the Southwest Regional Office (SWRO) of MoDNR, located in Springfield, Missouri.

B. Planning Area The planning area for this facility plan includes the area served by the City of Cassville’s existing wastewater collection system, shown in Exhibit 1. In general, this area is representative of the City’s incorporated limits, which encompasses approximately 3.22 square miles. Only two (2) notable collection system lines are located outside of the incorporated city limits boundary – one extends north to the Crowder College campus and the other extends northeast to the WWTP. The City currently has no definitive plans to expand its sewer system service area.

With a 2010 United State Census population of 3,266, the City of Cassville acts as a regional hub situated between the larger communities of Joplin, Missouri at forty-five (45) miles (2010 census population of 50,150); Springfield, Missouri at forty-eight (48) miles (2010 census population of 159,498); Rogers, Arkansas at thirty (30) miles (2010 census population of 55,964); and Harrison, Arkansas at fifty-one (51) miles (2010 census population of 12,943). This has resulted in the City having five (5) state highways, a uniquely high number relative to size. These include State Highways 37, 76, 86, 112, and 248.

C. Topographic, Geological, Soil, and Climate Characteristics of Planning Area 1. Topographic Barry County experiences a high elevation of over 1,500 feet USGS along a plateau just west of the service area extending from Washburn to just south of Purdy. The lowest elevation of the county is at the water level of Table Rock Lake, which has a normal surface elevation of 915 feet. The high elevation ridge in the county divides the Missouri River and White River drainage basins, with Cassville being located within the latter. The general slope of the planning area

Project No. 014-2994 4 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

and surrounding land is towards Flat Creek in the center of town where the elevation then drops off towards the northeast as Flat Creek drains into Table Rock Lake.

This unique drainage feature is why Cassville has earned the nickname “The City of Seven Valleys.” Each valley carries with it a significant area of surface water runoff that drains to Flat Creek. Utilizing maps of Barry County creeks, the estimated area of rainwater drainage is approximately forty-five (45) square miles. This large drainage area has contributed to frequent flooding events as the city is built up along and around Flat Creek’s normal flow level. With severe flooding causing the water level in Flat Creek to breach its banks by several feet, a large portion of Cassville has been placed in the Federal Emergency Management Agency’s (FEMA) 100-year floodplain.

2. Geology & Soil The soils and topography in Barry County are influenced to a great extent by many different geologic formations. From the oldest to the youngest, these formations are the Jefferson City- Cotter, Chattanooga, Compton, Pierson, Elsey-Reed Springs, Burlington-Keokuk, Hindsville, Batesville, Fayetteville, and Hale. The formations are mainly composed of limestone rock which greatly contributes to the karst nature of the area. Karst landscapes are created by easily dissolvable bedrock, resulting in cracks, caves, fissures, and sinkholes. These open geologic features more easily permit water conveyance, which can lead to high groundwater levels and higher degrees of erosion. The soils in the area are readily excavated for pipelines and are compatible with most commonly used piping materials.

3. Climate Cassville’s service area experiences a moderate climate that is similar to that of the county as a whole. Cassville has a National Climate Data Center recording center operated in cooperation by the National Weather Service and National Oceanic and Atmospheric Administration (station ID #231383). Based off of compiled data from over one hundred years of recordings, Cassville experiences a moderate climate with an average high temperature in summer of 87° F and in winter of 48° F, with a record high of 108° F on August 4, 2011 and a record low of -25° F on December 22, 1916. The City experiences an average yearly rainfall of just under 45 inches, which is well distributed throughout the year.

III. PLANNING PERIOD AND POPULATION PROJECTION

A. Planning Period In order to comply with the anticipated schedule associated with the VCA between the City of Cassville and MoDNR, a ten-year planning period was considered in regards to growth, flows, and infrastructure improvements. While this planning period was applied in consideration of developing recommendations, satisfying compliance agreements, and securing the funding needed to meet the objectives of the City’s desired rehabilitation schedule, it is not indicative of the design life of the existing wastewater system or of the improvements recommended. The recommended improvements are expected to have a 50-plus year design life, and are based on the conclusion that existing collection system rehabilitation and compliance with the VCA takes precedence on the planning schedule, rather than long-term population growth and base flow increases.

B. Population Projection Cassville was incorporated in 1846 and is currently listed as a “4th Class” city by Missouri Roster. Unlike many small cities throughout southwest Missouri, Cassville has established itself as a hub of commerce for neighboring communities, thus relieving itself from the dependence on individual businesses. Though employers come and go over the decades, Cassville has shown a resilience to population growth rate variances and has continued to increase in size steadily since 1900. Historical consistency helps increase the accuracy of the growth projections calculated for the 10-year planning period.

The yearly growth rates for the entire recorded history from 1900 to 2010 were calculated and averaged to derive the projected growth rate. Additionally, recent data was taken into consideration as factors affecting population can change completely with over a century of data. The two averages calculated out to be very similar, 1.4% for the entire span of data and 1.35% for the recent four (4) census counts. Accordingly, 1.4% annual growth was used to project future populations for the City. A graphic representation of the historical and projected populations can be found in Figure III-1. The projected planning area population for the year 2026 is 4,080.

IV. EXISTING FACILITIES ANALYSIS

A. Existing Collection System

1. Collection System Description and Inventory The sanitary sewer collection system for Cassville primarily consists of VCP and PVC gravity lines, along with one force main from the Sherwood Forest lift station. The system is divided into seven basins based on geographical and man-made barriers. Each basin has an identification letter associated with it and, in the case of Cassville, so also does the main trunk line, which serves as the interceptor sewer to convey wastewater to the WWTP. The basin identifications are arbitrarily labelled “A” through “G”, with Basin G being the main trunk line running form the newest industrial developments in the southwest to the treatment plant in the northeast portion of the service area. The Sherwood Forest lift station and associated force main are located within Basin B in the northwest portion of the City. In total, the service area has approximately 171,325 linear feet of gravity line and 953 of force main. Providing access to the sewer lines are approximately 640 manholes and 34 lampholes, which the City has incorporated into a sewer system GIS. A map of the service area can be found in Exhibit 1 and a map of the basins can be found in Exhibit 2. The following is an inventory of the collection system by basin based on current mapping data:

2. Previous Collection System Evaluation and Findings

a. General Inflow and Infiltration Findings by Public Works Staff The effects of system deficiencies are most visible at the Cassville WWTP during and following heavy rain events. As the ground becomes saturated, defects in the collection system allow rainwater to enter in the form of inflow and infiltration – also known as “I&I”. Inflow is the rainwater that enters the system directly from point sources, such as missing manhole lids, building sump pumps, or downspouts connected to the sanitary sewer collection system. Infiltration occurs when groundwater enters through leaking joints, cracked pipes, or deteriorated manholes in the collection system.

Project No. 014-2994 9 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

Most all sanitary sewer systems experience I&I to some degree, and management programs should be adopted and routinely implemented to mitigate the costs associated with conveying and treating high wet-weather flows. Major cost concerns include additional wear on pumps and other mechanics, cost of operation of pumps and treatment plant equipment/chemicals, overflow cleanup, and the necessary system upgrades to handle large flow rates. While the 2001 Wastewater Facility Plan by Sprenkle & Associates noted that collection system defects existed and I&I was high, this plan focused on increasing treatment capacity and capability rather than on reducing I&I in the collection system.

Through their recent sewer line cleaning and televising efforts, Cassville Public Works staff have found numerous defects throughout the collection system, almost entirely in the older areas of the system that have clay sewer lines. Unfortunately, these areas also tend to be in the lower elevations of the service area and along Flat Creek, and are thus subject to highly saturated ground conditions.

b. Smoke Testing In 2005, the City of Cassville contracted Wade & Associates, Inc. (acquired by CH2M Hill in 2007) to conduct smoke testing on the sanitary sewer system. This testing involves using fans located on adjacent manholes to push smoke into the lines; where the smoke can find a leak in the system, a plume will arise, which can be marked for later repair. These defects are broken into two sectors based on ownership – public and private. Public defects include issues with sewer mains and manholes, while private defects include sources located from the service connection up to and inside the home.

In total, Wade & Associates was able to test 518 line segments for a total of approximately 135,000 linear feet. Work crews were able to located 191 defects in the sanitary sewers, primarily in the private sector, which accounted for 166 of these defects. Furthermore, the largest single cause of defect was found to be service laterals, with 106 occurrences. Unfortunately, due to a lack of funding, the City has been unable to take action in resolving the private sector issues, other than replacing a few cleanout caps around town.

c. 2011 Flow Monitoring In 2011, Olsson Associates performed a wastewater system study to develop a Bypass Elimination Plan (BEP) for Cassville. This plan established action steps for the City in accordance with a signed Voluntary Compliance Agreement (VCA) with MoDNR. The VCA was necessary as previous permit requirements that allowed for discharges from the lagoon (Outfall #002) were eliminated, since bypassing secondary (biological) treatment was no longer allowed. Included in the BEP was flow monitoring, collection system capacity analysis, WWTP capacity analysis, and recommendations to address I&I.

Project No. 014-2994 10 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

Flow monitoring for the BEP consisted of temporary installation of six (6) flow meters from April to July of 2011. The meters were placed in manholes above the flow, using Doppler radar to measure surface velocity and ultrasonic pulse echo to measure depth, from which the instantaneous flow rate was able to be calculated every fifteen (15) minutes. Over the course of the study numerous rain events and dry periods allowed for a sampling of the systems response to various conditions allowing for both base line and heavy use models. Most notably was that the treatment plant received a peak inflow rate of 4.24 million gallons per day (MGD) and twenty (20) consecutive days with inflow greater than the WWTP design maximum of 1.1 MGD. Frequent discharge from the Outfall #002 was required to prevent the lagoon from spilling over.

During the flow monitoring period, several incidents of sanitary sewer overflows (SSOs) occurred throughout the system. SSOs result from collection system flow exceeding the pipe capacity, resulting in discharges from available relief points, which include but are not limited to manholes, cleanouts, cracked pipes, and loose joints.

Also presented in the BEP report were several alternatives to provide additional capacity and rehabilitation to the collection system to help mitigate the need for discharging from Outfall #002. The BEP was finalized and submitted to MoDNR in 2012. However, the drought conditions experienced throughout 2012 showed that an increase in collection system piping size to the WWTP was not necessary; but rather a concentrated effort on reducing wet-weather I&I flows through rehabilitation of the collection system was needed.

d. Manhole Inspections In 2014, the City of Cassville began a standardized method of evaluating manholes in the collection system by means of structure location, composition, and condition. The inspections included sixty-nine (69) manholes from across the service area and revealed the structures to be in generally good condition. Seventeen (17) defects were identified from the evaluations, the majority resulting from deteriorated brick or block structural materials. Joints are the most common source of infiltration and older masonry manholes have vastly higher total joint lengths between structural members than precast concrete. Additional defects included a defective lid, signs of surcharge, and manhole steps in poor condition. Copies of the inspection reports are on-file with the City.

e. 2015 Flow Monitoring In 2015, WWTP influent flow monitoring was conducted between May 8th and July 23rd by placing a single flow meter (ISCO LaserFlow) in the manhole just upstream of the WWTP influent pump station. This monitoring period coincided with an uncommonly wet summer in which multiple heavy rainfall events occurred. A summary of the data collected can be found in Table V-6 with associated analysis discussed in Section V.

Project No. 014-2994 11 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

B. Existing Wastewater Treatment Plant (WWTP) Cassville operates a single WWTP approximately half a mile northeast of city proper on Farm Road 1120 (also known as Partridge Dr.). The current WWTP operator is Steve Henderson, certified Level A (#2842). The plant was upgraded in 2003 to a permitted design flow of 1.1 MGD. Influent enters the WWTP through a twenty-four inch (24”) PVC pipe where flows are screened for debris. Flows enter the WWTP through an influent pump station, providing the necessary initial head to allow flows to gravity flow through the plant. When flows are projected to top 1.2 MGD, a weir located along the influent channel that receives the pumped influent flow can be adjusted to divert incoming flows greater than 1.2 MGD to the lagoon and prevent flooding within the mechanical plant. The excess flow (>1.2 MGD) is diverted to an 18-acre storage basin that once served as the main treatment lagoon for the service area before the mechanical treatment plant was constructed. During wet-weather periods that result in sustained incoming flow diversion to the lagoon that consumes the available storage capacity, a valve can be opened to discharge from the lagoon at Outfall #002, directly to Flat Creek, to avoid overtopping the lagoon berms. Since there is no flow meter on the lagoon influent or effluent structures, no direct means of measuring the volume diverted or discharged is available.

The mechanical plant currently includes the following components: • 24” PVC influent line from plant entrance to headworks • Screening • 4.8 MGD influent pump station • Flow control structure (diversion weir) and influent flow meter (to mechanical plant) • Cyclone grit removal • Anaerobic selector basin to facilitate biological phosphorus removal • 1,000,000-gallon aeration basin • Liquid alum feed system • 4 – 24’ diameter clarifiers (2.17 MGD capacity at 1,200 gpd/sf) • 2 – Kruger disc filters (rated for 2.17 MGD each) • UV disinfection – 2.17 MGD design flow • Parshall flume/ultrasonic effluent flow meter • 400,000-gallon aerated sludge digester

The 2010 discharge requirement revisions by MoDNR necessitate that all wastewater treatment facilities treat sewage with secondary, biological processes before discharging to receiving streams. Without a means of measuring discharge volumes from Outfall #002, it is not possible to accurately calculate the additional treatment capacity needed at the WWTP to handle anticipated wet-weather flows. From the information proved by plant staff, a maximum discharge volume from Outfall #002 is noted as 594,000 gallons per day for occasions in which the lagoon is discharging all day. The typical procedure is for the diversion weir from the plant to the lagoon to be set ahead of time, in anticipation of rain, so the plant does not take on more than a 1.2 MGD flow through the mechanical processes.

V. HYDRAULIC CAPACITY EVALUATION

A. Water Use and Wastewater Treatment Facility Flow Monitoring To better determine the effects that I&I is having on the system, water usage from the city’s groundwater wells was compared to wastewater flow measurements to quantify the volume of water entering the sewer system that is over and above the volume expected due to normal customer use. Three sources of information were analyzed to determine the level of I&I reduction necessary to mitigate the need for discharges from Outfall #002 – 1) historical information regarding daily drinking water and wastewater volumes, 2) WWTP influent flow rates during the recent 2015 flow monitoring, and 3) WWTP flow monitoring rates measured in 2011. From a comparison of flow rates from historical dry-weather periods, customer water usage, and recent influent monitoring, it is possible to establish an estimated I&I volume for the wastewater system during wet-weather events and devise a level of necessary mitigation.

First, information was analyzed for five full calendar years of 2010 to 2014 regarding the water volume pumped from the City-operated drinking water wells, the water volume billed to customers, and the wastewater volume discharged from the WWTP. For comparison, the water pumped from the wells was used as the basis for water placed into the sanitary sewers as metered water billings do not always reflect accurate usage. Tabulated information regarding well water pumped and water billing can be found below in Table V-1.

Due to the large discrepancy between well water pumped and water sold to customers, an average of the two was taken as a probable volume placed into the sewers. This was assumed as the cause of the variance could not be readily determined and a review of the water system is quite extensive, which is not within the scope of this wastewater plan. The average of the two water categories above calculates out to be roughly 116 GPD per person.

For comparison with the average water usage for the service area, the average WWTP effluent volume was calculated to determine daily system wastewater flows. Effluent data is collected daily from the WWTP as the treated water passes through a Parshall flume monitored by an ultrasonic meter. Additionally, precipitation levels measured from a rain gauge located at the WWTP were also analyzed. A summary of the recorded information for 2010 through 2014 is provided below in Table V-2.

As shown in Table V-2, over the recent 60-month period, the average effluent flow from the mechanical WWTP is approximately 0.66 MGD, and a peak single day treated flow of 1.6 MGD was recorded. However, peak WWTP flow values are limited by the fact there is no means of measuring volumes diverted to the lagoon. A maximum value of 594,000 gallons is listed as volume discharged from Outfall #002 into Flat Creek.

Precipitation values are included in Table V-2 to correlate rainfall with increases in sanitary sewer flows. Most notably are periods of heavy precipitation such as April and May of 2011. A total rainfall of over twenty inches (20”) of rain fell during that two-month period, nearly half of the average yearly precipitation for the area, during which the WWTP saw large increases in flow volumes. It should be noted that precipitation events may have occurred at the beginning or ending of a month, so though a high rainfall level was recorded for a particular time period, the effects may have been experienced during the following month. Thus, adjacent months should be considered when evaluating the effect I&I has on the system.

Dry periods also give perspective on the effect rainfall has on treatment plant flows as the plant saw its lowest ratio of wastewater-to-water in January of 2011, when that month and the previous month totaled only slightly over one inch of precipitation. During this time, but not exclusively for this period only, the system actually registered lower volumes at the plant than water pumped from the wells. This was evidenced throughout much of 2012 when the area experienced a significant prolonged drought. It also indicates the wastewater collection system is likely losing flow to the surrounding soil through defects in the system.

Though the recorded WWTP effluent data (Outfall #001) do not fully portray the effects of wet- weather events due to the lack of diverted flow and Outfall #002 data, it is possible to utilize the flows during prolonged dry periods to establish a baseline for dry-weather system flows. Accordingly, data was evaluated for the five months with the lowest average monthly effluent and is summarized below in Table V-3. The result is that recent dry-weather sewer flows can be approximated as 440,000 GPD.

From the dry-weather flow volumes shown in Table V-3, the average flow of wastewater discharged by the WWTP per person during dry periods can be calculated based on the population estimates shown in Table V-1. These calculations are summarized in Table V-4, and result in an average daily dry-weather wastewater flow of 132 GPD/person.

Drinking water usage between 2010 and 2014 was also considered. From the collected data, the Percent Wastewater (discharged by Outfall #001 and #002) versus Water Usage (pumped by the wells) was calculated to represent the volume of wastewater being discharged every month compared to the amount of well water pumped into the drinking water system. Results of the wastewater-to-water comparison are presented in Table V-5. The total monthly rainfall received at the WWTP is also included in the table for perspective on wet-weather conditions.

Though the data in Table V-5 provide a good correlation between precipitation events and increases or decreases in wastewater handled by the treatment system, it is not possible to determine the true volumes of water being conveyed to the WWTP due to the unrecorded flow diversion to the lagoon. To better determine influent wastewater flow rates, and in preparation for this Master Plan as well as the 2012 BEP, the City installed a temporary flow meter in the influent line to the WWTP. Between May 9th and July 23rd of 2015, real time readings were logged by an ISCO LaserFlow meter for velocity, depth, and flow rate, every fifteen (15) minutes. This information, in accompaniment with Outfall #001 data, allows for an estimation of the wastewater volumes entering the lagoon.

For comparison with recent WWTP incoming flow, the data summarized in Table V-6 includes the tabulated daily influent flow volumes calculated from 15-minute readings, along with daily precipitation values, well water pumped, the calculated (estimated) lagoon influent flow, and the recorded lagoon effluent flow for each day during the 2015 influent flow monitoring period.

Rain events, like that which occurred on July 7th, demonstrate the delayed process in which the groundwater table affects the sanitary system. Though the highest rainfall occurred on July 7th, the highest volume discharged by the WWTP was on July 8th, the highest volume measured in the influent line was on July 9th, and Outfall #002 discharged for eight days after the rain stopped on July 10th. The average influent recorded was slightly over 1.8 MGD, well above the WWTP design capacity.

The blue highlighted cells of recorded WWTP Influent represent the thirty (30) consecutive days of highest flows from which to determine an average wet-weather influent flow rate of 2.13 MGD, which is nearly double the WWTP’s design capacity. During this 30-day wet period between June 18th and July 17th, on only one day (July 6th) did the plant influent meter record a lower volume than the design WWTP capacity of 1.1 MGD.

A graphical comparison of the tabular information presented in the above table is shown in Figure V-1 below, which shows how vastly different the well water pumped, WWTP influent, and

Project No. 014-2994 22 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

WWTP/lagoon effluent flows can be during wet-weather periods. The prolonged stretches of high influent flow after the rain has stopped are indicative of a severe infiltration problem rather than an inflow problem. The initial rehabilitation efforts, therefore, should concentrate on remedies to curb infiltration in the sewer mains.

FIGURE V-1: CASSVILLE WELL WATER PUMPED, WWTP FLOWS, AND RAINFALL.

During the 2015 influent flow monitoring, a maximum total day flow of 3.6 million gallons was recorded on June 19th. Instantaneous flows to the plant exceeded 4 MGD for short durations. The rain event that lead to the maximum flow during the monitoring period actually took place from June 12th to the 18th, over which time 7.5” of rain were recorded. With the data showing that even after the rain stopped on June 18th, influent levels continued to remain near or above 2.0 MGD until the next rain event on June 26th is an indication of just how much flow is related to infiltration rather than inflow. Had inflow been more of a factor, peak WWTP influent flows would occur very soon after the rainfall starts and then dissipate quickly once the precipitation event ends. A rain event of similar size to the June 2015 event was also experienced during the flow monitoring period in 2011, in preparation for the BEP report. For the 2011 rain event, a maximum day flow of 3.45 MGD was experienced. Comparisons of wet-weather flow volumes to population are summarized in Table V-7.

Table V-7 demonstrates the wide fluctuation in flows experienced at the WWTP during dry and wet periods and provides data that is useful in determining an I&I reduction level for Cassville to work toward. The maximum day flow rates during the two monitoring periods (2011 and 2015) are also included in Table V-7 to show the recent consistency in max-day influent flows, but the dry- and wet-month flow rates listed establish the current extremes the WWTP can expect to experience in upcoming years. It is worth mentioning that the unsurcharged, full-flow capacity of the 24-inch sewer interceptor line leading to the WWTP is approximately 5 MGD, assuming minimum slope conditions.

The estimated range of WWTP influent flow rates for the projected service area populations was based on both dry-weather and wet-weather conditions. Table V-8 shows projected influent flows based on the per capita Historical WWTP Effluent Dry-Month Flow (132 GPD/person) and the per capita WWTP Influent Monitoring Wet-Month Flow (608 GPD/person) shown in Table V- 7 throughout the 10-year planning period. While the projected dry-weather flows are easily within the 1.2 MGD hydraulic capacity of the WWTP, the wet-weather flows need immediate mitigation in order to avoid filling up the lagoon and ultimately discharging from Outfall #002.

B. Wet Weather Flow Projections versus Hydraulic Capacity With an understanding of the current wet-weather flows experienced by Cassville’s collection system, the needed level of extraneous flow reduction can be quantified in order to eliminate discharges from Outfall #002 without having to increase WWTP capacity. Table V-9 tabulates the available treatment capacity flow per capita based on the existing WWTP hydraulic capacity (1.2 MGD) and the projected populations, and compares this capacity with the current per capita wet-weather flow to determine the level of flow reduction needed to stay within the capacity of the existing WWTP. As expected, as the population increases during the planning period, there is less capacity per capita available in the existing WWTP, and as an average, Cassville should strive to achieve a 50% reduction in wet-weather flows to allow future flows to stay within the treatment plant’s hydraulic capacity.

In consideration of the conclusions drawn from the recent and historical data analyzed, which include Cassville’s wet-weather conditions stem more from the effects of infiltration rather than direct inflow, and that a 50% reduction in wet-weather flows is needed, specific wastewater system evaluations and recommendations can be developed. The following section summarizes recent collection system investigations performed and the resulting system defects identified.

VI. RECENT CCTV EFFORTS AND IDENTIFIED PROBLEM AREAS

A. General The City of Cassville owns a sewer line jetter and a closed-circuit television (CCTV) camera and has dedicated two (2) full time employees to perform sewer line cleaning and operate the camera to inspect the sewer lines. As part of the investigative efforts associated with this Collection System Facility Plan, the City has recently inspected almost all clay sewer mains within the collection system, which are primarily located around the older sections of the City and in the vicinity of Flat Creek. DVDs of the inspections were presented to Olsson Associates for evaluation of lines, determination of defects, and prioritization of repairs. An evaluation of each DVD was logged in a spreadsheet with noted defects, start and finish manhole, pipe size and material, flow direction, grease and debris settling, and length of sewer line. The full spreadsheet can be found in Appendix A.

B. Observed Collection System Defects The following is a listing and description of the defects noted during the evaluation of the Cassville sanitary sewer collection system CCTV videos:

1. Cracked Joint – Perhaps the most common defect noted in the system, this is a crack originating from the joint between two pipes. The crack could be listed as minor, otherwise known as “hairline”, to major, which would indicate a large open crack with a visible gap. The crack can run radially around the pipe or parallel along the pipe.

2. Cracked Pipe – Though these cracks can also originate from the joint of the pipe, the distinction was made that the primary damage has occurred further along the pipe section. This was also applied to cracks that acted along multiple pipe sections as though the joint were not an obstacle and the damage continues from one pipe to the next.

3. Broken Pipe – Cracks in pipes can continue until sections of pipe become separated, allowing for the section to break away or fall out of place. This defect is noted if the cracked pipe has resulted in a hole. Minor broken pipes may be noted if the bell section of a pipe end has broken away, revealing easy access for groundwater. Severely broken pipes may include several square inches of missing pipe, with the surrounding material exposed.

4. Roots in Pipe/Lateral/Joint/Crack – This is also a common defect found in Cassville’s system. This defect refers to tree roots that have penetrated the system through an opening or joint in the system. Minor roots may be as small as blades of grass, indicating a small gap in a joint or separation along a crack; or major as some root curtains and root balls restrict flow by blocking a significant percentage of the pipe area, which can lead to line backups, SSOs, and debris settling, as well as prevent inspection completion.

5. Offset Joint – Joint separation and offsetting is common in older clay systems as joint seals fail and both piping and manholes settle. Gaps in joints allow flow to pass in and out of the pipe which can washout or erode surrounding material. The remaining void allows the pipe

Project No. 014-2994 27 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

to further settle, increasing the size of the gap or creating minor to moderate flow backups. Typical minor joint offsets are most easily noted when the CCTV camera jumps over joints. Major offsets allow visual inspection of the surrounding pipe material.

6. Inflow and Infiltration – Inflow is not typically noted as it would require televising during a rain event, which would impede inspection of the line due to high flow levels. Infiltration is more readily visible as raised groundwater levels may take many days to drop after a heavy rainfall event, allowing for greater opportunity to discover. Minor infiltration may be clear water dripping from a pipe joint and measured in fractions of a gallon per hour, or major infiltration appearing as a running faucet from a crack measured in gallons per minute. Varying degrees of infiltration were noted coming from several service lateral connections, cracks, joints, and manholes.

7. Settled Solids – Settled solids typically take the form of silty-sand material as well as other organic material that has fallen to the bottom of the pipe to restrict flow. These occur when pipe flows do not reach a scouring velocity, typically considered a minimum of two feet-per- second (2 fps). Minor settled solids were noted if the flow was low enough to visibly see the solids not clearing from the bottom of the pipe. Major settled solids occurred as a result of severely restricted flow from a blockage or pipe sag.

8. Debris – This includes a vast array of material located in the pipe that may restrict flow or even create an ever-increasing dam. A rock, small piece of pipe, or stuck bathroom tissue would be noted as minor. In a pipe not able to reach the necessary scour velocity, a small rock may accumulate floating bathroom tissue, baby wipes, hygiene products, trash, or other material, causing flow backups that can be several feet long. Large debris can also cause issues even if cleared from the collection system as the materials listed above can shorten pump impeller life and, occasionally, block impellers from spinning. Multiple municipalities have filed complaints with companies that produce “Flushable Wipes” and some have gone so far as to file legal action as this label is wrong. The flushable wipes do not break down as readily as bathroom tissue and rapidly accumulate at any snag point.

9. Broken Invert – Some manholes in the inspections were noted to have broken inverts, or a half-pipe section at the bottom of the manhole. A minor break would have been noted if the invert was cracked, while a major break was noted if a section of the concrete invert or clay pipe material along the invert was missing.

10. Grease – Typically, grease is flushed away with the flow as emulsifiers, such as soap and laundry detergent, keep the grease suspended until treatment. However, users that flush high volumes of grease – be it a restaurant with no or a poorly-functioning grease trap or a resident that improperly disposes of it after cooking – can cause grease deposits that can restrict flow in service laterals to the point of complete blockage and/or create buildup in system lines that restrict flow and result in settled solids upstream. The City does utilize a degreaser when needed and has a monthly grease trap program.

City of Cassville, Missouri Wastewater Collection System Facility Plan

Review of the City’s sanitary sewer video logs provided insight into the condition of the system and the steps to be performed to alleviate the issues. In general, many of the clay pipes located throughout the older areas of the City exhibited cracks, root intrusion, grease and debris buildup, as well as joint offsets. Where appropriate, the defects were described as slight, minor, moderate, major, heavy, etc. to indicate the severity of the issue. Though visual I&I was not documented frequently, the potential for I&I is still evident, as video inspections benefit from dry- weather conditions in order to reduce the volume of water in the system, thus providing better visibility of the pipes. Pipes with flow depths over forty percent (40%) are considered too full to perform a proper visual evaluation.

VII. PROJECT ALTERNATIVE ANALYSIS

A. Repair Alternatives In addition to the wording used to describe the severity of the defects observed through review of the CCTV video, each sewer line segment was assigned a “Priority” number from one through five (1 – 5), with five (5) being the highest priority for correction. Many minor defects do not require restoration at this time, but were noted for monitoring in future evaluations. Ten potential sewer rehabilitation techniques were considered for appropriate application, implementation, and cost in order to recommend the best-value alternative for the line segment deficiencies observed. A listing of the rehabilitation techniques is as follows:

1. Open-Cut Replacement – This involves the replacement of the entire sewer line segment by means of excavation. This is typically the most costly alternative as the method is very invasive, oftentimes requires bypass pumping, and can require restoration of other infrastructure such as streets, sidewalks, curb and gutter, utility poles, and driveways.

2. Open-Cut Point Repair – This method is applied to a small section of pipe in need of replacement. Commonly, this involves excavating and repairing a small section of collapsed line or severely offset joints in areas where there will be minimal above-ground disturbance.

3. Cut Protruding Tap – Occasionally a service connection will have protruded into the main pipeline which causes an obstacle for the CCTV camera and restricts the flow. Correction requires use of a rotating circular cutting tool at the end of a jetting hose to saw through the tap, leaving the lateral connection more flush with the main pipeline wall.

4. Cured-In-Place Pipe (CIPP) – This trenchless method of rehabilitation requires the use of large, specialized equipment and material that is traditionally not cost effective for direct purchase by a city, but rather lends itself to contracting with a specialized company for installation. The process begins by cleaning the line segment before an equipment truck parks on each manhole at either end. One truck contains a “liner” of inside-out pipe fabric that is impregnated with a hardening resin. The liner is inflated into the line, inverting into the proper orientation as it travels through the line. Once the liner is in place, the crew begins curing the resin by attaching a steam blower to one end. The steam heats the resin, causing the new liner to harden. The service connections associated with the host pipe are then re-instated with a robotic saw that cuts a hole in the cured liner at the exact location of each service connection. Since CIPP liners do not adhere tightly to the host pipe walls, groundwater that enters the host pipe can still track along the outside of the liner and will eventually enter the liner through the hole associated with the re-instated service connections. To avoid this, it is oftentimes prudent to also install a cured-in-place lateral connection repair (LCR) at each service connection after the CIPP process is complete.

5. Cured-In-Place Lateral Connection Repair (LCR) – Similar in concept to the CIPP liner, but using different trenchless installation equipment and a 100%-solids hardening resin, this rehabilitation technique installs a short T-shaped liner in the main line at the location of the

Project No. 014-2994 30 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

service connection and inverts a portion of the liner about 12”-18” up into the service lateral. The resin binds the LCR liner to the CIPP liner and the adjacent service connection piping well enough to resist significant infiltration into the service connection point as a result of water tracking along the host pipe. Similarly, a bad service line connection (cracked, offset joint, etc.) with a structurally-sound sewer main can also permit groundwater and root intrusion, and would only require a short LCR liner to remedy, regardless of whether the sewer main was CIPP-lined. Trenchless sewer rehabilitation companies can also install longer lengths of lateral liners if damage to the service lateral is extensive.

6. Cured-in-Place Pipe End Seal – Cured-in-place pipe end seals are used to trenchlessly repair the sewer main’s connection to a manhole. These are installed at the main-to- manhole interface, extend a couple feet into the sewer main, and utilize a 100%-solids bonding resin just like the LCRs.

7. Cured-In-Place Point Liner (CIP Point Liner) – This method of trenchless, cured-in-place liner utilizes equipment already owned by the City of Cassville, thus drastically reducing costs compared to contracting out. A CIP Point Liner is a short section, typically 4’-6’ long, that utilizes a 100%-solids resin to adhere to the walls of the host pipe to repair short- spanning defects. CIP point liners can be used in series to rehabilitate longer cracks or breaks, averting the cost of a full manhole-to-manhole CIPP liner.

8. Manhole Relining – Relining a manhole can be achieved by different methods, but the most cost effective means at this time is by grouting. With grouting, a crewman will enter the manhole and trowel a waterproof grout onto the entire interior surface of the manhole; from the invert to the lid. Proper installation has effectively eliminated manhole leaks without the need for specialized equipment for liners or epoxies, or for full manhole replacement.

9. Joint Inspection and Grouting – This trenchless sewer rehabilitation method is an alternative to CIPP-lining and is also being used in several cities throughout Missouri. To implement this technique, the sewer lines are first cleaned to provide a smooth surface for pressure testing. The key piece of equipment used for this method is a pressure-testing and grout- filling cylinder that just fits inside the sewer line. On both ends of the cylinder is a rubber plug that inflates to seal the joint section being tested. If the joint fails a pressure test, grout can be injected through the cylinder, into the joint, and out into the substrate to fill any void space just outside the pipe to seal the leak. The grout sets quickly to allow the equipment to proceed to the next section for testing and repair.

10. Lateral Connection Grout Repair – As with sewer main joint testing and grouting, lateral connection grout repair uses specialized equipment to first pressure test and then grout- repair, as needed, lateral connections to the sewer main. This technique allows for the filling of broken connections, cracked lateral pipes (to the extent of the equipment), and failed gasket seals. The equipment is slightly different from the sewer main joint cylinder in that a testing and grouting liner is first inflated into the service lateral to create a pressure- testing seal and provide a mold for grouting, if necessary.

B. Gravity Main Lines The City of Cassville CCTV-videoed nearly 300 VCP gravity lines, from which 264 defects were identified. Such a high percentage of defects to inspections reveals the need for significant rehabilitation and a prioritized plan of action to implement the repairs. As each line of CCTV video was reviewed, consideration was placed on the importance of addressing the deficiencies observed and a priority number from one to five (1-5) was given; with five (5) being the most severe. The highest-priority lines exhibited a need for near-term attention as the defect is currently preventing proper system operation. A common example would be roots or debris blocking over half of the cross-sectional area of a sewer line, causing backups during normal flow conditions. Generally, most of the high-priority issues can be temporarily addressed with heavy-duty line cleaning, and then follow-up with CCTV inspection to determine which rehabilitation method to implement thereafter.

Following the high-priority cleaning and re-inspection, a plan to systematically rehabilitate the next priority gravity lines can be implemented. Development of the rehabilitation plan recommended in this report first involved the determination of which areas are most likely to experience I&I in the system, with an emphasis on the areas most subject to infiltration. Though a crack may be larger in one pipe than another, location of the pipe should be taken into account when determining repair benefits.

Accordingly, it appears the City can achieve its greatest value for wet-weather flow reduction by concentrating initial rehabilitation efforts on the low-lying areas of the collection system that lie along the floodplain associated with Flat Creek and its tributaries. To this end, a “Saturation Zone” was identified within the service area, where the highest levels of infiltration are likely to occur. Topographic contour lines, floodplain maps, and the location of gravity sewer lines were used to delineate the Saturation Zone, in which to concentrate the next-highest priority of rehabilitation efforts. Within the Saturation Zone, sewer lines are likely to remain in contact with the shallow groundwater table for days or weeks after a rain event, allowing persistent infiltration through defects in the piping and associated manholes. A map of the Saturation Zone can be found in Exhibit 3.

The Saturation Zone primarily includes areas within and along the Flat Creek floodplain, consisting of a total gravity-line length of nearly 100,000 feet. A summary of the system within the Saturation Zone and the remaining Outer Zone can be found in Table VII-1. All of the lines associated with the area serviced by the Sherwood Forest Pump Station are in the Outer Zone.

After developing the CCTV review records, specific rehabilitation efforts were itemized within the Saturation Zone and the Outer Zone. However, with the wide-array of defects identified through review of the CCTV videos, as well as an understanding of the impact infiltration has on the observed wet-weather flows in Cassville, a repair strategy of joint and service connection pressure-testing and grouting is recommended to address the broadest range of issues expected in the Saturation Zone. Implementing a plan to test the gravity lines within the Saturation Zone will also provide additional inspection details regarding defect repairs which are not applicable to grouting. As the joint testing is conducted, more severe defects can be noted while completing the line inspections that were initially hindered due to blockages. Though some defects will require various degrees of additional attention, a broad-stroke action of joint- testing and grouting is expected to address the majority of gravity line defects in the Saturation Zone, and provide the greatest value for the City’s rehabilitation investment.

C. Service Line Connections Three primary methods of addressing defective service line connections have been noted in the CCTV inspection report: 1) cured-in-place lateral connection repair (LCR), 2) pressure-testing and grouting, and 3) open-cut repair. Additionally, some connections appear to have been abandoned and can be removed as sources of I&I by installing a CIP point liner. As gravity line joint pressure-testing and grouting is implemented, the City should concurrently pressure-test and grout service connections.

Beyond the service connection, correcting defective service lines have been an issue for municipalities for decades as I&I sources are rarely addressed beyond the connection point, which typically extends onto private property. Some attempts have been made previously with smoke testing and building inspections to locate defects, but property owners are generally not inclined to participate in rehabilitation programs.

City of Cassville, Missouri Wastewater Collection System Facility Plan

More recently, MoDNR and municipalities have been teaming up to provide funding for repairs through grants that offset customer rate increases. With this method, the State, City, and customers shoulder a share of the financial responsibility to perform repairs on a completely voluntary basis. Every property owner is given multiple opportunities for an inspection team to locate any possible source of I&I beyond the connection to the sewer main. Sources of I&I are addressed through a third party plumber that has agreed upon a fee schedule of each issue. The property owner is not contractually obligated at any time to continue with the program and any grievances are alleviated as soon as possible. No direct cost is associated to the property owner, though they receive services they may not have been financially capable of providing themselves. The City sees the reduction in system loading during wet-weather conditions along with a reduction in treatment costs as volumes decrease. The City also benefits from reduced sanitary sewer overflows and an increase in the useful life duration of the existing WWTP capacity.

D. Manholes Also located within the Saturation Zone are approximately 300 manholes. Though manhole condition was difficult to determine based on the low light provided by the CCTV sewer line camera, several manholes were noted to have defects, including but not limited to: infiltration, broken inverts, and visible sunlight through structure. An inventory of the system manholes within the Saturation Zone and Outer Zone is provided by individual basin below in Table VII-2.

The City has already begun a manhole inspection program, with a total of sixty-nine inspected thus far. Continuing this program with a focus on the Saturation Zone will provide a means of prioritizing manhole rehabilitation so immediate needs can be addressed in the short-term. A modest schedule of manhole rehabilitation of thirty-five (35) manholes per year for the next ten years is recommended to address issues associated with I&I at the manholes.

VIII. RECOMMENDED PROJECT ALTERNATIVE SUMMARY AND JUSTIFICATION

A. Recommended Rehabilitation Alternatives (Years 1-5) Based on the observed deficiencies, pipe material, and topographic features, division of the collection system into the areas within and outside of a delineated “Saturation Zone” is recommended to guide the systematic rehabilitation of Cassville’s collection system. Approximate gravity sewer line lengths were compiled in Table VII-2 for both inside and outside the Saturation Zone. City staff have stated that two 5-year plans are desired to accomplish the recommended sewer rehabilitation on both the public and private portions of the sewer system. The following plans of action summarize the recommended rehabilitation efforts for years 1-5 and years 6-10.

1. Within the Saturation Zone The oldest parts of the City are located within close proximity to Flat Creek and its many tributaries, as access to water was paramount before the founding of Cassville. This has resulted in the aging system suffering the greatest negative effects in sewer collection lines located within flood plains, areas with shallow groundwater levels, and soil with high water retention times. The Saturation Zone was established to provide a basis for initial repairs that will achieve the greatest results toward reducing wet-weather infiltration.

Some of the gravity lines within the Saturation Zone are recommended to have specific repairs made, as determined through CCTV review; such repairs include both open-cut and trenchless point repairs as well as CIPP-lining of entire lines where the frequency and severity of defects necessitates full-pipe rehabilitation. For the remainder of the pipe located within the Saturation Zone, a systematic approach of pressure-testing and grout-filling of pipeline joints and service connections is recommended. This proposed rehabilitation will address the majority of issues discovered in the CCTV inspections as well as locate joint defects not previously detectable.

In addition, a systematic manhole rehabilitation program will provide further I&I reduction as many of the CCTV-reviewed manholes are constructed of concrete or brick masonry with deteriorated grout joints. Relining the manhole involves covering the entire interior surface with grout or epoxy to alleviate I&I. This rehabilitation effort is proposed for the entire system in order to address manhole deficiencies both inside and outside the Saturation Zone.

2. Outside Saturation Zone As stated above, a system-wide manhole rehabilitation program to address deficient structures is recommended. It is likely the majority of manholes are located within the Saturation Zone due to the age of the system in that area, but structures throughout the collection system should be investigated for deficiencies that are allowing I&I.

Project No. 014-2994 35 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

Due to the presence of VCP sewer lines outside of the Saturation Zone, some of the gravity lines reviewed for the project in the Outer Zone have also been recommended for repairs such as CIPP-lining, CIP point repairs, and LCRs, as well as open-cut repairs and additional cleaning and televising. Though these recommended sites of rehabilitation are located outside of the Saturation Zone, they have a high priority for corrective action.

B. Private Inflow and Infiltration Abatement (Years 6-10) Implementation of a program to inspect and evaluate the private connections to the wastewater collection system beyond the typical reach of the municipality can be beneficial to the homeowner, the City, and the state. A combined effort by all parties has been successfully implemented in other municipalities where previous efforts that put the burden of corrective action solely upon the private landowner have failed. Once a properly-funded program for private I&I abatement is established – and an emphasis by the City that the issues to be corrected are a community problem, not just a private owner problem – home and business owners are likely to be much more willing to cooperate for the common benefit.

The recommended method for implementing a private I&I abatement program begins with an estimated budget based on an expected number of repairs and an average cost per repair. Estimates for the number of repairs can be based on a number of factors – including the size of the area to be rehabilitated, the number of connections within the rehabilitation area, any previous inspection data, the required level of reduction, and the level of repair desired. Perhaps the most important, but least considered, is the level of repair desired. For this, the cost of the individual repair can vary greatly – for example, repairing a broken cleanout lid can included replacing the cover for less than $25 or be as involved as riser replacement and a vault enclosure costing over $250. The new cleanout lid will remove the opening as a source of I&I, but the vault enclosure will prevent the cleanout from being broken again.

The involvement of professional plumbers throughout the implementation process will aid in establishing a cost for repairs. Providing an opportunity for multiple plumbing companies to discuss a fixed rate structure for the project will help in establishing a project budget as well as a list of contractors for when the City is ready to institute repairs. The City directly contracting the repairs with a fixed price schedule has the benefits of ensuring specific criteria are met by the plumber such as experience, licensing, and bonding; work is performed to the standards established at the onset of the program; work is distributed fairly; and final payment is not made until completion of the repairs.

Buildings within the selected private rehabilitation area should be inspected by no less than two individuals trained to inspect plumbing fixtures and determine compliance. Assuring owners of the voluntary nature of the program and emphasizing the specific target of the evaluation has shown to result in greatly higher inspection rates and fewer conflicts with distrusting individuals. Additionally, every effort to inform the citizens in the area through newspaper notifications, public information meetings, radio and television outlets, and mailed or door-hung fliers provides reassurance of the legitimacy of the program. Periodic statistical updates regarding number of inspections and repairs will further assist with public awareness.

Project No. 014-2994 36 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

Once an inspection is performed and a deficiency is detected, the property owner should be given the opportunity to choose from the list of pre-selected plumbers prior to the City choosing. The plumber would be compensated the pre-agreed cost of the repair upon completion and final inspection by the city’s inspectors.

Planning for private I&I abatement should involve consideration of the successes and failures of other programs as well as an introspective look at the municipality’s own capabilities and limitations. For this Facility Plan, the cost of a private I&I abatement program was estimated from recent data collected for the City of Springfield, Missouri private I&I abatement program. In general, about one-third of the establishments inspected required some form of corrective action. In consideration of the labor cost for inspections and follow-up evaluations after repairs, in addition to the cost of the repairs themselves, the average cost of the program can be estimated at about $3,000 per establishment in which a deficiency was identified. This average amount also covers the cost of inspecting facilities in which a defect is not identified.

For Cassville, with about 1,500 sewer connections, a preliminary budget of $1,500,000 should be considered for a private I&I abatement program based on one-third of the sewer connections needing a $3,000 average investment. It may be advantageous for the City to take an approach similar to the public-side sewer system rehabilitation and concentrate initially on establishments in the Saturation Zone, where approximately half of the sewer connections are affected. However, since this area is the oldest part of town, the percentage of facilities with defects may be higher than 33%.

C. Cost Opinion for Proposed Rehabilitation An opinion of probable construction cost has been developed for the recommended collection system rehabilitation items for Cassville. No capital improvements involving the WWTP are being recommended in this report. The most significant and highest-priority improvements recommended involve pressure-testing and grouting sewer main joints and service connections within the Saturation Zone and addressing the critical issues noted during review of the recent CCTV videos. Following this initial effort and subsequent wet-weather flow analysis to determine the I&I reduction achieved through the improvements, a private I&I abatement program should be implemented.

Table VIII-1 presents an opinion of probable construction cost for each item of collection system rehabilitation recommended and compiles a total project cost in consideration of the non- construction costs associated with completing all of the proposed improvements as one project, should the City choose this route for budgeting and funding purposes. If complete-project funding cannot be procured, the rehabilitation can be completed incrementally as city funds allow, as each item works toward resolving one or more of the deficiencies identified. The unit costs associated with the rehabilitation efforts include consideration of the associated incidental items such as piping, pressure-testing, grouting, CIPP preparation, pipe bedding, and cleanup. The cost opinion presented in Table VIII-1 is based on available knowledge of the current bidding climate and is subject to change.

D. Funding Strategy and Impact on User Fees

Current residential sewer user rates are structured around per-month water usage volumes and charged under a single billing category for all sewer customers (residential, commercial, industrial, etc.). A base connection rate is applied regardless of volume used, with an additional cost, fractionally applied, calculated on each 1,000 gallons of metered water use. A summary of the City’s current billing rate structure effective as of February, 2015 is show in Table VIII-2.

TABLE VIII-2: CITY OF CASSVILLE CURRENT SEWER USER RATE SCHEDULE

Single Billing Billing Fee Category

Base Rate, Regardless of Volume $ 8.44

Cost per 1,000 gallons of Water Usage $ 6.67

Example Cost for 5,000 Gallons $ 41.79

Other revenues for the wastewater system include various account setup fees and late payment charges. The City should consider increasing the impact fee for new sewer connections, which currently consists of a $50 permit and inspection fee along with reimbursing the City its cost for the connection saddle materials. Impact fees should be assessed to bring equity between existing and new customers. By establishing and collecting cost-based impact fees, the City assures that “growth pays for growth” and existing utility customers will not have to shoulder an undue portion of the financial impact associated with new developments.

In consideration of the $5.4 million total project cost shown in Table VIII-1, if the entirety of this investment were to be financed through an increase in user rates, the monthly debt service per sewer connection would be approximately $22/month based on 1,600 connections and a 20- year loan term at 4.5% interest. With an existing monthly sewer bill of $41.79 based on 5,000 gallons of water use, the City may be able to position itself for some grant funding to complement the loan amount. Alternative funding sources and loan terms would of course alter the ultimate impact to user fees. Additionally, staging the project investment to first complete the public-side improvements before taking on the private I&I abatement program would allow the increase in sewer rates to be spread out over several years.

E. Proposed Rehabilitation Schedule

Based on the two 5-year plans outlined in this section and the associated financial impact and funding strategy needed to complete the recommendations, the following schedule is proposed for the City’s consideration:  January 2016 – Submit this report to MoDNR to fulfill the requirements of the Department’s Small Community Engineering Assistance Grant;

Project No. 014-2994 39 January 2016

City of Cassville, Missouri Wastewater Collection System Facility Plan

 Spring 2016 – Obtain 5-year time extension on VCA;

 Spring 2016 to Winter 2017 – City-performed rehabilitation and additional investigation with regards to stormwater impact on sanitary sewer flows;

 Spring 2017 – Hold bond election for sewer improvements funding, install permanent flow meter immediately upstream of WWTP influent lift station;

 Summer 2017 to Winter 2018 – Pending passage of bond election or other funding source, design sewer rehabilitation improvements;

 Spring 2018 to Winter 2020 – Construct sewer rehabilitation improvements;

 Spring 2020 – Conduct flow monitoring to measure impact of completed sewer rehabilitation improvements on I&I reduction, develop/finalize private I&I abatement program;

 Summer 2020 to Fall 2024 – Administer private I&I abatement program, obtain 5-year time extension on VCA, if needed;

 Spring 2025 – Conduct flow monitoring to measure impact of I&I reduction based on completed repairs/rehabilitation.

F. Conclusion

This facility plan presents a comprehensive Collection System Evaluation with recommended improvements to be completed over the next several years. The City requests that this evaluation and associated action plan replace the 2012 BEP submitted and approved over three years ago. During the last three years, a substantial amount of additional data was collected and analyzed to develop a more appropriate and specific strategy toward mitigating peak and prolonged wet-weather flows that could result in discharges from Outfall #002. This facility plan represents the City of Cassville’s new 5-year plan, and includes an additional five years of anticipated efforts to ensure the City is fulfilling its due diligence to eliminate bypasses from Outfall #002. Accordingly, the City respectfully requests the Department’s approval of the recommended plan of action and associated schedule over the next several years, and the replacement of the existing BEP with this facility plan.
