In the spring of 2015 RJN Group, Inc. was retained by the City of Coppell to perform a city wide flow monitoring study to establish dry and wet-weather flows and to identify excessive Infiltration and Inflow (I/I) or extraneous flow entering the system. Two sub-basins were identified as having excessive flow and as a result an evaluation of the sanitary sewer collection system by means of field investigations was performed on the interceptors with those areas. This technical memorandum contains the findings from the field investigations. Figure 1 depicts the study area. OVERVIEW A Sanitary Sewer Evaluation Study, or SSES, is a cost-effective method to evaluate the condition of sanitary sewer lines and access structures using various intensive field procedures and data analysis. Sewer lines are susceptible to I/I can be excessive, expensive to treat, and contribute to wet-weather overflows. Infiltration and Inflow may enter the sanitary sewer system during moderate storm events. Infiltration occurs when groundwater enters sewer lines and manholes. Inflow occurs when storm water runoff enters the sanitary sewer system through both public sector and private sector sources. Some inflow sources include cross connections with storm sewers, main line defects, vented manhole covers, defective frame seals, defective cleanouts, and direct connections to the sanitary sewer from downspouts and/or area drains. DESCRIPTION OF THE STUDY AREA In the spring of 2015 RJN Group developed basin boundary areas and performed flow monitoring throughout the City. Excessive I/I was identified in sub-basins COP-10 and COP- 14. After discussion with the City, it was determined that only the large diameter pipe lines located along nearby creeks be studied due to the potential to identify large I/I sources. The recommended study area included sewer infrastructure from Sub-basins COP-07, COP-10, COP-11, COP-14, and COP-15. The area is comprised primarily of residential neighborhoods and contains 75 manholes and 21,656 linear feet of sewer pipe. The study area runs along Denton Creek and Cottonwood Branch through Andrew Brown Parks which contribute flow to the Deforest Lift Station. PROJECT APPROACH The project approach for the City of Coppell Sewer study included conducting field investigations within the selected sub-basins and then developing a recommended plan to reduce I/I and improve efficiency of the wastewater collection system. The project team employed the following project approach for optimum results: TECHNICAL MEMORANDUM 2016 SSES PART 2A RJN Group, Inc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 Field Investigations: 1.

Closed Circuit Television (CCTV) Inspections Data Analysis and Recommendations: The recommended plan was formulated after carefully reviewing the results derived from the field investigation results and consists of the following: 1. Recommended I/I Removal 2. Cost to Implement the Recommended Plan DEFINITIONS AND ABBREVIATIONS This section contains definitions and abbreviations commonly used throughout this report. (1) Infiltration (as defined by USEPA) - the water entering a sewer system and service connections from the ground through such means as, but not limited to, defective pipes, pipe joints, service connections, service laterals, or manhole walls. (2) Inflow (as defined by USEPA) - the water discharged into a sewer system, including service connections, from such sources as roof leaders; cellar, yard, and area drains; foundation drains; cooling water discharges; drains from springs and swampy areas; manhole covers; cross connections from storm sewers, combined sewers, or catch basins; storm waters; surface runoff; or drainage. (3) Excessive Infiltration and Inflow (I/I) - the extraneous clean water that enters the sanitary sewer system which can be eliminated on a cost-effective basis. (4) Base Flow - wastewater flow exclusive of infiltration or inflow. Generally determined from water records during months when most of the water consumption is returned to the wastewater collection system. (5) Permanent Infiltration - extraneous flow that enters the sewer system through the ground during periods of dry weather/low groundwater. Generally determined by subtracting base flow during winter months from the average daily dry-weather monitored flow. (6) Peak Infiltration - the maximum extraneous flow that enters the wastewater collection system during high groundwater conditions after the inflow effects of a rain event have ended. Generally determined by subtracting dry-weather/low-groundwater flow (average daily dry-weather monitored flow) from flow recorded during periods of high groundwater. (7) Average Daily Dry-Weather Flow - dry-weather/low-groundwater flow exclusive of dry-weather/high-groundwater (peak infiltration) and wet-weather (inflow) flow. Includes base flow and permanent infiltration only.

MAPPING The City of Coppell staff provided map data of the wastewater collection system within the study areas at the initiation of the project that included existing access structures. Any manholes or other access structures found during field investigations that were not shown on existing maps were also assigned new numbers and GPS points were collected. FIELD INVESTIGATIONS Manhole and visual pipe inspection is the part of the survey where the physical condition of the sewer system is visually evaluated. These inspections verified manhole location, pipe size, line segment continuity, and evaluated manhole and adjacent pipe condition. A sectional elevation of a typical manhole is shown on the following page.

Location and identification number 2. Potential for ponding or sheeting on manhole cover 3. Cover type, fit, description, distance above or below grade, and evidence of inflow 4. Frame adjustment, seal, and evidence of inflow 5. Corbel construction, condition, evidence of inflow 6. Wall construction, condition, evidence of infiltration 7. Bench/trough construction, condition, deposition, evidence of infiltration 8. Pipe seal condition, evidence of infiltration 9. Step condition 10. Manhole inside diameter 11. Surcharging or evidence of surcharging 12. Indication of groundwater infiltration Inspections were performed on 66 of the 75 manholes (88.0 percent). A total of 9 manholes were unable to be inspected. Of the 9 manholes; access could not be obtained for 4 manholes, and 5 manholes could not be located. Every effort was made to locate and inspect every sanitary structure. Manholes not inspected are indicated on the manhole information report included in Appendix A. An access structure inspection summary is given in Table 1, while a summary of manhole defects is given in Table 2. Map Exhibit A shows the manhole inspection status. Manhole inspections resulted in the identification of 0.219 mgd of 1-year inflow and 0.024 mgd of infiltration. The largest contributors of inflow identified for this project were defective frame seals and manhole covers with pickholes. Field investigations identified 14 defective frame seals and 18 manhole covers with missing bolts and one (1) manhole wall that contributed approximately 0.211 mgd of inflow during a 1-year/60-minute rain event.

Field investigations identified eight (8) defective pipe seals contributing 0.012 mgd. Inflow and Infiltration rates can vary depending on the size of the defects and the number of defects found in a structure. The pressure head available from varying groundwater levels also can influence the rate of infiltration. The groundwater table is greater during the winter or after a spring or fall rainy season. Manhole SS1070 located in meter sub-basin COP-10 was identified as being the largest source of inflow. A large void with soil visible was identified at a joint and was estimated to be a source of approximately 0.144 mgd. Typically manhole walls are categorized as infiltration sources; however after multiple site visits this specific defect was identified to only be active after a significant rain event and was quantified as a direct inflow source from surface runoff. The photos below depict the location and observed inflow. The location of this manhole is shown on Figure 2. The City has engaged a contractor to address this structure. Surcharging evidence was identified at 5 manholes. Surcharging can be an indicator of silt/debris build up or collapsed sewer pipes that can ultimately lead to sewer overflows, or even capacity issues. The locations of these manholes are shown on Figure 3. A total of 5 manholes located throughout the study area indicated evidence of corrosion most likely from Hydrogen Sulfide gas (H2S). H2S can be attributed to long standing sewage due to insufficient slope, inverted siphons, pump stations and commonly occurs in turbulent water areas such as treatment facilities. H2S gases lead to corrosion within the sewer infrastructure. Penetration tests were performed at manholes with evidence of deterioration to determine the thickness of the corroded concrete found on the structure due to corrosive conditions and resulted in measurements from 0.08 inches to 0.50 inches. Corroded manholes are listed in Table 3 and shown on Figure 4. A detailed manhole inspection report is included in Appendix A. Area (COP-10) SS1070 Active Inflow (COP-10) SS1070 !. !.

Manhole identification numbers for connecting sewer lines. 2. Flow direction in pipes 3. Pipe diameter and construction material 4. Amount of root growth 5. Amount and type of deposition 6. Structural condition and line/grade of pipe 7. Visible infiltration in pipe and/or from pipe seals 8. Depth from manhole rim to each pipe invert 9. Recommended method of cleaning 10. Depth and velocity of flow Visual pipe inspection verifies pipe diameter, continuity, and aids in identifying pipe defects near the collection system access structure. Defects such as roots, joint offsets, circular/longitudinal cracks, and broken pipes are common among rigid pipe materials. Sewer lines observed in the study area are primarily constructed of PVC (76%), VCP (21%) along with a small amount of concrete pipe. A total of 174 pipes were inspected at the manholes where only two (2) pipes were found to be defective. A computer output report listing the findings of the visual pipe inspections is given in Appendix B. TELEVISION INSPECTION RJN reviewed data collected during field investigations and identified 18,869 linear feet of sewer line for television inspection. 2,787 linear feet was also selected for sonar inspection due to possible debris buildup in the pipe. Selections were based on results from pipe material, visual pipe defects, and locations of segments in or near low lying areas. Of the 18,869 linear feet identified, 58 line segments totaling 17,209 linear feet were able to be televised. A total of 1,660 linear feet was not inspected due to inaccessibility. A list of lines televised can be found in Table 4. Video review revealed five (5) segments of a totaling 2,370 linear feet show evidence of light roots. No immediate blockages of sewer flows are evident however it is recommended that the roots be treated and the segments be monitored again for maintenance within the next 5 years. Segment (COP-10) EOL-SS2167 was identified to have a large hole located 735 lf upstream from SS2167. This segment was under construction at the time of the inspection and has been fully replaced since the inspection. Sonar inspection was also conducted during the study as a method of inspecting full flowing sewer lines for the purposes of identifying debris and silt levels along with major pipe deformities. A total 6 line segments with an overall length of 2,787 linear feet were inspected using sonar technology. Results from the sonar inspections identified the lines to be clear of debris.

Inflow may enter the sanitary sewer system through directly connected downspouts, area drains, cleanouts, and building sewers. Inflow may also enter the system through direct or indirect connections between the sanitary sewers and storm drains or ditches, sewer line defects, and through defective manhole covers, frame seals, corbels and manhole walls. INFLOW SOURCE QUANTIFICATION All inflow sources identified during manhole inspections and television inspection were evaluated and quantified. Quantification of individual sources was based on a 1-year/60-minute storm and calculated using the orifice equation and rational formula. QUANTIFICATION PROCEDURE Inflow rates are typically determined by utilizing the rational equation, and the associated drainage area of each defect. The rational equation is as follows: Rational Equation: Q = CiA Q = Flow C = runoff coefficient i = Rainfall intensity A = Area Photos taken in the field assist engineers in the office to confirm the drainage area, the intensity of the smoke, and the ability of the defect to pond (rainwater pooling over a defect; ponding depth is estimated in the field). If a defect is determined to have the capability of ponding, the orifice equation can be used to determine the inflow rate. Typically, the lowest inflow rate is assigned to the defect when comparing the orifice equation to the rational equation. Orifice Equation: Q = CdA(5.37h)0.5 Q = Flow Cd = Coefficient of Discharge h = Height or head The total quantified inflow from all sources identified through field investigation was estimated to be approximately 0.291 mgd during a 1-year/60-minute design storm. The largest contributors of inflow to the sanitary collection system are defective frame seals, one (1) manhole wall and one (1) defective pipe with holes. Ninety (90%) of inflow in the study area is attributed to these source types. Due to the nature of the manhole wall and pipe defects it was determined that these two sources are direct sources of inflow which allow for significant amounts of excess flows to enter the system and were quantified as such. A summary of inflow sources is provided in Table 6 and is shown graphically on page 16. A detailed list of each source is also provided in Appendix E.

Two types of infiltration can be determined during a study, permanent infiltration and peak infiltration. Permanent infiltration is defined as extraneous flow that enters the system through the ground during periods of dry- weather and low -groundwater. Peak infiltration is defined as the maximum extraneous flow Table 6 Distribution of Inflow Sources Source Quantity 1-Year/60-Minute Projected Peak Inflow (mgd) Percent of Inflow Manhole Defects Inflow Defective Frame Seals 14 0.037 12.71 Broken Frame 1 0 1/ 0.00 Manhole Corbel Defects 4 0.007 2.41 Defective Covers 1 0.001 0.34 Covers Missing Bolts 18 0.030 10.31 Defective Manhole Walls 1 0.144 49.48 Subtotal 39 0.219 75.26 Pipeline Defects Inflow Defective Pipe With Hole 1 0.072 24.74 Total 40 0.291 100.00 1/ Approximately 173 (gpd) 13% 0% 2% 0% 10% 50% 25% Distribution of Inflow Sources Defective Frame Seals Broken Frame Manhole Corbel Defects Defective Covers Covers Missing Bolts Defective Manhole Walls Defective Pipe With Hole RJN Group, Inc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 that enters the sewer system during high-groundwater conditions after inflow effects of a rain event have ended. Analyses of wastewater infiltration were based on I/I source data from field investigations, specifically manhole and visual pipe inspection, and internal television inspection of sewer lines. INFILTRATION SOURCE QUANTIFICATION Each of the infiltration sources identified during field investigations was evaluated and quantified in reference to the corresponding sub-basin and line segment. The infiltration rate was estimated based on the severity of the defect. A potential infiltration rate was estimated for each manhole and pipe defect that was observed but not actively leaking. The sum of all observed infiltration sources is referred to as total identified infiltration. Total identified infiltration was quantified to be 0.038 mgd. Defective pipe seals were identified as the largest source which contributes approximately thirty-one (31%) of the total identified infiltration. The total identified infiltration is summarized by source type in Table 7 and is shown graphically on page 18.
