Phase 1 of the study consisted of developing basin boundary areas and performing flow monitoring throughout the City. The purpose of the flow and rainfall monitoring was to establish dry and wet-weather flows within the system and prioritizing those areas with excessive amounts of inflow and infiltration. Wet-weather flows were analyzed to determine which areas of the system contribute excessive infiltration/inflow (I/I) to the sewer system. This report addresses the results of the Phase 1 flow monitoring activities. PROJECT APPROACH RJN Group, Inc. conducted flow monitoring program during the spring of 2015. The gravity portion of Coppell, Texas’s sanitary sewer system was divided into twenty two basins for the purpose of evaluating flow characteristics in each area. Table 1 provides a summary of each basin and associated footages that are contained within each sewershed. The project scope consisted of flow and rainfall monitoring for seventy one (71) days at twenty two locations. Twenty two (22) flow meters and seven (7) rain gauges were installed between May 14 and May 22, 2015 with the beginning of the flow monitoring period starting on May 23, 2015. Due to an unseasonably wet spring season, multiple rain events were accounted for within seventy one (71) days from the start of the flow monitoring period. Although the original scope requested 60 days of flow monitoring, after discussion with the City, it was determined that additional monitoring was required to obtain a representative sample of dry weather flow. The flow monitoring was extended by eleven (11) days and concluded on August 1, 2015. Table 1-B lists the meter locations by site name and pipe dimensions. The height/width of opening, as indicated on the table, is the measured pipe dimension and does not reflect the nominal pipe size. This is due to deflections that occur at the mouth of a pipe during manhole installation. The measured pipe diameters/heights ranged from approximately 10-inches to 49-inches. Exhibit 1 outlines the flow meter locations, rain gauge locations, and basin boundaries. A basin flow diagram indicating direction of flow from one basin to another is shown on page 1-4. Flow meters were used to record depth and velocity of flow at five-minute intervals. Engineering review and input of additional calibration data was used to finalize the metered flow data. Manual depth and velocity readings (velocity profiles) were taken bi-weekly to verify the metered data. Average flow rates for one-hour intervals were determined for each monitoring location. The average hourly flow rates were used to determine daily dry-weather INTRODUCTION 1 C H A P T E R RJN Group, Inc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 - 2 and wet-weather flow rates.

Once the preliminary manhole was identified for a meter site the manhole was investigated to determine if the site had good hydraulics which is a key for collecting high quality and accurate flow data. In general, it is preferred to have a straight channel where flow is free of turbulence or backwater effects. In some sites it was necessary to install meters where a slight bend in pipe direction existed or the optimum flow characteristics were not prevalent. This was because the location was strategic to the monitoring program. Listed below are other considerations that were investigated before the sites were installed: •Installation constraints • Manhole configuration •Silt deposition •Pipe dimensions •Flow depth range •Maintainability •Site accessibility •Velocity range •Telemetry constraints •Site specific concerns • Employee safety •Sensor survival •Manhole accessibility • Surcharging evidence Where necessary, the City assisted RJN in locating manholes and providing accessibility. A copy of the Meter Site Installation Forms complete with photos for each meter location, are provided in Appendix A. The photos of each meter site include the site location, inside manhole, and pipe before and after sensor placement. FLOW METER TYPE INFORMATION The FlowShark Triton and Triton+ meters were selected as the gravity flow meters to complete the flow monitoring program. The average accuracy of the meters for the depth measurement is ±0.15 inches and the average accuracy for velocity is ±0.04 fps. ADS FlowShark Triton meters were installed in (11) locations and ADS Triton+ meters were installed in the remaining (11) locations. Some information regarding the selected flow meter is included on the following pages: DATA COLLECTION AND EQUIPMENT C H A P T E R 2 RJN Group, Inc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 - 2 Triton Meter Principles: The ADS Triton meters are open channel flow meters that utilize Doppler ultra sound technology to sense the peak flow velocity, as well as a redundant depth sensor. The ADS Triton has four primary components: a logger unit that stores the collected data and houses the RTU, the Ultrasonic Depth Sensor, Peak Combo Sensor, and the integrated wireless modem. The Peak Combo Sensor typically mounts at the bottom of the pipe and measures an upward-looking ultrasonic depth, pressure depth, and peak velocity using three independent sensors. One of the three sensors in the Peak Combo Sensor utilizes a pressure transducer to measure pressure depth which will record water level including full pipe and surcharge level. The Ultrasonic sensor is a non-instrusive quad redudant transciever sensor which will accurately record the depth to within one inch of the sensor’s face. The sensors emit signals and receive returned signals from the flow to capture the characteristics of the flow velocity and depth. During surcharged conditions the ultrasonic depth sensors no longer functions, and the level is recorded through the Peak Combo Sensor that contains the pressure sensor. Flows are calculated using the continuity equation. Flows are calculated using the continuity equation, which is expressed as Q = AV, where Q is flow, A is the cross sectional area, and V is the average velocity of the flow. The meter records velocity and depth at five-minute intervals. Triton Calibration and Installation: The ADS Triton must be calibrated on site by entering physical offsets of the sensors and their positions in the meter as well as comparing the depth and velocity measurements recorded by the meter to manual measurements. Depth and velocity adjustments for the ADS Triton are made directly to the meter as necessary. The meter housing was secured to the steps or with an eyebolt on the frame of the manhole. A stainless steel, expandable band secured the depth/velocity probe to the channel. The probes were positioned in the flow of the incoming pipe to minimize the effects of flow turbulence and debris buildup that may exist in the manhole. TELEMETRY EQUIPMENT Each Triton flow meter called into a central processing location during the project to perform a data dump for data collection and review. This process was done through a Remote Figure 2.2: Flow is calculated using the Continuity Equation: Flow = Average Velocity x Area of Flow Figure 2.1: FlowShark Triton, Ultrasonic Depth Sensor, and Peak Combo Sensor RJN Group, Inc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 - 3 Transmission Unit (RTU) that collects data and sends the collected data by wireless telemetry to the central processing location. The data was then available for review on the website hosted by RJN. Each RTU initiated a call into the central location once every 24 hours. The RTU’s transmit all of the 5-minute data points recorded that day. The antennas were typically located just outside the manhole because a cast-iron manhole cover would block the wireless signals otherwise. The antennas were buried just below the existing surface and covered with traffic approved material. A typical installation is shown in Figure 2.3. METER MAINTENANCE During site visits, data stored in the meter was manually retrieved as a backup to the telemetry download and the meters were inspected to ensure proper operation. The meter depth and velocity readings were taken before and after maintenance/cleaning of the probes. Manual depth and velocity measurements were taken, silt deposit depths were recorded, and if necessary, the batteries were changed. Typically, one (12) twelve-volt battery lasted an average of four weeks due to the RTU drawing power from the batteries. Offset adjustments were recorded in the site specific meter maintenance log. Ten (10) of the twenty-two (22) sites contained some silt. Site COP-14 contained the highest silt with an average silt depth of 3.83 inches and a maximum recorded silt depth of 5.00 inches. Site COP-02 contained the second highest silt with an average silt depth of 2.58 inches and a maximum recorded silt depth of 3.00 inches as well. RAINFALL MONITORING Seven (7) temporary rain gauges maintained by RJN Group, Inc. were utilized to monitor rainfall during May 23, 2015 through Aug 1, 2015. Exhibit 1 shows the location of the temporary rain gauges. Rainfall was recorded with a continuously recording rain gauge with an accuracy of 0.01 inches. The rain gauge was equipped with a separate RTU and called in once per day to relay data to the central database. Rainfall Results: Spring 2015 was an exceptionally wet season with many rain events close to a 1-inch of rainfall for a 24-hour period; however, there were only a few rain events that surpassed a 1.0 in/hr intensity. Rain gauge 05 recorded six (6) rainfall events of greater than 1-inch of rainfall for a 24-hour period. All remaining rain gauges recorded seven (7) rainfall events of greater than 1-inch of rainfall for a 24-hour period. Rain gauges 01, 02 and 06 recorded the largest rainfall on May 29, 2015. The other four rain gauges 03, 04, 05 and 07 recorded largest rain even on May 24, 2015. Rain gauges 01, 02 and 06 highest intensity rainfall occurred on May 29, 2015. Rain Gauge 01 recorded a peak 1-hour intensity of 1.81 inches per hour and total rainfall of 2.59 inches. Rain Gauge 02 recorded a peak 1-hour intensity of 2.09 inches per hour with a Figure 2.3: Typical meter installation RJN Group, Inc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 - 4 total rainfall of 2.89 inches.

Rain Gauge 03 had a peak -hour intensity of 1.85 inches per hour with a total rainfall of 1.91 inches. Rain Gauge 05 had a peak 1-hour intensity of 2.23 inches per hour with a total rainfall of 2.33 inches. Rain gauge 04 and 07 highest intensity rainfall occurred on May 24, 2015. Rain Gauge 04 had a peak 1-hour intensity of 1.55 inches per hour with a total rainfall of 2.59 inches. Rain Gauge 07 had a peak 1-hour intensity of 1.58 inches per hour with a total rainfall of 2.39 inches. The rain gauge recorded totals and intensities are listed in Table 2-A. The 5 minute electronic excel data is provided with this report. EXISTING METER INSTALLATION CHECK RJN Group performed a site visit to the TRA MS17.0E Meter Station to collect field measurements regarding the dimensions of the meter station vault and placement of the meters within it. Based upon prior discussions with TRA staff the exact model of the installed meters were unknown although the manufacturer of the meter is Eastech Flow Controls. The site inspection was unable to determine a specific meter model number in use, although the models installed on siphon Pipes 1 and 3 including prefabricated spool pieces which are very similar to the current Eastech Vantage 4800 Single Spool Construction standard transit time flowmeter model. Per the Eastech manufacturer specifications and installation recommendations, this model of transit time meter requires an equivalent straight run distance of ten (10) to fifteen (15) pipe diameters (d) upstream and two (2) to three (3) diameters downstream from the meter to any significant system turbulence in order to obtain maximum published meter precision and accuracy. Therefore based on manufacturer’s recommendations, the transit time meters installed at TRA MS17.0E should be located at least 15 feet (22.5 feet is preferred) from any upstream and 3.0 feet (4.5 feet is preferred) from any downstream sources of turbulence to obtain the published maximum precision and accuracy of this meter. RJN collected field measurements regarding the placement of the two existing transit time meters in the meter station vault. The current placements of these meters are 17.3 feet from the upstream and 3.2 feet from the downstream interior vault faces. Based upon the field measurements the upstream and downstream straight run distance from the meters to any type of flow turbulences appear sufficient (meet the minimum) in order to obtain the published meter precision and accuracies. Note that RJN does not consider the existing flow transition Transit meter location in valve vault RJN Group, Inc. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 - 5 boxes located upstream and downstream of the MS17.0E meter vault to be part of the turbulence free zones when evaluating straight runs of pipe for published optimal metering. Also note that even though field observations of these flow control boxes did not display significant signs of visual turbulence, the presence of a hydraulic slide component included in each box design creates some base level of flow turbulence and thus, should not typically be included in straight meter run analysis. (If we include the vault wall thicknesses and width of these control boxes with the straight pipe run distances noted above, the computed straight run distances would be 22.55 feet and 8.25 feet, respectively, and exceed the published “preferred” straight run distances for this meter.) RJN also identified approximately 6” of silt depth in both the incoming pipes at the upstream transition box as well as 6-8” of silt in the outgoing pipes of the downstream transition box. No silt was observed on the upstream incoming pipes to the siphons although 3” of silt was measured at the downstream end of the Meter 3 siphon. The presence of silt will contribute to flow turbulence, odors and corrosion. Additionally, it may also be indicative of insufficient recurring scouring velocities being achieved and traveling through the metering pipes. Based upon the field visit, RJN observed that the manhole lid on the structure immediately upstream of the meter station was deteriorated to the point of allowing sewer gases to escape through the pick concealments. Other than the items described above RJN did not determine any significant issues regarding this meter station.

Peak infiltration is defined as the maximum extraneous flow that enters the sanitary sewer system during high-groundwater conditions after the inflow effects of a rain event have ended. DETERMINATION OF PEAK INFILTRATION Determining peak infiltration requires analysis of flow data obtained during dry-weather/high-groundwater conditions. Care must be exercised in the analysis to exclude days that are too close to rainfall events to avoid including residual inflow (rainfall induced infiltration) that may lead to an over-estimation of peak infiltration. Generally, periods following significant rainfall, excluding the day immediately following a rain event, are used for determining peak infiltration. Average dry-weather/high-ground water flow was determined using hourly flows during high -groundwater periods. Average peak monitored infiltration was determined by subtracting the average dry-weather/low-groundwater flow from the average dry-weather/high-groundwater flow. Peak infiltration during the study period was determined to be 2.531 mgd in the study area. A summary of peak infiltration for each monitored basin is given in Table 3-C and shown graphically on the following page. The peak basin unit infiltration rate expressed in gallons per day per inch diameter miles, also given in Table 3-C, is a method of expressing the magnitude of peak infiltration relative to other basins. A basin flow diagram also giving peak monitored infiltration is shown on page 3-8. Basin peak infiltration was calculated using inch diameter miles (idm). To determine gpd/idm, the total inch diameter-miles of pipe were calculated for each pipe size in their respective basin. The basin peak infiltration was then divided by the total inch miles. Excessive infiltration occurs when the basin peak infiltration is greater than 5,000gpd/idm. Infiltration was found to be negligible for basin 02, 07, 10, 16 and 18. Basin 14 has excessive infiltration with over 20,000gpd/idm. Basin 03, 04, 05, 06, 13 and 17 had the highest infiltrations with over 1,000gpd/idm while the rest of the basins had less than 900 gpd/idm of infiltration.

Peaking factors ranged from 2.14 to 6.98 and are provided in Table 4-A on page 4-2. A wet-weather peaking factor under 5.00 is considered acceptable. WET FLOW HYDROGRAPHS VERSUS RAINFALL: The wet-weather peaking factor was calculated based on the total flow rate observed for the June 17, 2015 storm. The rain event started on June 17 at around 4 AM and carried on for about 13 hours. July 25–July 31 was used as a dry weather period for calculation of average daily dry weather flow for most of the flow meter sites except July 26 – August 1 was used for flow meter site COP-02. Table 4-A shows the largest peaking factor was 6.98 and occurred at meter site COP-14. INFLOW CONDITIONS Inflow in a sanitary sewer system is defined as extraneous flow that is a direct result of stormwater runoff. Inflow may enter the sanitary sewer system through directly connected downspouts, area drains, cleanouts, and building sewers. Stormwater 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. DETERMINATION OF INFLOW The scope of services for this project included developing a relationship between inflow and rainfall intensity (Q vs I). This is generally performed by plotting peak inflow against the 60-minute rainfall intensity for the corresponding rain event and then using regression analysis to determine the "best fit" relationship between the various sets of data points. Several storm events of various intensities that do not surcharge the sewer system are required to establish the inflow/rainfall intensity relationship. The quick surcharging of the sewer collection system during most rain events increased the difficulty of the inflow analysis.

However, due to some rain events occurring in rapid succession only a select few were valid for analysis. Based on the analysis performed on the all meter basins, it is concluded there is an excess of inflow for approximately 40% of the monitored system. Based upon the rainfall induced peak analysis, infiltration is excessive at COP-14 and significant at COP-03 and COP-10. POTENTIAL PLAN The potential plan consists of a more detailed Sanitary Sewer Evaluation Study (SSES) in meter basins that exhibited an above industry standard amount of acceptable inflow and infiltration in order to identify as many sources of I/I as possible. The industry standard of acceptable inflow is 10,000 gpd/1,000 lf of sewer pipe and 5,000 gpd/idm for infiltration. Nine (9) out of the twenty-two (22) basins experience excessive inflow. Inspecting all recommended basins at one time may not be practical, in which case basins have been prioritized according to the severity of I/I, starting with basins with the highest inflow as Priority 1. A detailed breakdown of the twenty two basins can be found in Table 5-A and is sorted from highest priority to lowest priority. A summary of the recommended basins by priority can be found in Table 5-B listing the basins in order of priority for further investigation and graphically in Exhibit 3. The potential plan for Phase 2 consists of 3 years of study and is shown on Table 5-C and graphically on Exhibit 4. Upon completion of the SSES and any subsequent rehabilitation, post rehab flow monitoring is recommended to be performed in order to evaluate the work and quantify the reduction of inflow.
