These modeled areas contain all the parameters for loading flow into the sewer network including population, non-residential flow, and Rainfall Derived Inflow/Infiltration (RDII) runoff parameters. As part of this study, the existing sub-catchments were preserved, and new sub-catchments were created based on the property parcel data provided by Garland County. Loading flow from individual parcels provides a better distribution of dry and wet-weather flows into the sewer network and eliminates time of concentration assumptions. Going forward, having sub-catchments based on individual property parcels is very useful for tracking and assessing the impact of redevelopment sites, e.g., demolition of four houses for a 50-apartment development. The updated sub-catchments comprise areas that contribute flow into the sewer system. Areas such as parks, golf courses, cemeteries, etc. that are not connected to the sewer system were not imported from the parcel data as they do not contribute any wastewater flow or RDII. The hydraulic model contains 28,642 sub-catchments with an average size of 0.503 acres. The creation of new sub-catchments in the model also provided the opportunity to capture areas of new development that were not present in 2015. Residential Flow Updates Residential dry-weather flows are generated in the model based upon population and winter water usage records from CHS. Population data was sourced from the 2010 Census and projected to match current population estimates. Households were located within the collection system using the residential customer billing data (points) from the CHS GIS. Populations were assigned to individual
MODEL DEVELOPMENT Page 3-4 households (customer billing points) within each Census block. The populations from the customer billing points were then totaled within each modeled sub-catchment. The total current population in CHS is estimated at 38,560. Commercial/Institutional/Industrial Loading Commercial, institutional, and industrial flows were loaded into the model using the customer water billing data provided by CHS. The commercial, institutional, and industrial flows were calculated assuming a 90% return to sewer factor to the water usage data. Model Testing A series of validation tests were undertaken on the model to confirm logical network connectivity as well as consistent vertical alignments. A standard residential hydrograph was applied to each sub-catchment in the model and validation simulation undertaken. After a few minor alterations, the model was able to be run for a 24-hour dry-weather simulation without any issues and was considered a stable platform for calibration to proceed. Model Calibration Process Model calibration is necessary for the model to accurately represent the behavior of the wastewater collection system. Model calibration is a process through which model variables and coefficients are adjusted through multiple iterations until flow, depth, and velocity matches within a reasonable accuracy to the actual flow meter recorded data. The model is calibrated to recreate sewer performance in both dry-weather and wet-weather conditions. The flow survey data is not used as an input to generate flow in the hydraulic model. Model predicted flows and depths are compared with the flow survey data and adjustments are made to the model until a satisfactory fit is achieved. Dry-Weather Period Dry-weather calibrations ideally require at least a seven-day period, including one weekend, unaffected by rainfall induced flows. The recorded flow data was assessed in conjunction with the rainfall data, and the period April 7, 2021 through April 14, 2021 was selected as the most representative dry-weather period. Using flow data collected from the flow meters, weekday and weekend dimensionless diurnal profiles were developed through a process of groundwater subtraction and normalization. From this process, multiple residential flow profiles were created that were used to best fit the model predicted data to flow monitoring data. These profiles were input into the model and used to modulate dry-weather flows. Figure 3.2 on page 3-3, graphically depicts the residential flow profile that was most used.
MODEL DEVELOPMENT Page 3-5 Residential flows were initially estimated with an assumed daily flow of 60 gallons/person/day. These values were then adjusted from 60 to 80 gallons/person/day as required during calibration to match the recorded volumes at the flow meters. Non-residential flow volumes were initially estimated based on a 90% return rate to sewer of water consumption and assigned a diurnal distribution pattern representative of the predominant type of business or industry in each sub-catchment as determined during model construction. Commercial and industrial areas produce flow patterns that are unique from residential areas. A set of standard profiles were used for commercial and industrial areas. The profiles were assigned based on the predominant type of business or industry present in each sub-catchment, as determined during model construction. Figure 3.2 – Residential Profile
MODEL DEVELOPMENT Page 3-6 Figure 3.3 on graphically depicts examples of both commercial and industrial flow profiles used in the model. Modifications to the following were made to calibrate the model for dry-weather flow: Permanent groundwater infiltration rates Per capita flow rates/curves Commercial/industrial flow rates/curves Through a time-intensive and iterative process, residential and non-residential factors were adjusted, and base flow (permanent infiltration) was included, as necessary, until the model reasonably reflected the dry-weather flow regime over a week at each monitoring site, as illustrated in the following Figure 3.4. The blue trace represents the recorded data with the green trace representing the modeled flows. Figure 3.3 – Commercial and Industrial Profile

MODEL DEVELOPMENT Page 3-8 Wet-Weather Calibration Wet-weather flows are generated within the model by assigning the recorded time series of rainfall from a nearby rain gauge to each model sub-catchment and combining with hydrological parameters to reflect the system response to rainfall. To achieve a suitable level of calibration, it was necessary to iteratively adjust the hydrological parameters and compare with the recorded flows and surcharge depths at each meter site. Wet-weather flows were generated in the model using both fixed response surfaces as well as infiltration flows: Up to three “fixed” response surface areas were calibrated for each sub-catchment. These surface types are fundamentally independent of the catchment condition prior to the rainfall event and represent fast responses from areas such as illegally connected roof drainage and stormwater cross connections. Rainfall induced infiltration was modeled using the hydrology in the Ground Infiltration Module (GIM) within InfoWorks. This hydrological module has soil and groundwater storage zones, and inflow into the model is dependent upon the wetness of the catchment prior to the rainfall event, considering both preceding rainfall and evaporation. These flows represent the delayed ingress of rainwater through the ground into the sewer system through cracks and leaks in sewers and private drains. Following each of the rainfall events, many of the basins took several days for the flows to recede back to the normal dry-weather pattern. In some cases, the flows were still elevated when the response from a following storm came through. Wet-weather calibration was undertaken by simulating the model over the full survey period to achieve a good match with flows as well as surcharge depths at the peak of the storms. Overall, the calibrated model provided an accurate representation of the current flows and system hydraulics. Figure 3.5 illustrates model calibrated flows (shown in green) of two storm events recorded during the flow survey period (shown in blue).

CAPACITY ANALYSIS Page 4-1 Summary This chapter provides a summary of the capacity analysis undertaken on the existing system when subjected to rainfall from the design storm event. The primary purpose of the analysis was to determine the proper capacity improvement projects required to eliminate the remaining wet-weather Sanitary Sewer Overflows (SSOs) in the Hot Springs sanitary sewer system. The downstream effects at Davidson Wastewater Treatment Plant (DWWTP) were also analyzed to ensure the treatment plant would not be overwhelmed at any part of the treatment process. Existing System Analysis Dry-Weather Flow System Performance There are no hydraulic issues in the system under dry-weather conditions. Inflow and Infiltration 32 of the 44 metered basins experience high wet-weather peaking factors in response to rainfall. Figure 4.1 illustrates an example hydrograph of the wet-weather response to rainfall recorded at meter basin HS-42 for the rainfall events occurring on May 17, 2021 and May 20, 2021. The shaded green area represents the dry-weather flows with the shaded blue area defining the wetweather flows that were recorded following the storm events. This hydrograph illustrates a few of the key issues noted in the Hot Springs sanitary sewer system: Figure 4.1 – Wet-Weather Hydrograph
CAPACITY ANALYSIS Page 4-2 The minimum overnight flows during dry-weather periods exhibit a high level of permanent infiltration. The initial wet-weather response to rainfall is a mixture of quick entry and slow entry response sources. However once flows peak, the response takes many days, in some cases up to a week, for the flows to return to near normal dry-weather patterns. This indicates that flows conveyed to this meter have not only inflow issues, but also infiltration problems. Operational Assumptions In addition to the geometry updates, the model has been refined to reflect the operational performance of the major pump stations more accurately such as Stokes pump station, Hot Springs Creek pump station (HSCPS), and the DWWTP in dry and wet-weather conditions. Based upon discussions with City of Hot Springs (CHS) operating staff and Crist Engineers, the following operational rules were implemented: Pending capital improvements currently under design at DWWTP will provide a seven-day rated capacity of 24-MGD. Drain back from the equalization (EQ) basin should commence when flows reduce to 20-MGD. A flow splitting structure post preliminary treatment diverts 24-MGD to the biological process, with up to 24-MGD diverted to tertiary filters. When flow exceeds 48-MGD it is diverted prior to preliminary treatment to the EQ basin, which can store 80-MG. During wet-weather at Stokes pump station, “Stokes 3” pump and the “Godwin” diesel pump use the “old” Stokes force main to send flows toward meter site HS-50 during peak flow conditions. “Stokes 1” and “Stokes 2” pumps send flows down the new Stokes force main. During wet-weather at HSCPS, three “Flygt” pumps send flow through the 36-inch Fairwood force main, which discharges directly into the headworks at DWWTP. And the “Godwin” diesel pump sends flow down the 30-inch Hot Springs Creek (HSC) force main towards meter site HS-54. Existing System Analysis Design Storm The 2010 SECAP design storm accepted and approved by CHS and Environmental Quality Division of the Arkansas Department of Energy and Environment in the Consent Administrative Order (CAO) was used for the analysis. This storm is a theoretical storm event in which a total of 4.3-inches of rainfall falls over 24-hours and has a peak one-hour intensity of 1.94-inches. The design storm event was updated with more accurate temporal distribution from NOAA’s Atlas 14. The model was first initialized with six months of recorded historical rainfall preceding the design storm to establish the soil saturation level at the onset of the event. The saturation results from the initialization event were imported into the design storm simulation and the model was run for a seven-day period. Design Storm Results The design storm analysis indicated a high correlation with the documented overflows in the Hot Springs sewerage area. The analysis also indicated that several projects recommended in the 2010 SECAP Update are still necessary and may have expanded in size due to additional extraneous flow entering the system since the 2015 model recalibration. These include the Lakeside pump station tributary capacity improvements, HSC Interceptor and pump station upgrade, and the Gulpha Interceptor and pump station upgrade projects.
CAPACITY ANALYSIS Page 4-3 Determination of Required CIP Projects All wet-weather SSOs from 2020 and 2021 were assigned to a capacity improvement project to eliminate those SSOs. Table 4-A summarizes the wet-weather SSOs from 2020 and 2021 provided by CHS. The proposed capacity improvements were incorporated into a SECAP version of the hydraulic model and tested against the design storm to ensure the improvements would eliminate the recorded SSOs. Hot Springs Creek (HSC) Tributary The Lakeside pump station tributary is a small sub-tributary located within the HSC tributary. There are currently two wet-weather SSOs related to capacity issues within the Lakeside pump station tributary. MH 5259 and 5260 overflow regularly with MH 5259 being the single most recorded SSO location throughout 2020 and 2021. Over the two-year time span, MH 5259 experienced 29 wet-weather overflows. To eliminate overflows at MH 5259 and 5260, gravity main upsizing is necessary directly upstream of the Lakeside pump station. Increased pumping capacity at the Lakeside pump station and force main upsizing is also necessary. The Lakeside pump station has a current pumping capacity of approximately 1.30-MGD but experiences roughly 2-MGD of peak flow during the design storm. A relatively short section of gravity main sewer totaling 1,095 LF will need to be upsized from eight and 10-inch diameters to 15 and 18-inch diameter. Upsizing this section of gravity main will consequently deliver more flow to the Lakeside pump station during the design storm, which will in turn require Table 4-A WET-WEATHER SSOs 2020-2021 Manhole Number Associated Tributary Number of Occurrences 2020 & 2021 161 Hot Springs Creek 1 165 Hot Springs Creek 1 1684 Hot Springs Creek 1 1750 Gulpha 27 1754 Gulpha 16 1755 Gulpha 1 1864 Hot Springs Creek 4 1865 Hot Springs Creek 5 1866 Hot Springs Creek 4 4117 Gulpha 9 4118 Gulpha 14 5259 Hot Springs Creek 29 5260 Hot Springs Creek 17 9250 SWWWTP/Mazarn 11 9292 SWWWTP/Mazarn 1 10578 Gulpha 8 12242 Hot Springs Creek 7 13483 SWWWTP/Mazarn 16 13484 SWWWTP/Mazarn 18 39025 Stokes Pump Station 7
CAPACITY ANALYSIS Page 4-4 upgraded pumping capacity of 4-MGD. The discharge force main from Lakeside pump station is currently eight inches in diameter and manifolds into the 30-inch Hot Springs Creek force main. Increasing the pumping capacity at Lakeside pump station to 4-MGD would require the Lakeside force main to be upsized from eight-inch to 15- inch diameter, to maintain velocities under eight feet-per-second during the design storm. RJN is proposing a shorter force main alignment that manifolds into the 30-inch Hot Springs Creek force main approximately 120 feet south of the Lakeside pump station. There are negligible differences in static head in the proposed force main alignment compared to the existing alignment. Approximately 1.1-MG of additional flow would reach the DWWTP during the design storm over a five-day period under these conditions. Figure 4.2 shows the extent of the upgrades within the Lakeside pump station tributary and the proposed force main alignment symbolled with a purple line. Table 4-B summarizes the cost estimate for the upgrades in the Lakeside pump station tributary.

CAPACITY ANALYSIS Page 4-5 Six of the nine wet-weather SSOs recorded in the HSC tributary are attributed to capacity issues along the HSC interceptor and/or at the HSC pump station. These include MHs 161, 165, 1864, 1865, 1866, and 12242. MHs 161 and 165 overflowed the least number of times, with only one overflow recorded at each location throughout 2020 and 2021. MH 12242 overflowed the most within the HSC tributary with seven occurrences recorded throughout 2020 and 2021. The SSOs occurring at MHs 161 and 165 are due to capacity restraints along the upper section of the HSC interceptor starting south of East Belding St. at MH 1134 and ending at MH 1912. This section of gravity main is 8,302 LF, currently 27 inches in diameter, and services a large portion of the HSC tributary. Figure 4.3 depicts the area that the 27-inch section of the interceptor is servicing. This area includes a large portion of the downtown Hot Springs area which has a high density of restaurants, businesses, and residential housing as well as the Oaklawn Racetrack and Casino. The 2010 SECAP report recommends that the 27-inch section of the HSC interceptor be upsized to 36 and 42-inch diameter gravity main to eliminate the SSOs at MH 161 and 165. The SSOs occurring at MH’s 1864, 1865, 1866, and 12242 result from a combination of undersized interceptor near the HSC pump station and pumping capacity limits at the HSC pump station. The lower section of the HSC interceptor, starting at MH 1912 and ending at the HSC pump station, is 2,635 LF, currently 36 inches in diameter, and would require upsizing to 48 inches to convey peak flow during the design storm without surcharging. Currently, the HSC pump station has a maximum pumping capacity of approximately 36-MGD. Subsequent of upsizing the HSC interceptor, the hydraulic model predicts a peak flow rate of approximately 53-MGD reaching the HSC pump station during the design storm. New pumps with a total pumping capacity of 51-MGD would be required to handle peak flow. Figure 4.3 – Area Serviced by 27-inch Interceptor in HSC Tributary
CAPACITY ANALYSIS Page 4-6 Due to budgetary constraints and the potential of overwhelming the Davidson Wastewater Treatment Plant, RJN is recommending a systematic approach to reducing the amount of extraneous flow entering the sewer system within the HSC tributary in lieu of major capacity improvements. This may include Closed Captioned Televising (CCTV) investigations of the HSC interceptor and its major interceptors to locate potential large sources of I/I and an SSES study within the HSC tributary to facilitate I/I reduction. Once these reductions are completed, it is recommended to reevaluate the need for the capacity improvements along HSC. Only one SSO was recorded at MH 1684 in February 2020. The hydraulic model does not show any capacity issues upstream or downstream of this manhole. This SSO may have occurred from temporary blockages in the gravity main that have since resolved themselves. Additional monitoring of this manhole after storm events is recommended and CCTV investigation may be required if an overflow occurs in the future. A 30% I/I reduction was applied to sub-catchments in the hydraulic model within the area shown in red in Figure 4.3, shown on page 4-5, with no upsizing of the HSC interceptor or HSC pump station. After running this option with the design storm in the hydraulic model, all SSO locations were eliminated except at MH 161. Southwest Wastewater Treatment Plant (SWWWTP)/Mazarn Tributary The Mazarn tributary consists of multiple major and mid-major pump stations that route flow through a series of gravity mains and force mains. All flow from the Mazarn tributary is currently pumped to the South Rogers pump station, which then pumps to the Winkler Road pump station before discharging into SWWWTP. Figure 4.4 on page 4-7 illustrates the current routing of sewer flow through the Mazarn tributary to the SWWWTP. Four SSO locations were recorded throughout 2020 and 2021 at MHs 13483, 13484, 9250, and 9292. MH 13483 and 13484 were recoded to have 16 and 18 SSO occurrences respectively and MH 9250 and 9292 were recorded to have nine and one SSO occurrences respectively throughout 2020 and 2021. Figure 4.5 on page 4-7 shows the locations of the recorded SSOs within the Mazarn tributary. To eliminate the four recorded wet-weather SSOs in the Mazarn Tributary, RJN is proposing two options: Mazarn 3 Storage Option – Upsize the 793 LF of gravity main from MH 13480 to Mazarn 3 pump station from six-inch to 10-inch diameter. Install approximately 60,000 gallons of storage at the Mazarn 3 pump station to alleviate peak flows during the design storm. Common Force Main Option – Construct a new 12-inch common force main starting near Mazarn 4 pump station, which would manifold into the South Rogers force main. Construct a 10-inch force main from Mazarn 3 and Mazarn 4 pump stations that manifold into the new 12- inch force main. Upgrade the pumps at Mazarn 3 to a capacity of 1-MGD and upgrade the pumps at Mazarn 4 to a capacity of 1.25-MGD. This option also requires upsizing the 793 LF of gravity main from MH 13480 to Mazarn 3 pump station from six-inch to 10-inch diameter. Figure 4.6 on page 4-8 illustrates the proposed routing of flows for this option.
CAPACITY ANALYSIS Page 4-7 Figure 4.4 – Current Routing of Flow Through the Mazarn Tributary Figure 4.5 – Mazarn Tributary SSO Locations
CAPACITY ANALYSIS Page 4-8 The hydraulic model predicts that the storage option at Mazarn 3 would eliminate all SSOs in the Mazarn tributary. This option is advantageous simply on a cost basis and would require operation and maintenance costs throughout its lifetime that are not included in the cost estimate for this option. Construction of the proposed 12-inch common force main would send flows from Mazarn 3, 4, 5, and 6 directly to the South Rogers force main, eliminates all SSOs in the Mazarn tributary, and provides additional capacity for future growth in the area. Additionally, this option would provide energy cost savings by reducing the number of times flow is pumped. Moreover, Mazarn 2 and Mazarn 1 pump stations would no longer be overwhelmed and would require less operation and maintenance costs. Approximately 0.150-MG of additional flow would reach the SWWWTP during the design storm over a five-day period with this option. There are negligible pressure effects at other pump stations connected to the South Rogers force main with the addition of the common force main. The common force main option is being proposed after efforts to maintain the current force main routing while eliminating the four SSOs proved to require upsizing the entire force main downstream of Mazarn 4 pump station as well as pump station upgrades at Mazarn 3, 2, and 1. Figure 4.7 on page 4-9 illustrates the proposed alignment of the 12-inch common force main (highlighted red), which would discharge into the South Rogers force main. Table 4-C on page 4-9 summarizes the cost estimate for both options. The cost estimates for upgraded pumping capacity at Mazarn 3 and 4 includes complete replacement of both stations and the price may be lowered if the existing stations can be altered to accept upgraded pumps.

CAPACITY ANALYSIS Page 4-10 Stokes Pump Station Tributary The Stokes pump station tributary has undergone considerable capacity improvements since the original SECAP report in 2010. This includes the Stokes gravity main interceptor upsizing, Stokes parallel force main, as well as improvements at the pump station. Currently only one SSO is reported to occur in the Stokes pump station tributary at MH 39025. Seven SSOs have been recorded at this location from 2020 to 2021. The hydraulic model does not replicate the overflow at MH 39025 during the design storm event. During the storm event on April 24, 2021 approximately 2-MGD of unidentified inflow was pumped out of the Stokes pump station and monitored at site HS-50. The source of inflow is possibly from a storm sewer cross-connection, or inflow from a nearby creek when creek levels rise during storm events. Additionally, the SSO at MH 39025 is directly upstream of a twin 18-inch section of gravity main located under Mcleod Street and may be experiencing blockage. RJN is recommending that SSES be performed within the Stokes pump station tributary and possibly CCTV the Stokes gravity main interceptor near MH 39025. Figure 4.8 shows the location of the SSO within the Stokes pump station tributary area. Gulpha Tributary The evaluation of alternatives to eliminate the SSOs within the Gulpha tributary are included in the Gulpha Basin Alternative Evaluation Technical Memorandum, which is attached with this report. Figure 4.8 – Stokes Pump Station Tributary SSO Locations
CAPACITY ANALYSIS Page 4-11 Conclusion Several projects recommended in the 2010 SECAP are still necessary to eliminate the remaining wetweather SSO’s in the Hot Springs sanitary sewer system. These include the Lakeside pump station tributary capacity improvements, HSC Interceptor and pump station upgrade, and the Gulpha Interceptor and pump station upgrade projects. I/I abatement studies/projects performed within the HSC tributary may reduce the size of the capacity improvement projects required along the HSC interceptor and HSC pump station. Similarly, I/I abatement studies/projects performed within the Stokes pump station tributary may eliminate the SSO at MH 39025. A summary of all recommended projects, categorized by priority, is shown on Table 4-D below. Budgetary limitations and regulatory requirements were the main drivers of priority recommendations.
