Hamilton County Water and Wastewater Authority (WWTA) initially entered into a Consent Decree (CD) negotiation with EPA Region IV in October 2014. After 8 plus years of intense negotiations, the final Consent Decree was lodged in October 2023 and went into effect in July 2024. A portion of this CD involved a Remediation Plan to optimize the operability and efficiency of the Signal Mountain wastewater treatment plant (WWTP). The WWTP has past notice of violations due to internal plant inefficiencies; overflows upstream in the collection system and most importantly, bypassing of the biological treatment system during rain events straight to the Tennessee River after disinfection. Like most older systems in the southeast, this plant is subject to significant variations in flow during wet weather events with dry weather flows at approximately 0.3 million gallons per day (MGD), but at > 5 MGD during wet weather events. These drastic variations in flow over short periods of time make operating the plant extremely difficult. To address these upstream challenges from the WWTP, a comprehensive rehabilitation project expected to be under construction soon, however due to the location of the gravity sewers and the extreme topography, significant reduction of infiltration and inflow will require time. To address the immediate bypasses around the biological system there are several planned WWTP improvement projects with this presentation focusing on the addition of an advanced primary filtration allowing the plant to operate during wide flow fluctuations. Pilot Study: Advanced primary filtration and wet weather treatment solutions were explored by conducting a pilot study using cloth media filtration technology. The objective was to evaluate the system's performance in handling influent variations under both dry and wet weather conditions. Pilot Study Findings: •Dry Weather Performance: Achieved average removal of 68% for total suspended solids (TSS) and approximately 52 % for biochemical oxygen demand (BOD5). •Wet Weather Performance: Achieved TSS removal ranging from 66.3% to 84.5%, and BOD removal from 55.2% to 67.6% across multiple wet weather events. Full-Scale System Design: Building on the success of the pilot study, WWTA has moved forward with a full-scale installation to enhance its wet weather treatment capabilities at the plant. Due to topographical limitations at the site, a compact footprint technology was required for the upgrade. The full-scale system is designed to handle a maximum daily flow of 4 MGD with a peak hourly flow of 7.5 MGD. To meet the flow and treatment requirements, two units in concrete basins were selected. The system is designed as a Dual-Use application, with the units operating in different modes based on flow conditions. During dry weather, one filter will handle the primary treatment flow, while the second filter will remain offline. When wet weather events occur, the second filter will be activated, enabling the system to manage the increased flow. Upon completion in 2026, this innovative solution will enhance treatment efficiency and play a crucial role in safeguarding public health by mitigating the impacts of sewer overflows and improving overall system resilience.
