Red Bank Sanitary Sewer Improvements
Recent Improvements (Completed Projects)
WWTA Project No. 10-302: Red Bank Sanitary Sewer Rehabilitation (Overflow Abatement at Manhole No. 9181): In 2010, the WWTA, in partnership with the City of Red Bank, applied for and received a Community Development Block Grant for a project to reduce the amount of inflow and infiltration during heavy rain events and increase capacity to minimize Sanitary Sewer Overflows (SSOs) occurring at Manhole No. 9181. The project consisted of two separate contracts. One contract entailed the installation of approximately 2,800 linear feet of 12-inch sanitary sewer pipeline in conjunction with pipe bursting of an existing 8-inch pipeline in Dayton Boulevard, the replacement of 11 manholes, and 10 existing service lateral re-connections. The second contract entailed the installation of approximately 945 linear feet of new gravity sanitary sewer pipeline ranging in size from 10 to 20 inches, approximately 90 linear feet of new 12-inch sewer pipeline by jack and bore, 5 new manholes, and the replacement of 11 existing service laterals in specified areas of Lyndon Avenue, Culver Street, and Dayton Boulevard. The project was completed in April of 2013 and had a total project cost of approximately $991,267.10.
WWTA Project No. 15-306: Red Bank Community Development Block Grant Phase II: The Red Bank Community Development Block Grant sewer project consisted of increasing the size of approximately 2,800 linear feet of sanitary sewer pipeline to address a hydraulic “bottleneck” in the sewer system between Midvale Avenue and Memorial Drive (Red Bank Sewer Basin 02). The goal of this “upsizing” project was to effectively address the hydraulic issues, increase capacity, and reduce inflow & infiltration during heavy rain events in order to minimize Sanitary Sewage Overflows (SSOs). The project was completed in January of 2020 and had a total project cost of approximately $2,310,000.00.
WWTA Project No. 20-329: 2020 Red Bank Selected Sanitary Sewer Rehabilitation: The 2020 Red Bank Selected Sanitary Sewer Rehabilitation project was a “selective” rehabilitation project within Red Bank Sewer Basins 05, 06, and 07 with a goal of reducing the amount of inflow and infiltration during heavy rain events to increase capacity and minimize Sanitary Sewer Overflows (SSOs). The project consisted of the rehabilitation of approximately 1,300 linear feet of 8 inch sanitary sewer pipeline and 22 manholes, 21 service lateral reinstatements with CIPP liners, 64 service lateral connection seals in HDPE lines, and 30 open cut service lateral replacements. The project was completed in December of 2020 and had a total project cost of approximately $950,000.00.
WWTA Project No. 21-338: Red Bank Sewer Basins 05, 06, and 07 Rehabilitation: In 2018, the WWTA conducted flow monitoring and sanitary sewer evaluation surveys (SSES) within the Red Bank service area as a part of the process of identifying priority projects and areas for infiltration and inflow (I/I) reduction to address Sanitary Sewer Overflows (SSOs) for the pending Consent Decree. Upon completion and analysis of the investigations, the WWTA has identified Red Bank Sewer Basins 05, 06, and 07 as priority areas.
Red Bank Basin 5, 6, and 7 represent the highest priority basins in the Red Bank Service Area as they contribute a combined total of 4.45 million gallons of rainfall derived infiltration and inflow from defects in manholes, pipelines, and service laterals. Repairing these assets could result in a substantial reduction in the amount of excess flow entering the system and resulting sanitary sewer overflows in both WWTA’s and the City of Chattanooga’s collection system. Construction is anticipated to begin in early Spring of 2022 with a completion date in the Fall of 2022. Upon completion of construction, the WWTA will conduct additional flow monitoring to determine the effectiveness of the repairs and the capacity within the collection system. The total design and construction cost for the project is projected to be approximately $7,031,535.00.
