Cumberland River Compact driving water quality awareness and educationEnvironmental awareness and education is vitally important to the health of the Cumberland River and area creeks and streams. Nashville is fortunate to have community partners such as the Cumberland River Compact dedicated to improving the watershed.

The Cumberland River Compact, a group of citizens and community leaders, created the Cumberland River Center to lead protection of the river against pollution, drought, storm water runoff and other challenges.

2011 Collection System Structural Defect Repair project completed

Date added: 11-Aug-2015 09:26 AM

2011 Collection System Structural Defect Repair project completedThe 2011 Collection System Structural Defect Repair project involved repair of wastewater infrastructure across an expansive area of the Whites Creek and Richland Creek drainage basins in northwest and west Nashville. The project is the largest so far from a geographic standpoint, spreading across 10 Metro Council districts.

Work included repair to cracked and broken system pipes that had begun to leak and diminish system capacity. The program’s contractors used closed circuit television cameras, extended by cables into the pipe system, to identify deterioration and catalog more than 25 major repairs.

Conveyance Improvements Underway

The Brick Church Pike Pipe Improvements project illustrates the sometimes demanding challenges that are encountered as Clean Water Nashville Overflow Abatement Program (CWNOAP) renews and enlarges Davidson County’s sewer system.

The purpose of the Brick Church Pike Pipe Improvements project, located in Metro Council District 3, is to increase capacity in the sewer system and therefore reduce surcharging and sanitary sewer overflows caused by excessive rainwater entering the sewer system. Sanitary sewer overflows, or SSOs, are discharges of untreated sewage to the environment including public or private property.

Comprehensive, coordinated planning has been conducted to minimize construction impacts to local residents, businesses, and the environment while maintaining a safe work environment for all involved. Clean Water Nashville follows all local, state, and federal environmental policies in order to minimize disturbances to natural waterways, to conduct maintenance of riparian zones, and to protect natural habitat.

The construction work planned for Brick Church Pike Pipe Improvements includes:

  • Excavation, primarily through trenching, for installation of 9,400 linear feet of large diameter (24-inch to 30-inch diameter) gravity sewer pipe, 500 linear feet of small diameter sewer pipe, and associated manholes. This excavation and installation work will primarily occur in grassy areas outside of roadways.

  • Trenchless crossings of Briley Parkway, Brick Church Pike, and the North Fork of Ewing Creek with excavated bore pits on both sides of the crossing

  • Sewer rehabilitation, where needed, using slip lining methods

  • Careful work in and around the North Fork of Ewing Creek to install new sewer pipe while following applicable environmental policies for protection of creeks, streams, and preservation buffers

In addition to the Brick Church Pike Pipe Improvements project, two additional, interconnected projects have been identified by Clean Water Nashville in order to address sewer system limitations in the North Fork of Ewing Creek-area. These projects are the following:

  • Westchester Drive Rehabilitation: This neighboring project, completed in 2015, involved rehabilitating approximately 3,850 linear feet of 10- and 18-inch sewer pipe along and crossing the North Fork of Ewing Creek, a tributary to Whites Creek. The rehabilitation work is expected to renew the system infrastructure and address leaky pipes in the existing system. The Westchester Rehabilitation project area is immediately upstream of the Brick Church Pike Pipe Improvements project.

  • Ewing Creek/Brick Church Equalization Facility: During large rainfall events, the excess flow conveyed through the Brick Church Pike Pipe Improvements project will be temporarily stored in the Ewing Creek / Brick Church Equalization Facility. When constructed, that facility will consist of a 10.6 million gallon storage tank and an 18 million gallons per day wet weather pumping station. The new facility in conjunction with other projects will provide the necessary capacity to address sanitary sewer overflows in the area. The project is scheduled to start construction in 2017.
