Plans for CWWTP Expansion

Metro Water Services is advancing plans for a major expansion of the Central Wastewater Treatment Plant (CWWTP). The plant was originally constructed in 1958 and has been expanded several times through the years to address environmental quality standards and to meet demands of Nashville’s growth.

The CWWTP Capacity Improvements and Combined Sewer Overflow Reduction Project is one of the largest projects in the Clean Water Nashville Overflow Abatement Program. The goal is to make improvements that reduce overflows from both the separate and combined sewer systems to enhance water quality in the Cumberland River and its tributaries.

In addition to improving the operation of the CWWTP, the planned expansion will reduce the overflow frequency and volume from the Kerrigan combined sewer overflow by increasing both the wet weather treatment capacity of the CWWTP as well as the overall capacity of the plant’s Central Pumping Station (CPS). The project will consist of improvements to existing wastewater treatment process units throughout the CWWTP, which will reduce energy consumption, enhance disinfection, and allow for on-site equalization storage.

The CWWTP is located north of downtown, near Germantown and Salemtown, in Council District 19. Design of this large project is ongoing, with initial construction activities beginning in the fall.
