Mayor Barry visits sewer rehabilitation projectMayor Megan Barry recently visited Clean Water Nashville’s 28th Avenue Rehabilitation – Area 1 project site to learn more about how Nashville’s aging sewer infrastructure is being renewed. As pictured, B.J. Kersteins of Insituform Technologies, Inc. (the construction contractor for this work) shows Mayor Barry a cured-in-place pipe liner. The pipe liner is inserted in the sewer to renew the system without excavating streets. Repairing sewers in this way extends the life of the system and addresses downstream overflows by reducing the amount of rainwater that infiltrates the system.

CWWTP: Gathering neighborhood input

On January 15, 2018, Metro Water Services (MWS) participated in a meeting with residents from the redeveloping neighborhoods of Salemtown and Germantown to discuss the improvements to the nearby Central Wastewater Treatment Plant (CWWTP).

In particular, MWS sought input on the architecture for a new headworks building currently under design which will be located along 3rd Avenue North. Several options were provided for discussion. Also, MWS requested feedback from residents on potential uses for a future green space along 3rd Avenue North from Coffee Street to the Magdeburg Greenway near Morgan Park. As part of the CWWTP improvements, MWS is considering options for landscaping improvements along this corridor to enhance the interface with the Germantown and Salemtown neighborhoods. Potential options may include a pocket park, community garden, or trees and plantings.

MWS continues to advance the design for a major expansion of the CWWTP. The plant, which serves the majority of Nashville, 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 the largest project in the Clean Water Nashville Overflow Abatement Program. 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 Central Pumping Station. The project consists 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 2020.
