Mayor Barry visits sewer rehabilitation project

Mayor 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.

“Updating our wastewater infrastructure system is a smart investment in Nashville’s future,” said Mayor Barry. “The ongoing improvements we make will improve water quality in the Cumberland River and Davidson County’s extensive network of neighborhood creeks, streams, and tributaries.”

Construction on the 28th Avenue Rehabilitation – Area 1 – Clifton Avenue project, located in Metro Council District 24, began in April 2016 and is scheduled for completion in May 2017. For this project, crews are rehabilitating approximately 39,600 linear feet of gravity sewer, associated manholes, and services laterals within Metro’s rights-of-way and easements.
