Cured-in-place pipe lining seals the deal

Date added: 24-Aug-2016 09:19 AM

Cured-in-place pipe lining seals the dealCured-in-place pipe (CIPP) lining is one of several sewer rehabilitation methods used to repair leaking or structurally unsound existing pipelines. Little to no digging is involved in this trenchless process, making for a more cost-effective, environmentally friendly process that is completed more quickly and with fewer impacts and disruptions than pipe replacement.

Mayor Barry visits sewer rehabilitation project

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.

East Nashville rehab projects continue in Inglewood and Jackson Park neighborhoods

COMPREHENSIVE SEWER SYSTEM RENEWAL throughout large areas of East Nashville and Inglewood continues with the start of the Shelby Park Rehabilitation—Area 4—Brush Hill Road project.

This large scale project will repair sewer infrastructure in an area on the east side of Gallatin Road within the boundaries of Brush Hill Road, Riverwood Drive, Log Cabin Road, and Freemont Avenue. The project is in the Inglewood and Jackson Park neighborhoods in Metro Council District 7.

Following the assessment of more than 47,000 linear feet of existing sewers, the resulting construction project will rehabilitate approximately 38,000 linear feet of existing sewer pipe that is sized between 8 and 18-inches in diameter. Work will also include renewals of service laterals and manhole rehabilitation. About 60 percent of the work will be conducted in roadways and the remainder in easements on residential properties. To the extent possible, the work will rely on construction practices that minimize surface disturbances in the area.
The repairs are required to update defective 1960s-era sewer system pipes and services connections. The Shelby Park Rehabilitation—Area 4—Brush Hill Road project continues extensive rehabilitation of older sewers in Nashville. Improving sewer system performance in these areas will reduce wet-weather, sanitary sewer overflows into Nashville’s waterbodies.

Construction began in July and is anticipated to be completed in summer 2016.
