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.

CWN infrastructure renewal projects on the rise

Shelby Park Rehabilitation and Cowan/Riverside Rehabilitation – began the comprehensive system renewal in vast areas of East and North Nashville. The projects will rehabilitate defective, 1960s-era sewer system pipes and service connections across many square miles of residential and commercial neighborhoods. Improving sewer system performance in these basins will reduce wet weather, sanitary sewer overflows into the Cumberland River.

Annual Rehabilitation FY2013 is a countywide project that will soon start construction to rehabilitate approximately 150 segments of isolated, defective gravity sewer lines and repair service connections. This project spans 28 Metro Council districts with varying levels of rehabilitation work.

In all, Clean Water Nashville this summer is conducting more than 10 major construction projects with more in design and dozens more planned.

Construction of the Shelby Park Rehabilitation will replace aged and defective sewer system pipes that leak during rain events. These first two phases of system infrastructure renewal throughout the Shelby Park project area, which spans East Nashville from Ellington Parkway to Shelby Park, are underway. The first two phases will rehabilitate approximately 108,000 linear feet of gravity sewer, hundreds of manholes and thousands of service connections with primarily trenchless methods. The first two construction phases will be completed in 2015. Design for a third phase will be completed for bid advertisement by fall.

In all, the Shelby Park Rehabilitation project, which includes Council districts 6, 7 and 8, will evaluate up to 585,000 linear feet of gravity sewer system and repair defective infrastructure as needed.

Cowan/Riverside Rehabilitation is in a similarly expansive area spanning from Ellington Parkway into North Nashville along Dickerson Road toward the Cumberland River, across from Metro Center.

Cowan/Riverside, which includes Council districts 2, 5 and 8, will evaluate and repair, as needed, 232,000 linear feet of gravity sewer and hundreds of service connections over several phases in the coming years. The first two construction phases will be completed in 2015.
