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

Date added: 25-Jul-2016 07:34 AM

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.

Compact encourages new engineering for old designs

LONG-TERM QUALITY AND CONSERVATION of Nashville’s waterways demands enhanced stormwater practices and deeper public understanding and awareness. Fortunately in Nashville, numerous organizations are contributing to the conversation and creating momentum.

The Cumberland River Compact recently hosted a high-profile speaker series entitled Innovations and Solutions that focused on the most pressing environmental, legal, and political issues facing our local waterways. The series highlighted policies, regulations, and projects that will improve water quality and stream health.

Rebecca Dohn, Metro Water Services, previewed the upcoming 2016 policy changes that will require all new development projects to capture the first inch of rainfall on their sites. Benefits and incentives for this path are listed on the MWS website.

“This design methodology attempts to mimic a site’s natural hydrology, which helps mitigate the impact of development on our waterways,” said Dohn.

Civil & Environmental Consultants’ Steve Casey, discussed a recent stormwater upgrade project to improve the water quality of Cathy Jo Branch, a small headwater stream flowing through the Nashville Zoo. The project, conducted in collaboration with the Zoo and the Cumberland River Compact, has improved water quality for the stream, removed six acres of invasive plants, and created a new exhibit space of native grass prairie for elk and bison.

Through collaboration, education and action, the Compact’s goal is to ensure clean and abundant water sources that support life, recreation and economic well-being for generations to come. To learn more about the Cumberland River Compact, visit http://cumberlandrivercompact.org/.
