Cured-in-place pipe lining seals the deal

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.

Clean Water Nashville OAP begins project work

The Clean Water Nashville Overflow Abatement Program initiated construction on the following major projects in the second quarter of 2012:

  • Expansion of storage capacity at the MWS Driftwood CSO Equalization Facility on Driftwood Street. The facility will be expanded to provide an additional 3 million gallons of storage at the site to reduce combined sewer overflowscombined sewer system conveys both sanitary sewage and stormwater in one piping system. During normal dry weather conditions, sanitary wastewater collected in the combined sewer system is diverted to the wastewater treatment plant before it enters natural waterways. During periods of significant rainfall, the capacity of a combined sewer may be exceeded. When this occurs, excess flow, a mixture of stormwater and sanitary wastewater, is discharged at CSO points, typically to rivers and streams. Release of this excess flow is necessary to prevent flooding in homes, basements, businesses, and streets. into the Cumberland River. The project began in June and will be completed in the first quarter of 2013.
  • Expansion and other improvements to the Dodson Chapel Pumping Station and Equalization Facility, located on MWS property on Panama Drive, including construction of a new storage tank and dry weather pump station, and modification of existing equipment.
