2011 Collection System Structural Defect Repair project completed

The 2011 Collection System Structural Defect Repair project involved repair of wastewater infrastructure across an expansive area of the Whites Creek and Richland Creek drainage basins in northwest and west Nashville. The project is the largest so far from a geographic standpoint, spreading across 10 Metro Council districts.

Work included repair to cracked and broken system pipes that had begun to leak and diminish system capacity. The program’s contractors used closed circuit television cameras, extended by cables into the pipe system, to identify deterioration and catalog more than 25 major repairs.


Construction crews used two primary methods to make repairs to underground pipes. One, known as cured in place pipe, involved inserting a flexible resin saturated liner into a manhole and along the length of the pipe. The liner forms to the circular shape of the pipe, and then workers introduce steam or hot water that hardens the epoxy resin and forms a new plastic liner within the original host pipe for a secure, permanent repair. The second method involved excavating six- to- eight-foot sections of broken pipe for installation of replacement pipe that is coupled into the existing system.

All roadway, public easements and residential properties that were disturbed for repairs were promptly returned to pre-existing condition.
