SG3 Contract C Small Diameter Rehabilitation

complete / construction

The Department is continuing the implementation of the Sewer Rehabilitation Program to upgrade its existing small diameter sewers to reduce the amount of extraneous flows, infiltration and inflow (I/I) entering the system, in addition to eliminating sanitary sewer overflows and capacity limitations. To accomplish this objective, the City is proposing system improvements for small diameter sewers situated in both the Camp Creek and Utoy Creek Sewer Basins and will be located in approximately eleven sewer sheds. This project is necessary to meet the requirements of the Second Amended Consent Decree (SACD), which prescribes evaluation and improvement measures to eliminate sanitary sewer overflows (SSOs) and to protect the City’s investment in upgraded water reclamation facilities. Structural upgrades to the system are necessary to replace old and deteriorated sewers in order ensure the extended service life, reliability, and improve flow conveyance. The current milestone completion date for the work under this project is July 1, 2020. The scope of this project includes: Pre-cleaning sewers, Lining of sewers using Cured-in-Place pipe (CIPP) liner, Replacing sewers through pipe bursting, Installing new sewer sections using horizontal directional drilling methods, Replacing sewer through open-cut method, Addressing defects in short pipe sections through internal and external point repairs, Rehabilitating manholes
