Repairs to Unlined RCP, Reach IV-A Outside of Prado Inundation Pool

Value: $2,244,775.00 Contractor: Insituform Designer: RBF Consulting Schedule: July 2011 – May 2011

This project include about three miles of the Brine Line (Reach IVA Upper) outside of the Prado Dam inundation area. This portion of the Brine line was installed in the 1980’s and was constructed of unlined reinforced concrete pipe (RCP). Core samples and a subsequent condition assessment report concluded deterioration of the concrete within the pipe. It was recommended to rehabilitate this portion of the Brine Line with the Cured in Place Pipe (CIPP) method. The Project as designed will eliminate the effect of the on-going structural deterioration of the unlined RCP and reduce the risk of a catastrophic failure. The project will extend the useful life of this portion of the Brine Line an additional 50 years.
