Description
San Francisco Public Utilities Commission (SFPUC), a large water purveyor serving 2.4million of wholesale and retail customers, has installed 32 miles of prestressed concrete cylinder pipe (PCCP) since 1967.To help manage its PCCPs proactively, SFPUC has selected and worked with OliviaChen Consultants (OCC) to develop a Prestressed Concrete Cylinder Pipes ReliabilityEnhancement Program (PCCP REP). The implementation of this program would preventcatastrophic failures and extend the service life of these pipelines.The project involved evaluation of the existing condition, potential hazards, andcriticality of the installed PCCP. It also included a study of the causes of PCCP failureand failure modes, case history evaluation of other utilities’ PCCP failures, and review ofthe state of the art monitoring and repair technologies for the PCCP. In addition, OCChas developed a method to establish priorities for monitoring its PCCP and a decision-makinglogic diagram to assist SFPUC in developing the most cost-effective PCCPmaintenance program. This program can also be used by other large utilities in theireffort to monitor and maintain their PCCP cost-effectively with limited funding and staffresources. Includes abstract only.
