Corrosion of prestressing wire in Prestressed Concrete Cylinder Pipe (PCCP) and other structures is a widespread concern for owners and managers responsible for these facilities. The general inaccessibility of the pipe and prestressing wire makes evaluation difficult, costly and often inconclusive. Random examination of prestressing wires by excavation or internal inspection of the pipe wall gives only a very localized knowledge of the prestressing wire condition. The operation of a recently developed acoustic system for monitoring PCCP to determine the time and location of pipe deterioration is discussed. A case study detailing the experience of the Arizona Public Service Company (APS) who manage a prestressed effluent line providing cooling water as operating agent of the Palo Verde Nuclear Generating Station is presented.
