Water Research Foundation, CFRP Renewal of Prestressed Concrete Cylinder Pipe, Project 4352

United States


Water Research Foundation



Prestressed-concrete cylinder pipe (PCCP) makes up a significant portion of pipelines for the world's water, wastewater, and cooling water systems. Distress to PCCP can include broken wires, cracked core, or corroded steel cylinder. Renewal of distressed PCCP may be accomplished by lining the pipe with carbon fiber-reinforced polymer (CFRP), which eliminates the need for excavation and minimizes service disruption. Under contract with the Water Research Foundation, SGH conducted the research that formed the technical basis of the American Water Works Association (AWWA) standard in this area.
