Managing Prestressed Concrete Cylinder Pipe (PCCP) to Extend Asset Life

This project updated and expanded upon project 4034 by quantifying the impact of condition assessment programs and technology implementation on failure/deterioration rates of prestressed concrete cylinder pipe (PCCP); collecting successful transmission main program approaches as a road map for large diameter, linear asset management programs; and reviewing lessons learned from PCCP management to determine applicability to large diameter pipe constructed with other pipe materials. A methodology was developed to monetize failures to inform a decision-making framework for inspection, monitoring, and rehabilitation efforts. A guidance document was created to enable utility managers to determine best practices for managing their large diameter pressure pipe inventory. Research partner: Great Lakes Water Authority.
