Standards For Testing And Certifying Cured-In-Place Pipe

It is estimated that nearly 75,000 miles of wastewater and water pipelines have been lined with Cured-In-Place Pipe (CIPP), with nearly $3 billion spent annually on the trenchless renovation method, worldwide. Recognizing the growing use of CIPP and inability of CCTV inspection to accurately or consistently certify trenchless rehabilitation as defect-free, this paper chronicles the emergence of new guidelines to test, certify, and accept CIPP lining projects, using Focused Electrode Leak Location (FELL) inspection.
