Leak tightness testing
Proven confidence for CIPP Systems
Following a collaborative project led by WRc with six UK water companies, the Government of Jersey and eight CIPP suppliers, WIS 4-34-07 Specification for Leak Tightness Testing of CIPP Lining Systems has now been published.
This specification gives the water industry a consistent, reliable way to assess leak tightness and identify products that help reduce groundwater infiltration into already stretched sewer networks. With growing regulatory pressure and AMP8 investment focused on cutting sewer spills and improving network resilience, independent performance testing is increasingly essential.
Leak tightness testing for CIPP systems, end seals and connection collars
As a key contributor to the development of the method, WRc now offers leak tightness testing for CIPP systems, end seals and connection collars in accordance with WIS 4-34-07, giving manufacturers verified performance data and helping clients specify solutions with confidence.
