Electro Scan UK Ltd, in collaboration with Clancy and Southern Water, used its patented Focused Electrode Leak Location (FELL) technology to deliver post-CIPP quality assurance across multiple wastewater sites. Traditional CCTV inspections often failed to detect defects behind liners or at joints. Electro Scan’s ES-400 system automatically identified and quantified defects in litres per second, revealing undetected leaks and verifying rehabilitation effectiveness. The project provided Southern Water with objective, repeatable data to validate lining performance, reduce infiltration risk, and support AMP7/8 outcomes—marking a step-change in QA/QC standards for sewer rehabilitation.
