Sydney Water is wholly owned by the New South Wales government and manages an area of 12,870km2, including the management and operation of 22,342 km of drinking water mains and 26,169 km of sewer mains.
Electro Scan’s Focused Electrode Leak Location (FELL) technology was used to evaluate these sewer mains ranging from 150 mm to 400 mm (6–16 inch) diameters, including clay, cured-in-place lined pipe (CIPP), earthenware, plastic and Rib-Loc spiral wound lined pipes.
Traditionally, water utilities rely on high resolution cameras and visual inspection to manually access defects or use pressure tests on existing and new pipe installations which may falsely measure water tightness.
Sydney Water Senior Engineer Jerry Sunarho was responsible for coordinating the project trial using the new technology that would mitigate these risks.
“We will use the findings from this trial to see if we can improve the way we test our new and rehabilitated pipelines and prioritise our repair strategies for existing wastewater pipelines,” said Mr Sunarho.
Electro Scan CEO and Founder Chuck Hansen said the company was delighted to be invited to Australia to demonstrate the features and benefits of its patented low voltage conductivity.
Data from the project trial was automatically processed in the field with results accessible in minutes on Electro Scan’s cloud-based Critical Sewers® application.
All work for Sydney Water was completed in accordance with ASTM F2550-13 (2018).
