Leak Detection & Locating

Leak detection and locating systems identify and pinpoint the precise location of fluid or gas losses from underground pipelines, pressurized vessels, building plumbing systems, and industrial process infrastructure — reducing water loss, preventing environmental contamination, and avoiding structural damage caused by undetected leaks over time.

Acoustic leak detection is the most widely deployed method for underground pipe surveys. Leak noise correlators place sensors on two accessible fittings — hydrants, valves, or standpipes — on either side of a suspected leak zone. Each sensor picks up the acoustic noise generated by fluid escaping under pressure through a pipe defect. The correlator calculates the precise leak location by measuring the time difference between arrival of the leak noise at each sensor and applying pipe material, diameter, and distance parameters entered by the operator.

Tracer gas leak detection injects a hydrogen-nitrogen mixture or helium into a pressurized pipe section. These gases diffuse through pipe defects and soil, rising to the surface where a handheld detector measures tracer gas concentration. This method locates leaks on non-metallic pipes including HDPE, PVC, and asbestos cement mains where acoustic methods produce weak signals.

These systems serve Pakistan’s WASA water distribution networks in Lahore, Karachi, Faisalabad, and Multan, SSGC and SNGPL gas distribution operators, oil and gas pipeline contractors in Sindh and Balochistan, and building services contractors across Pakistan’s major cities requiring non-destructive underground leak location before excavation.
