The Sahara® Leak Location system allows pipeline operators to pinpoint leaks in any material with diameters over 100mm (4”). It can be used in live potable water mains with no disruption to customers.
The high sensitivity of the Sahara® System makes it ideally suited to inspecting critical mains. Clients using the system have found it to be so sensitive that they can accept that a “clear run”, with no leaks detected, is the best indication that there are no leaks present. The knowledge that a main is leak free gives a good first indication of the main’s condition. This information helps in planning renovation, renewal and insurance strategies.
Precise location of any leak detected will affect the strategy adopted for its repair. A distance of a few meters – under or alongside a major road or railway line - can make the difference between the need to repair the individual leak or reline or relay the pipeline.
Examples of critical mains include those:
- sited under major roads or railways
- through or under dams and embankments
- in areas of unstable ground
- vital to maintaining supply
