FACT: Leaking pipes account for an estimated 7 billion gallons of water.

Typically, leak-noise correlators have been ineffective when it comes to locating water leaks in large-diameter transmission mains.

Traditional leak detection methods often involve a hydrophone (water microphone) being inserted into a pipe where water carries it downstream as it listens for leaks. However, few utilities conduct leak detection on their transmission mains because of numerous drawbacks of such methods—especially limited accuracy, requiring specialized ports and having to alter water flows.

Fortunately, we are here to help municipal and industrial water service providers with  highly accurate, 100% non-invasive transmission main leak detection that outpaces traditional solutions with service that is: 

  • Easy, fast and cost effective
  • Detects and locates leaks over great distances
  • Does not require specialized ports, closure of service laterals or flow alterations
  • Does not disrupt water service
  • Is not limited by pipe material, size or geometry (90-degree bends, butterfly valves, etc.)

Echologics’ transmission main leak detection service involves two hydrophone sensors that are separately mounted outside of a selected pipe on air valves, fire hydrants or other existing appurtences. Distances between the two sensors can range anywhere from 300ft (100m) to more than 5000ft (1300m). A correlator listens for noise created by leaks that may exist in the span of pipe between the two sensors. The specific location of a leak is determined by the length of time it takes the noise it creates to reach each sensor. Echologics Transmission Main Leak Detection Service can locate leaks within 3ft (1m) of accuracy.

How it Works

This 100% non-invasive leak detection service involves two hydrophone sensors that are separately mounted outside of a selected pipe on air valves, fire hydrants or other existing appurtences. Distances between the two sensors can range anywhere from 1000ft (300m) to more than 5000ft (1300m). A correlator listens for noise created by leaks that may exist in the span of pipe between the two sensors. The specific location of a leak is determined by the length of time it takes the noise it creates to reach each sensor. Echologics Transmission Main Leak Detection Service can locate leaks within 3ft (1m) of accuracy.

To date, Echologics has surveyed over 100 miles (160 km) of transmission mains, locating hundreds of leaks. Bottom Line: if you have a transmission main leak, we’ll find it.
