Our Water Line Leak Detection Capabilities

Our leak detection services can help you find and pinpoint the location of hidden leaks in underground water lines on both commercial and residential properties. By using a customized seven-step leak detection process and a combination of acoustic ground microphoneacoustic correlating logger, and Helium gas detection technology, we are capable of finding leaks in the following types of water lines and pipe materials.

Water Line Types: 

  • Municipal Water Mains
  • Municipal Water Laterals
  • Commercial Water Mains
  • Commercial Water Service Laterals
  • Residential Water Service Laterals
  • Heating Lines
  • Cooling Lines
  • Steam Lines


Water Distribution System on a Commerical Property

Pipe Material Types: 

  • Ductile Iron
  • Copper
  • Steel
  • PVC (Polyvinyl chloride)
  • LDPE (Low-Density Polyethylene)
  • MDPE (Medium-Density Polyethylene)
  • HDPE (High-Density Polyethylene)

Nine Common Signs of an Underground Water Leak

Before deciding whether or not a leak detection survey is needed, it is first necessary to look for one or more of the following signs to determine if a leak is actually present:

Wet Spots and/or Pooling Drop in Water Pressure Brown or Dead Spots
Pool of Water in a Grassy Area

Wet spots in landscaped areas and/or water pooling on the ground surface.
Water Line With Zero Pressure

A noticeable drop in water pressure or flow volume. Or, unexplained sudden increase in water use, consistently high water use, or water use that has been climbing at a fairly steady rate for several billing cycles.
Irrigated Lawn No Longer Receiving Sufficient Water

A portion of an irrigated area is suddenly brown, dead, or dying, when it used to be thriving (water pressure is too low to enable distant heads to pop up properly).

Cracking Asphalt Potholes Green, Moldy, or Soft Area
Cracking Asphalt Surface

Heaving or cracking of asphalt surfaces. 
Large Pothole Filled With Water

Potholes on asphalt surfaces.
Large Patch of Green Grass Surrounded by Drier Grass

An area that is green, moldy, soft, or mossy surrounded by drier conditions.


Sinkholes Dirty Water High Water Use & Bills
Large Sinkhole on an Asphalt Surface

Large Sinkholes on asphalt, grass, or other types of surfaces.
Faucet With Rusty Water Flowing Out of It

A sudden problem with rusty water, or dirt or air in the water supply (there are other causes for this besides a leak).
Extremely High Water Bill

Unexplained sudden increase in water use, consistently high water use, or water use that has been climbing at a fairly steady rate for several billing cycles.


Our Two Leak Detection Survey Design Options

Once it has been confirmed that a leak is present, we offer our clients two different survey design options. Feel free to choose the option that best fits your needs. If you are not sure which one that is, we can recommend one for you after learning more about your project.

Single Line
Single Line Leak Detection Survey

In residential water and commercial water systems suspected of having just one leak, the acoustic ground microphone, acoustic correlator, or helium detection technology can be used to search for a leak one line at a time.




Multiple Lines
Multiple Line Leak Detection Survey

In commercial domestic or fire water protection systems that are suspected of having multiple leaks, the acoustic correlating technology can be used to check multiple lines or sections of a line in one single reading.
