Subsurface Locating · Acoustic & electronic diagnostics

Water main leak detection

A buried main losing water often announces itself first on the bill. Acoustic and electronic diagnostics narrow the leak to a documented indication zone from the surface, so the dig starts small and starts in the right place. Hundreds of miles of mains tested.

Who calls, and why

Owners and homeowners

The buried line from the street shut-off to the building is the owner's to fix, residential included. The leak gets found before the lawn, the driveway, or the water bill pays for the guesswork.

Commercial and institutional

Condo associations, golf courses, malls, hotels, hospitals, campuses, airports: anywhere a main run is long, buried, and expensive to dig on a hunch. Plumbing contractors bring us in for exactly that reason.

Industrial and municipal

Plants, distribution centers, military bases, water treatment facilities, schools and public works: large systems where unaccounted water is a budget line and an infrastructure risk.

Not sure where the lines even run? That is utility locating; water lines are the hardest to trace, and locating them is practiced work here. The whole family lives at subsurface locating.

FAQ

Water main questions

How do you find a leak in a buried water main?

Acoustic and electronic diagnostics, from the surface. A pressurized leak makes noise and disturbs its surroundings in ways instruments can read; working along the run, the technician narrows the leak to a documented indication zone. Nothing is excavated to find it; the excavation happens once, where the evidence points.

How do I know I have a water main leak at all?

The classic signs: a water bill that climbed and stayed up, unexplained wet or green patches along the run, low pressure, or a meter that spins with every fixture off. A buried main can lose water for months before anything shows at the surface. The bill usually knows first.

I am a homeowner. Do you handle residential water mains?

Yes. The buried line from the public shut-off at the street to your house is yours to maintain, and finding a leak in it is exactly this service. What we are not is a plumbing leak service: leaks in the plumbing inside the house are a plumber’s call.

What do I get at the end?

Leak indication zones marked and documented, field notes, and a written report of findings and limitations. We perform no repairs. The report is what your contractor digs from, and the indication zone sits where the readings put it because we are not the ones digging.
