Buried pipe leaks
Drinking-water mains, private and shared networks
Public and private water networks
Leak location on buried water pipes and technical installations.
Common problems
Chambers and valve pits
Leaks on valves, fittings and equipment
Excess water consumption
Detecting and locating invisible leaks
Irrigation networks
Watering of green spaces, golf courses and private networks
Reservoirs and pumping stations
Inspection of structures and related networks
Our technologies
On buried networks we work in two steps: pre-locating the area, then pinpointing the leak.
Acoustic correlation
Pre-locates the leak between two valves or access points.
Electro-acoustic listening
Pinpoints the leak from the surface.
Tracer gas
Essential on plastic pipes and at low pressure.
Pressure testing
Sectorises the network and quantifies losses.
Electromagnetic locating
Locates the route and depth of metal pipes.
Ground-penetrating radar
Detects non-metallic pipes and voids.
Network mapping
Surveys and georeferences networks for your plans.
Pipe video inspection
Inspects the inside of pipes and chambers.
Our interventions
A few real cases handled by our teams, taken from our intervention reports.
GolfGolf course
A loss of about 10 m³ per day persisted even with the irrigation valves closed. Acoustic listening and tracer gas located a buried leak on the main supply network, in front of a fire hydrant.
PoolHouse with pool
The pool's return line had already leaked twice before. Tracer gas located a new buried leak in the garden, opposite the ladder, without breaking the ground.
