Water Main & Underground Supply Pipe Repair

Find specialist companies that investigate and repair underground water mains and water supply pipes. A successful repair starts with identifying the affected pipe, locating the defect and agreeing who is responsible for the work.

What Does Water Pipe Repair Involve?

The engineer establishes the pipe route and material, investigates the suspected leak and explains the proposed access. A local repair may involve exposing a short section, fitting a suitable repair or replacing a damaged length, then checking the connection before reinstating the surface.

A pipe described as a water main may be part of the public network or a private commercial system. Confirm ownership with the relevant water company before instructing work on a public asset. Read our guide to mains, individual and shared supply pipes.

Repair or Replace?

A local repair can suit an isolated defect in otherwise serviceable pipework. Repeated leaks, deteriorated pipe material or an awkward route may make water supply pipe replacement more practical. Ask the contractor to explain the evidence for its recommendation, including the remaining condition of the existing pipe.

What Should a Repair Quote Include?

• The investigation included and how the leak position will be established.
• The pipe section, jointing method and any assumptions about buried services.
• Excavation, access, waste removal and the agreed standard of reinstatement.
• Supply isolation, checks on completion and any applicable certification.
• How unexpected ground conditions or additional defects will be quoted.

Where the leak has not been located, compare acoustic and tracer-gas leak detection capability before choosing a repair team.
