Water main replacement and moling in Londonderry

A water main replacement in Londonderry typically involves isolating the old supply, installing new MDPE pipe, and reconnecting it to the main network.

Many engineers now use moling technology — a trenchless method that allows new pipes to be installed underground with minimal digging.

Moling is ideal if your supply runs beneath driveways, lawns, or patios, reducing reinstatement costs and keeping your property disruption-free.
