What is water main moling?

Water main moling is a trenchless technique where a pneumatic “mole” drills underground, allowing a new pipe to be installed with minimal surface excavation.

How much does a water main moling installation cost?

Most domestic water main moling projects cost __between £1,200 and £3,000__, depending on ground conditions and pipe length.

When should I replace my water main?

It’s worth replacing if you have lead or galvanised pipes, repeated leaks, or consistently low pressure.

Do I need permission to replace a water main?

You’ll only need approval if connecting to the public main. Private supply pipework within your boundary can usually be replaced without permission.

Can moling be used for all properties?

Moling suits most domestic properties, but very rocky ground or long distances may require traditional trenching instead.
