Notification: FAQs

Do you need to notify when laying pipework at depths less than 750 mm or greater than 1350 mm?

Pipework should be laid at a depth of not less than 750 mm (to limit the effect of freezing and mechanical damage) and no greater than 1350 mm deep. They should be embedded in non-abrasive materials. Where this cannot be achieved in all circumstances the consent of the local water undertakers must be obtained via notification.

Where the local water undertaker consents to pipework being laid at less than 750 mm it should be installed as deep as possible below ground level and protected against warming, freezing and mechanical damage (for example due to ground movement).

Pipework should not be installed above ground level is not permitted without the agreement of the local water undertaker.
