Working safe

Dial Before You Dig

Ausgrid has a large network of underground cables. For safety reasons, it is extremely important that you check for electrical cables and other utility cables (including gas, water and sewerage) before you start to dig or excavate.

Ausgrid pit - Asset relocations

Dial Before You Dig is a FREE national referral service supported by Ausgrid and other major service providers that supplies plans of where electricity, water, gas and telecommunications cables and pipes are located so you know whether it is safe to dig.

NSW legislation requires people who are planning excavation work to obtain copies of underground electricity cable plans from Dial Before You Dig. The plans must be no more than 30 days old when excavation commences.

The aim of the legislation is to ensure workers can establish the exact location of cables and avoid coming into contact with them or damaging them. It also ensures worker safety and prevents disruption to Ausgrid's electricity network.
