Safety With Underground Cables

Check Before You Dig

The positions where cables are buried are subject to reasonable tolerance however, the depth of cover may have changed since installation. It is your responsibility to verify the position and depth of cables before excavation. If cables are not in the position shown on the plan or you require help, call MainPower (03) 311 8300 for further assistance.

Serious personal injury can result from damaging underground services during excavation and ground penetration, such as posthole drilling. Supply disruption and repairs can be costly and extremely irritating to customers.
