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

Dial Before You Dig is a community service organisation supported by Ausgrid and other major service providers. It can provide plans of where electricity, water, gas and telecommunications cables and pipes are located so you know whether it is safe to dig.

NSW legislation now requires people who are planning to do excavation work to obtain copies of underground electricity cable plans through Dial Before you Dig (Phone - 1100) and to make sure that the plans are no more than 30 days old when excavation commences.

The aim of the legislation is to ensure that when workers dig near electricity cables, they will establish the exact location of the cables and thus avoid coming into contact with them or damaging them.  This will ensure worker safety and also prevent disruption to Ausgrid's electricity network.

Ausgrid Network Standard NS 156 Working Near or Around Underground Cables, contains comprehensive information concerning all the issues that arise when excavating near underground cables (such as safety hazards from asbestos conduits and organochlorine pesticides).You must consult the Standard, and comply with the requirements in this Standard if you are excavating near our electricity mains. Our summary brochure Working near Ausgrid cables will give you a brief overview of how to prepare for excavation works near or around electricity cables. 

It is important that you also consult our guide Reading Ausgrid plans and make sure that workers engaged in excavation works fully understand how to read the plan.   If the people actually doing the digging can't read the plans, it is essential that the work is directed by a person who has been trained to read Ausgrid's plans. You must also keep plans on site during excavation works.

In addition, WorkCover NSW has developed a Guideline Work near underground assets: Guide to assist you in deciding appropriate measures to eliminate or control risks when working near underground assets.

Your Dial Before You Dig plans should arrive or be ready for collection within three working days. Please read the slip and check the details. If you are unsure of, or if you have experienced a delay in receiving your plans, please call us on 13 15 25 before starting any digging or excavation work.
