What is a green dome?
You may have seen 'green domes' or pillars in front of homes, in parks or on roadsides. They are like sunken power poles that connect homes to the electricity network.
It is the same electrical wiring that runs from power poles to the top of houses, except underground. The green dome acts as a protective housing for the electrical wires that feed a property.
It’s easy to miss them, as they are coloured green to blend in with natural surrounds, however it is important to remember that they play an important role in supplying your property with power and, if damaged, pose the same risk as a downed powerline.
Take care around green domes
In areas with underground power, homes are connected to the electricity network through service pillars. They’re typically located just inside the property boundary. As pillars contain live electrical wires, they should always be treated with caution.

Know where the underground cables are on your property
In areas with underground power, even though cables are out of sight, it is important to keep in mind they can be very dangerous if accidentally struck or damaged.
It is essential to carefully plan any works in your front yard and proceed with caution where underground electrical assets exist. Not only can it be costly if underground cables are damaged, hitting these cables can cause significant property damage as well as injury or even death.
