What depth are Underground Utility Services in Australia?

Can utility services be found anywhere at any depth?

Short Answer is YES.

Yes, cables, pipes and other utilities can be found at any depth. There are regulatory standards for depth but in some situations pipes need alternate routes because of obstructions. Later in this post, I will show you the regulatory standards for Australia, and outline what standards should be followed when utilities are installed. There are many factors on why these standards are not always followed or correct, such as weathering grade, obstructions when installed among other reasons. Below are some examples I found personally on the job and other organizations, companies and people that have shared there concerns about this issue.

Some utilities (mostly private residential) are not on dial before you dig maps. To have the best chance of avoiding dangerous utilities, contact your local certified utility locator before any digging, ground penetration or excavations.
