What to do if you’re planning works near assets or easements

Review the Guidelines for proposed works over or adjacent to Water Authority Assets, up to and including 225mm diameter (customer build over guide)

These guidelines provide:

  • information on what types of assets we own
  • information on what you can and can’t do near different types of assets
  • information on what steps you may need to take before you can do work near our assets
  • useful diagrams and explanations for renovators, builders or plumbers.

If you’re planning to do any works or building structures over or near any water or sewer assets, you should read these guidelines – they will help you maximise the use of land while using best practice procedures.

Find out the location of nearby assets

By finding out where all the assets near your property are, you can make sure that you won’t damage them while doing works on your property.

You can apply for asset information through Property Connect.

You can also use resources like SEWmap, ASSETWEBMAP and Dial Before You Dig to locate assets.

Get relevant approvals for your works

In accordance with the Water Act 1989, you need our approval if you intend to build over any of our easements or within one metre of water supply, sewerage or recycled water assets. It’s illegal to do works over or within one meter of our assets without permission.

If there is any damage to our assets as a result of your works, you will be responsible for the cost of repairs.

You can lodge a buildover request through Property Connect.
