Internal plumbing on your property (As constructed)

'As constructed' property plans provide a record of where sewerage drains are located on your property. They do not include information on the size, depth or offset of Western Water's assets, the location of council stormwater pipes or the location of internal water pipes.

You may require a property sewer plan if you are:

  • purchasing a new property
  • having issues with a blocked drain
  • planning to install a swimming pool
  • extending your home
  • landscaping.

If you're planning to change your sewer connection, you'll need to get Western Water's permission. Find out more.
