Alterations to your property

If you plan to build or do any alteration work on your property, you need to tell us if the work will impact on any SA Water services. You must notify us before work starts. If you are not sure whether it will impact on our services, please contact us.

As a guide, works that could impact SA Water services include:

  • building a new house
  • extending your home
  • building a shed, carport or swimming pool
  • landscaping work.

Your local council may also have approval requirements for alterations.
