Building near Sydney water pipes and other assets

When is approval required?

Sydney Water operates an extensive network of water, sewer and, in some areas, storm water drainage assets. If you are undertaking building work near infrastructure owned by Sydney Water you will need to be aware that:

• approval is required if you intend to build or excavate over or near these assets
• you need prior approval to move, replace or remove Sydney Water’s pipes.

Information regarding the location of Sydney Water assets can be found using the Sydney Water Tap online service. Otherwise, it is recommended you obtain a sewer diagram from an approved information broker.

As much of the Sydney Water infrastructure predates the need for registration of easements on title, it is important to confirm the location of pipes using diagrams provided by Sydney Water or by visiting the Dial Before You Dig website.
