How do I connect water to my new home?

Connecting water is a key step in the building process. It involves applying to your local water authority or council, engaging a licensed plumber, and ensuring the installation meets national plumbing standards. The process can take several weeks, so early planning is essential, especially in areas where mains water may not be readily available.

Step-by-step: Connecting to mains water

Apply to the local utility or council: Submit an application with your site and building plans to the relevant water authority (e.g. Sydney Water, Tweed Shire Council, Unitywater). They’ll assess your site and provide a connection approval or service diagram showing where the water main is located.

Pay connection and inspection fees: Fees vary based on location, distance to the nearest main, and any required infrastructure upgrades. You may also be charged developer contributions if your build increases demand on the network.

Engage a licensed plumber: Only a qualified and licensed plumber can carry out water connections. They’ll install the water service line, connect to the mains, and ensure compliance with the Plumbing Code of Australia and local standards.

Schedule inspections before backfilling: The water authority or council must inspect the installation before trenches are filled. Inspectors check for correct pipe sizing, depth, materials, and backflow prevention.

Final approval and certification: Once the work passes inspection, the authority issues a compliance certificate. This is required before your Occupation Certificate can be granted.

Rural and off-grid properties

If your site is not connected to mains water, you’ll need an alternative water supply system, such as:

• Rainwater tanks

• Bore water (subject to licensing and testing)

• Carted water (delivered by tanker)

These systems may require separate council approvals, environmental assessments, and ongoing maintenance.

How long does it take?

• Allow up to 6 weeks for approvals, installation, and inspections, or longer in rural or complex sites.

• Delays can occur due to weather, access issues, or utility scheduling.

Bottom line: Water connection is a regulated process that requires council approval, licensed plumbing work, and formal inspections. Whether you're connecting to mains or installing tanks, early coordination helps avoid delays and ensures your home is ready for occupancy.
