Private Works

Private works are any connections, disconnections, or construction work associated with Unitywater infrastructure that requires a quote for works which are to be completed by Unitywater.

This includes:

  • Connection of new subdivisions and other developments to Unitywater’s existing infrastructure;
  • Fire Service connections and large metered water connections (>25mm) for commercial, industrial and residential developments;
  • Modification of existing Unitywater infrastructure to accommodate road works;
  • Development and installation of other services;
  • Minor modification of Unitywater infrastructure (subject to approval) to accommodate property owner requirements (for example raising or lowering of a manhole lid).

To apply for any of these service you will firstly need to obtain approval by lodging an application with Development Services.

After approval for works is received you can submit a water supply and sewerage services private works application (PDF) to obtain a quote.
