Infrastructure Contributions are one-off charges and are payable when subdividing land to create extra lots that require our services. These contributions help us cover the cost of delivering headworks infrastructure to support the growth in demand resulting from development. This includes infrastructure such as water distribution mains, main drains or pumping stations.

Payment of infrastructure contributions is the land owners responsibility. We will only commit to meeting your water, wastewater and drainage needs once you have paid the relevant contributions.

Standard infrastructure contributions refer to the base level service required by an average residential property in a typical urban location. Other properties with a higher level of service will be assessed in multiples of this amount.

Infrastructure contributions are not subject to GST.

Drainage infrastructure contributions only apply to subdivisions in urban declared drainage areas in the Perth Metropolitan area.

In some areas you may need to pay special developer infrastructure contributions in addition to standard infrastructure contributions.

Are infrastructure contributions payable when I am subdividing?

Infrastructure contributions are payable during subdivision stage when subdividing land to create extra lots.

  • Green title subdivisions - Water supply, wastewater and drainage infrastructure contributions are based on the provision of a base level of service to each new lot.
  • Strata subdivisions - Have the option of being assessed per lot or based on the meter size. Drainage contributions do not apply to strata subdivisions.
