SADM17 - Water Supply and Waste Water

Development proposals must take into account the demand for off-site water service infrastructure.

In particular, developers will be required to demonstrate that there is adequate waste water capacity on and off the site to satisfactorily serve the development.

Development proposals will be permitted where:

  • sufficient infrastructure capacity already exists; or
  • extra capacity can be provided in time to serve the development.

Water efficiency measures should be incorporated into the development. For residential development, efficiency measures should enable a maximum potable water usage of 110 litres per person per day to be achieved. The design of non-residential building development should enable achievement of the BREEAM ‘Excellent’ standard or the best practice level of the Association for Environment Conscious Building Water Standards or equivalent.
