Alternative water

By using a non potable water supply as an 'alternative water source', where appropriate, it is possible to significantly reduce the amount of potable water used by your development.

Different types of alternative water require varying levels of treatment and the uses permitted for an alternative water source will vary depending on the type and the treatment method selected.

Alternative water sources recognised in BASIX include; rainwater, stormwater, grey water, recycled effluent, and for single dwelling developments only, private dams.

Acceptable uses can include:

  • garden and lawn
  • toilets– only if all toilets are connected
  • laundry
  • hot water– only if all hot water uses the alternative water source
  • household uses– only if all water uses the alternative water source
  • pool and spa top-up
  • cooling tower make-up water
