This considers reduction in potable water use through water efficiency mechanisms and source substitution, as well as end user education initiatives.
Improve water use efficiency.
Measures that would achieve at least a 20 per cent reduction in potable water use beyond regulatory measures and have no potable water irrigation requirements.
Reduce potable water use. There are two fundamental strategies to achieve this:
- Reduce overall water use by 20 per cent beyond regulatory means - e.g. through water efficiency mechanisms.
- Utilise alternative water sources (e.g. rainwater, stormwater, dual reticulation) to meet irrigation demand for public open space and common areas of the project or use drought tolerant species which require no establishment period.
