The Water Quality Policy was made under section 11 of the
State Policies and Projects Act 1993 and came into effect in September 1997.
The environmental values to be protected under the Water Quality Policy include:
- protection of aquatic ecosystems
- recreational water quality and aesthetics
- raw water for town drinking water supply
- agricultural water uses
- industrial water supply
The Policy also sets sub-values to these broader values.
Water quality objectives may be set for individual surface water and groundwater bodies by first determining which protected environmental values will apply to each body of water.
Provisions of the Water Quality Policy include:
- purpose and objectives
- protected environmental values and water quality objectives
- measures to achieve policy objectives
- management of point sources of pollution
- management of diffuse sources of pollution
