Goal: Securing urban water supplies 

Faced with continuing dry conditions and uncertainty of future rainfall, alternative water supplies were required in Orange. Continued high-level water restrictions resulted in the community wanting the Council to do something quickly to provide more water for the city. Council wanted a water security solution that would provide long term benefits and considered all elements of the urban water cycle.

Solution: The first large scale, indirect-to-potable stormwater harvesting project in NSW

The Lesson: Drought crisis can lead to testing of new approaches

The Outcomes

1. Cities providing ecosystem services

2. Cities as water supply catchments

3. Cities comprising water sensitive communities
