The Crest Sustainable Stormwater Management Project aims to reduce our reliance on mains water and increase the quality of our environment. The project relies on rainwater collected from the velodrome roof and stormwater from a small urban area, to water the surrounding playing fields of The Crest Complex. It ​will save 20 million litres of drinking water each year and ensure that playing fields can be watered even in tough drought conditions. 

The project will: 

• Supply more than 80 per cent of irrigation demands by increasing the capacity of the existing pond;
• Improve stormwater quality in the Prospect Creek catchment by creating a bio retention system (raingarden) that will capture and remove pollutants from the water;
• Improve aesthetics and increase biodiversity in the area through landscaping, removing weeds and enhancing native vegetation which will encourage native animals;
• Help mitigate floods downstream by capturing and storing stormwater during large rain events for later release;
• Treat all water used for irrigating playing fields in accordance with guidelines for water recycling; and 
• Reduce its construction ecological footprint by using as many eco-friendly products as possible.
