Saving water
Dual water system
The water system at Sydney Olympic Park supplies drinkable water from the mains water supply through one set of pipes, and recycled water for toilet flushing and watering plants through a second system of pipes.
Sewage is treated in on-site waste water cleaning and treatment plants before being reused for irrigation and toilet flushing. Storm water run off is caught in channels designed to imitate the natural water cycles of creeks and wetlands, stored on-site, then treated in the water treatment plant before use.
Water-efficient appliances
Olympic venues conserve water through efficient appliances, including water-flow saving showers, dual flush toilets, rainwater tanks and drip irrigation systems.
Native trees
Australian native trees and shrubs have been planted around venues to reduce water and mulching needs.
