South Australia’s unique climate and geography brings relatively low rainfall and drought that could put water supplies at risk, and the State is recognised internationally for its capabilities in water resource management and its networked water distribution system.
The State has moved to diversify water supply sources over a number of years, having invested in recycled wastewater, stormwater reuse and desalinated water to provide climate-independent sources of water to supplement water from its reservoirs, the River Murray and groundwater.
The Water Industry Act 2012 provides that the government maintain strategies to ensure the State's water supplies are secure and reliable and are able to sustain economic growth.
More than 50 per cent of Adelaide’s annual demand can be met with recycled or desalinated water.
SA Water maintains and operates 32 reservoirs and weirs across the state including 10 major metropolitan reservoirs, and maintains one of the largest supply networks in the southern hemisphere with more than 27,000 kilometres of water mains and more than 8,900 kilometres of sewerage mains.
SA Water is undertaking the following four programs in support of its sustainable development commitment:
- Improving the quality and reliability of drinking water in the Anangu Pitjantjatjara Yankunytijatjara (APY lands).
- Providing free drinking water fountains across the state and encouraging reusable drink bottles.
- Supporting community partnerships that share our vision of water management, education and conservation.
- Creating zero cost energy future through solar-powered water treatment plants.
