In Australia

The use of recycled water in Australia has grown over the past decade. Key schemes in NSW, Queensland and South Australia are starting to use large untapped wastewater resources, saving money and preserving our precious drinking water supplies. Read about these projects below:

Rouse Hill

Rouse Hill in Sydney’s north west is currently Australia’s largest residential water recycling scheme servicing more than 20,000 homes with some 1.7 billion litres of recycled water every year used to flush toilets, water gardens, wash cars and for other outdoor uses.

Rouse Hill has reduced demand for drinking water by about 40% on average since the scheme began in 2001 in Acacia Gardens, Beaumont Hills, Castle Hill, Glenwood, Kellyville, Kellyville Ridge, Parklea, Quakers Hill, Stanhope Gardens, The Ponds and Rouse Hill.

Eventually the scheme will serve about 36,000 homes. Find out more.

Pimpama Coomera

Once complete, the program will deliver up to 84 per cent savings of drinking water.

Googong in NSW will set new benchmarks for water efficiency. The 16,000 residents will use less water than a 6,500 resident community. Googong has an integrated water cycle management system with a dedicated water treatment and recycling plant for the town. Recycled water will be used to flush toilets and in the garden. It will recycle half the wastewater produced and stormwater will be harvested and used to irrigate streetscapes, ovals and parklands throughout Googong. Find out more.

Western Corridor

The Western Corridor Recycled Water Scheme in South East Queensland is Australia’s largest recycled water project.

The Queensland Government is constructing the Corridor with Seqwater to protect new and growing populations against climate change and severe drought.

Three advanced water treatment plants have been established as part of the project at Bundamba, Luggage Point and Gibson Island. They draw water from six existing wastewater treatment plants in the region to produce 232 million litres of purified recycled water every day.

The project includes 200 kilometres of pipelines and is worth $2.5 billion - $408 million of this was provided by the Australian Government’s Water Smart Australia Program.
