Major water recycling plan for Sydney

Air conditioning coolers: water could be headed for Sydney toilets

The City of Sydney is considering a public private partnership joint venture to take water recovered from airconditioning cooling towers and sewage for use in laundries, flush toilets and to water public parks.
The council is developing a business case for the project to provide recycled non-drinkable water in a business case expected to be finished by December.
The PPP model could see a water services company finance, build, operate and maintain a citywide network which takes supplies from domestic wastewater, rainwater and airconditioning cooling towers.
“Most of Sydney’s water is treated to potable or drinking quality, yet only 2 percent of it is actually used as drinking water,” the council says in its submission to the Productivity Commission.
“Even after taking into account all the other uses for treated water, such as food preparation and cooking, less than 20 percent needs to be of drinking water.”
