Alternative water supplies

The provision of fit-for-purpose alternative water supplies are numerous. Firstly, it enables the conservation of drinking water resources for uses which require water to be highly treated, helping to support water security in times of drought. Secondly, alternative water supplies often remove potential pollutants from the natural environment. In conventional water management models, both stormwater and wastewater carry significant amounts of nutrients and other pollutants into natural water systems, causing ecological degradation, poor amenity and disruptions to recreational uses. Other benefits of alternative water supplies can also include avoided augmentations of conventional infrastructure and increased self-sufficiency for communities.

Central Park Recycled Water Scheme

New South Wales

This is the world’s biggest recycled water facility in the basement of a residential building, which collects wastewater along with stormwater runoff and rainwater to supply non-potable water demands in the precinct.

Warrnambool Roof Water Harvesting Project

Victoria

A landmark scheme which collects water directly from rooftops across a new development and transfers it to a local raw water reservoir where it is treated and utilised as part of the town's potable water supply.

Kalamunda MAR

Western Australia

The Hartfield Park Managed Aquifer Recharge project in the Shire of Kalumunda involves the recharge of an aquifer under controlled conditions in order to store water for
later abstraction for irrigation use.

Currumbin Ecovillage Wastewater Management

Queensland

The Currumbin Ecovillage is a 147 lot development in the Gold Coast Hinterland with sustainability at its heart. Wastewater is treated on-site and provided back to the houses for non-potable uses.

Orange

New South Wales

First of its kind in Australia, City of Orange implemented a stormwater harvesting scheme to supplement their town potable water supply.

South Bank Parklands Rain Bank

Queensland

A public parklands in the heart of Brisbane has implemented an alternative water supply scheme for irrigation and toilet flushing by utilising harvested stormwater and filtered backwash from pools and water features.

Salisbury Alternative Water Scheme

South Australia

Non-drinking water in the City of Salisbury is called ‘Salisbury Water’ and is a mix of treated stormwater and native groundwater which is used to irrigate parks, reserves, schools as well as used in industry and for toilet/garden use in some new residential developments. Collection, storage and distribution of the water uses constructed wetlands, Managed Aquifer Recharge (MAR) and over 150km of ‘purple pipe’ distribution network across the City.

Angus Creek Stormwater Harvesting and Reuse Scheme

New South Wales

The Angus Creek stormwater harvesting and reuse scheme (the scheme) extracts flows from Angus Creek and harvests stormwater runoff from hard surfaces to irrigate the the Blacktown International Sportspark and neighbouring reserves, supplying up to 200ML of fit-for-purpose water each year.
