Rainwater and stormwater harvesting

Rainwater and stormwater can be captured, treated and stored for local use. Harvesting of runoff is beneficial to waterways as it removes potentially damaging flows and pollutants, and it also provides a local alternative water supply. Commonly used infrastructure for treatment and storage includes wetlands, bioretention systems, tanks and ponds.

Warrnambool Roof Water Harvesting Project


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.

Kalkallo Stormwater Harvesting and Reuse


The Kalkallo Stormwater Harvesting and Reuse Scheme is the first facility in Australia attempting to harvest and treat stormwater to a standard acceptable for direct injection into the drinking water system.

Waterproofing the West

South Australia

A region wide system that harvests, treats and stores stormwater and distributes recycled water through western Adelaide, sustaining a growing economy and enhancing the natural environment. The project will result in sound water management and will treat and inject up to 2,400ML of recycled water each year.

Currumbin Ecovillage Rainwater Harvesting


The Currumbin Ecovillage is a 147 lot development in the Gold Coast Hinterland with sustainability at its heart. It demonstrates off-grid living and includes large rainwater tanks on each lot to provide drinking water.


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


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.



A Melbourne development planned in collaboration between a water utility and a developer, which includes smart technology to provide rainwater for hot water supply, recycled water supply and real-time monitoring of water use, forthcoming storms and tank levels.

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.

Josh’s House

Western Australia

Josh Byrne led by example by building his own home using environmental principles and proving that sustainability can be affordable. Josh's house includes a range of water sensitive urban design and water efficiency measures.

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.

Collaborative planning for the Fishermans Bend Urban Redevelopment


This scale and profile presented a unique opportunity in building water sensitive cities, as the economies of scale help to support novel infrastructure approaches and ‘best in class’ approaches to water servicing and urban development.

Victorian Planning Provisions Amendment


On 26 October 2018, Amendment VC154 changed the Victoria Planning Provisions (VPP) and all planning schemes, to introduce new stormwater management provisions for urban development and amend State planning policies related to integrated water management (IWM).

Queensland Children’s Hospital therapeutic landscapes


The multi-award-winning Queensland Children’s Hospital is Australia’s largest paediatric hospital and the largest capital investment in children’s health in Queensland’s history.

45 Shand Road, Reservoir


This infill development uses rainwater harvesting and raingardens to meet council flood mitigation requirements, rather than dedicated on-site ‘grey infrastructure’ like concrete pits, tanks and pipes.
