Water Sensitive Urban Design (WSUD) is a set of design elements and on-ground solutions that aim to minimise impacts on the water cycle from the built urban environment. It offers a simplified and integrated approach to land and water planning by dealing with the urban water cycle in a decentralised manner consistent with natural hydrological and ecological processes.
- Utilising water saving measures within and outside domestic, commercial, industrial and institutional premises to minimise requirements for drinking and non-drinking water supplies;
- Storage, treatment and beneficial use of runoff (at building and street level, including stormwater);
- Treatment and reuse of wastewater; and
- Using vegetation for treatment purposes, water efficient landscaping and enhancing biodiversity and amenity.
Water Sensitive Urban Design often makes use of biofiltration systems such as wetlands & drainage swales to help clean stormwater before it is released into waterways or used for irrigation, and the City of Onkaparinga has also used a rain garden for this purpose.
