The South Australian government aims to secure South Australia’s water resources in terms of quality and quantity beyond 2050. The Government’s water security plan, Water for Good, includes a number of commitments to manage water supplies effectively, including the adoption of WSUD measures. While considerable work on WSUD targets has been carried out interstate, climate characteristics significantly affect the performance of WSUD systems. One of the primary purposes for developing interim targets for Adelaide is that they are appropriate for the region and that local data such as climatic information is used.
Through the ‘Institutionalising Water Sensitive Urban Design in the Greater Adelaide Region’ project, potential WSUD targets were identified in three main areas:
Water conservation project targets achieved
Stormwater quality project targets achieved
Stormwater quantity project targets achieved
The interim targets supported policy development for setting water conservation measures for urban households while the quality and quantity targets were aligned with environment and ecological objectives, with a particular emphasis on Adelaide coastal water protection and other sensitive urban water bodies .
