Water Sensitive Urban Design

There is increasing recognition around the world of the threats facing urban environments and their water resources. In many cities water demand is approaching or exceeding limits of sustainability, leading to increasing interest in alternative water sources, such as stormwater harvesting, wastewater recycling and desalination. At the same time, receiving environments such as urban streams and bays are threatened by pollution and erosion from stormwater runoff, or eutrophication due to discharge of poorly-treated wastewater. There is also increasing recognition of the importance of water in the urban landscape, and of its role in the welfare and health of humans.
