Water Sensitive Cities
The water sensitive approach integrates ecologically and economically sustainable water infrastructure (also known as nature-based solutions) into buildings and landscapes.
Decentralised water infrastructure is implemented at dwelling, neighbourhood, and precinct scales to harvest rainwater/stormwater, recycle wastewater, and protect against flooding and environmental pollution.
Wastewater is managed locally, using natural passive treatment processes such as constructed wetlands and soil-based filters. Stormwater runoff is conveyed using swales, surface wetlands, and biofiltration gardens, to minimise flooding and environmental pollution. Locally sourced water is used for a range of domestic purposes and economic activities—such as in novel systems of vertical and horizontal urban agriculture—while green spaces increase local amenity.
