Stormwater is rainwater that runs off surfaces such as lawns, roads, roofs, car parks and natural ground. We maintain stormwater infrastructure to drain rainwater away to prevent flooding in built-up areas. Stormwater is not wastewater – it flows into our waterways untreated.
We maintain over 2500 kilometres of stormwater drains. Each year we implement a range of projects to maintain and upgrade our stormwater infrastructure. This program of works aims to:
Landholders and developers are legally responsible for managing stormwater runoff from their properties. For information, visit Stormwater drainage.
Water sensitive urban design is an approach to the planning and design of urban environments that supports healthy ecosystems through smart management of water.
As part of our urban sensitive design approach, we maintain over 1500 devices which improve the quality and control the flow of stormwater runoff into the city's creeks and channels. These include:
Stormwater drainage and water sensitive urban design standards are applied to new development and other activities through the City Plan.
