Stormwater Terms

As part of the urban water industry, we use many phrases and terms that may not be common to hear. The most important terms we use are stormwater and WSUD. Water Sensitive Urban Design (WSUD) is the design of buildings, subdivisions, and works to minimise the impact of development on the surrounding environment and waterways. WSUD involves treating and reducing stormwater flows, increasing soil moisture, urban greening, and providing an alternative water source.

Stormwater, or rainwater runoff, is rainwater that runs off land and moves away from the area where it originally falls. In urban or built-up areas, it is best defined as rain that runs off surfaces where water cannot penetrate such as roofs, driveways, and roads. It is carried away by a series of pipes known as the stormwater drainage network to our natural water bodies—creeks, rivers, and the sea. Click ‘read more’ for a list of common stormwater terms.
