Stormwater (untreated rain runoff from hard surfaces such as roofs, roads and footpaths) can easily become polluted as it washes away litter, animal waste, oils and chemicals into our waterways.

Polluted water makes it hard not only for people to enjoy activities like swimming or fishing, but also harms wildlife and plants. Be part of the solution by using and disposing of products thoughtfully as we clean up our streets and creeks.

For maps on your local catchment or information around flooding requirements for development applications see Floodplain Management.
