Leaves and water flowing into a stormwater drain.

Stormwater is surface run-off from rain and storm events that enters the drainage system. It carries many pollutants, including leaves, sediment, oil and other hydrocarbons, that are a major cause of pollution in our rivers, creeks, lakes and bays.

Improving stormwater quality is a long-term process that involves educating residents and businesses about preventing stormwater pollution at its source and treating stormwater before it enters our waterways.

Cleaner stormwater provides us with new opportunities for stormwater harvesting and reuse. This helps us to protect our precious water reserves.
