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.
Contaminated water from sewerage overflows, illegal connections and discharges can enter Port Phillip Bay and make it unsafe for aquatic life and human enjoyment. EPA aims to improve waterway health by minimising contaminants from both point and dispersed sources.
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.
What can you do?
- Understand the difference between the stormwater and sewerage systems; check that your stormwater drains are clean and clear of litter, products and wastes.
- Dispose of water properly, which includes not letting plant, equipment or vehicle wash waters enter the stormwater (your local water authority can guide you on legal disposal to the sewerage system via a trade waste agreement).
- Store and manage liquids and wastes properly.
