Storm water do's and don'ts

Any household waste that is dumped or washed into stormwater drains flows into our streams, lakes or sea. Even small amounts can build up and become toxic to wildlife.

How can you help?

Please, don't ever dump hazardous materials into stormwater drains or the gutter. Some can be recycled and others should be disposed of at your local transfer station or landfill. We can provide you with any information you may need about recycling and disposing of hazardous materials.

If you see pollution in or near a waterway, contact the 24-hour pollution hotline - 0800 800 033.
