Reducing pollution
Reduce pollution getting to our waterways
All stormwater ends up in our waterways and the harbours, so everyone is responsible for reducing pollution getting into our stormwater system.
Wash your car on the grass
The water runoff from washing your car contains heavy metals and detergents. This runoff, when washed on concrete or on the side of the road, can enter our stormwater network and flows untreated into our local waterways and ocean.
Wash your car on the grass as it allows the dirty and soapy water to be absorbed into the ground, filtering the water and preventing it from washing into a stormwater drain.
Or use a commercial car wash facility where the runoff is connected to the wastewater network, therefore the water will be treated before being returned to the environment.
Pick up dog poo and throw it in the bin
Dog poo contains harmful bacteria like E. coli. When dog poo is left on grassy areas, footpaths, and berms, bacteria can end up our stormwater network when rain washes it onto roads, letting it flow, untreated into our local waterways and oceans.
Fix car leaks
Oil and other petroleum products are toxic to aquatic life and our waterways so it’s important to regularly service your vehicle. This stops oil from leaking from your car/motorbike/lawnmower onto the road and then into the stormwater network. It only takes one litre of oil to contaminate a million litres of water. Remember oil and water don't mix!
Don’t pour hazardous substances into household or stormwater drains
Paints (oil and water based) and thinners are toxic to aquatic life, and cause discoloration of streams. Make sure you read the instructions on the container label and clean and dispose of paints, thinners, and other hazardous substances responsibly. Be careful to clean up after any spills and don’t pour any chemicals into household or stormwater drains.
Each council has its own hazardous substances page on their website which has information on the disposal and cleaning of hazardous substances:
