Reducing pollution in stormwater is critical for keeping our urban waterways healthy.
In recognition of the importance of this, the City of Busselton has recently accessed National Landcare Programme funding through the South West Catchments Council (SWCC) to install a Gross Pollutant Trap near Layman Road to remove pollutants from the east Busselton stormwater network.
The City of Busselton’s Senior Technical Officer, Dave McKenna says the new Gross Pollutant Trap will have great benefits.
“The Gross Pollutant Trap will work like a large filter, intercepting and removing litter and other pollutants from the stormwater before it reaches the Vasse Estuary”.
Stormwater can transport environmentally harmful substances into waterways, such as rubbish, sediment, hydrocarbons and excess nutrients. This can impact on waterway health, our local wildlife, tourism, leisure and fishing industries.
Litter can cause toxicity as it breaks down in the food chain, affecting the health of birds, fish and plants. Sediment can also prevent light entering the water, impacting on aquatic plants. Other pollutants like nutrients from garden fertiliser can cause algal blooms.
SWCC’s Waterway Project Manager Pip Marshall says that preventing pollutants from entering the stormwater in the first place can also help.
“We can all help to reduce pollutants entering our precious waterways by disposing of rubbish and chemical waste responsibly, and holding off on fertilising our gardens when there’s rain around.”
The Gross Pollutant Trap will be installed this summer so that it is ready and functioning before next winter’s rains.
This project is supported by the South West Catchments Council, through funding from the Australian Government’s National Landcare Programme.
