As part of our commitment to improving water quality and the environment, we're installing a new Gross Pollutant Trap (GPT) in Yarra Bay.

The new GPT will be located at Korringal Ave, near the sailing club. It will connect to the storm water drain, which currently flows underground and releases into the bay.

Work began on Wednesday 15 June and will progress for approximately four weeks, with an estimated completion date of mid-July, dependant on weather.

How does a GPT work?

When it rains, water flows to our beaches through the underground storm water system. As it flows, the water picks up rubbish, organic matter and contaminants from roads and footpaths along the way and takes it through the drain and into the ocean.

Gross Pollutant Traps are installed to prevent rubbish and debris from reaching the ocean. The traps are installed before the water reaches the bay, and work by forcing the storm water to bypass through a vortex that spins to remove silt, organic matter and large items.

We currently have approximately 40 gross pollutant traps across Randwick City, which combined collect more than 300 tonnes of  rubbish from entering our oceans each year.
