Gross Pollutant Traps

As part of our commitment to improving water quality and the environment, we're installing new Gross Pollutant Traps (GPTs). The objective of these works is to mitigate the impact of gross pollutants, such as litter, oils, and other debris, entering local waterways through stormwater runoff. This initiative is aligned with the Council’s broader commitment to enhancing water quality, safeguarding local aquatic ecosystems, and promoting sustainable urban water management practices.

What’s Planned?

Gross Pollutant Traps (GPTs) are just one of the strategies Randwick Council uses to help keep our waterways clean. This CDS unit GPT is designed to trap litter, such as plastics, paper, takeaway containers, drink cartons, cigarette butts - anything down to 1mm, and prevent it from entering our waterways. It will also reduce the load of leaves, grass clippings and weed seeds getting into the bushland.  Additionally, it will trap many sediments that flow through our waterways, including the nutrients, hydrocarbons and heavy metals associated with silts and sediment.

There are currently approximately 35 GPTs installed on stormwater lines that lead to local bays in Randwick City. All of the GPTs are cleaned regularly, especially after major rain events that can leave them full of rubbish, branches, and other organic material.

This GPT is called a CDS Unit (Continuous Deflective Separation) and uses an Australian technology that is now the number one way of treating stormwater around the world, including right here in Randwick.

As part of our commitment to improving water quality and the environment, we're installing two new Gross Pollutant Traps (GPTs) in South Coogee and Malabar.
