McRobies gross pollutant trap

A gross pollutant trap is a stormwater management device that captures large amounts of debris, litter, sediment and pollutants before they enter local waterways such as rivers, streams, rivulets and beaches. This helps reduce water pollution and improves the health of aquatic environments.

By capturing large pollutants and debris, the gross pollutant trap helps:

• improve water quality in the Hobart Rivulet by intercepting pollutants from the McRobies Gully stormwater system. This unit increases the storage volume for pollutants from approximately one cubic metre available in the existing "sock" to 9.5 m3 of litter storage capacity and 2000L of oil storage capacity
• reduce the amount of litter and plastic waste in the environment
• protect wildlife and aquatic ecosystems
• enhance the visual appeal of public spaces and water bodies
• protect our native platypus population from entanglement in litter.

The trap captures large pollutants, such as litter, leaves, sediments and other pollutants. It captures them before they enter the stormwater system and flow into natural waterways. This improves the quality of the water entering rivers, streams, and oceans, and helps protect sensitive local ecosystems.

The trap helps improve long-term water quality, reduce pollution in public spaces, and contribute to the overall health of local ecosystems. It's a sustainable investment in Hobart's environmental health and future.

The gross pollutant trap will require ongoing maintenance. This is to remove accumulated pollutants and ensure it continues to function effectively. We will handle regular inspections and cleaning as part of our stormwater management program.
