Spring Street - Baramy Gross Pollutant Trap

Cockerill Contracting were commissioned to build two GPTs as part of the Blackmans Swamp Creek Catchment. This project was the winner of SIA 2009 National Stormwater Excellence Awards for Stormwater Harvesting and Reuse.

As noted in the Conference Proceedings of the Stormwater 2010 Conference,

Managing water quality is a critical factor in the success of the harvesting scheme. Urban stormwater can include a range of pollutants that left untreated or unmanaged, pose a threat to the city s raw water supplies. …The source of stormwater pollutants in an urban setting ranges from atmospheric deposition to direct discharge … Major components and how they operate are described … Two large Gross Pollutant Traps (GPTs); one located on Blackmans Swamp Creek at Dalton Street and the other on a major piped drainage line near Margaret Stevenson Park. These are designed to remove a portion of the larger pollutants from the runoff. …The two gross pollutant traps removed approximately 800 tonnes of litter, rubbish and organic matter from Blackmans Swamp Creek in the first year following installation.1”
