This is Session #6 of the ‘Stormwater Fundamental’ series in 2024, focussing on Gross Pollutant Traps (GPTs). Gross pollutants traps (GPTs) are the oldest form and often most commonly applied stormwater quality improvement device in Australia and overseas. Their success has varied – from preventing the discharge of enormous quantities of litter and coarse sediment into our waterways and ocean, to being completely non-functional or, at times, worsening downstream water quality. This free webinar will include a brief (15 to 20-minute) presentation from Ocean Protect’s Daniel Page and Peter Worth on the history of GPTs, different types (and suitable applications), and key considerations in their appropriate design and management – followed by answers to questions from attendees.
