A gross pollutant trap (GPT) is a stormwater treatment system’s first line of defence. Providing primary treatment, GPTs remove bulky pollutants, plastic pollution, sediment, and litter – and stop their conveyance from our catchments.
Gross Pollutant Traps
Highly engineered water quality devices, deployed directly into the stormwater system to capture contaminants close to the surface.
A vertically configured pollutant trap suitable for low risk applications.
Concrete or fibreglass structures containing a series of sediment settling chambers separated by baffles.
Non-blocking hydrodynamic separator with a unique screen and treatment action, resulting in excellent pollution removal performance and high water quality outcomes.
