Gross Pollutant Traps or GPTs are structures designed to remove litter, debris and coarse sediment from storm water. Only few types of gross pollutant traps, such as our Ecoclean CDS Gross Pollutant Traps and CleansAll Gross Pollutant Traps are designed to remove all types of gross pollutants, including sediment, oil and grease effectively from storm water.
Ecoclean CDS Gross pollutant traps may also be used as pretreatment for flows into a pond or wetland to confine and trap the sediment for easy removal, thus protecting the lakes and waterways from being polluted by gross pollutants and sediment. CDS Gross pollutant traps are commonly used to remove both coarse and fine sediment before the flow enters a filtration device such as a rainwater harvesting tank or on-site detention tank to prevent clogging of the filtration device.

… into a simple & cost-effective system that significantly reduces contamination of our waterways
With normal direct filter screening, particles impact directly on the screen and eventually cause blinding
With CDS indirect screening, particles sweep past screen which remains clear
