Highly Reliable and Efficient Services for Gross Pollutant Traps and Vacuum Excavation for Industries, Businesses, and Households
Gross pollutant traps (GPT) trap solid waste such as litter and coarse sediments via physical processes. This makes it easier to remove finer sediments from wastewater in the future. These are put in place to catch stormwater pollution before it enters a waterway. At the downstream end of drains or constructed waterways that flow to rivers and urban lakes, gross pollution traps are built. Gross pollutant trap typically consists of a sediment trap with a weir and trash rack at the downstream end. Flow enters through a concrete-lined basin and detained by the weir, improving sedimentation in the process. To manage flow and capture sediments, the system employs a network of underground chambers, screens, and weirs. The waste rack gathers debris from weir overflows. Gross pollutant traps act as a filter, trapping litter while allowing water to pass through. It can also be used to pre-treat stormwater harvesting systems. These provide a cost-effective way to reduce the contaminant lo...
