Gross Pollutant Traps (GPTs) are placed to intercept stormwater pollution prior to its entry into rivers. GPTs function as filters, trapping trash while permitting water to pass through.
GPTs may also serve as a pre-treatment for stormwater harvesting systems. They prevent trash from entering the system while allowing water to flow through.
GPTs accumulate trash over time. They must be cleaned so that water can flow freely through them and so that garbage does not leech into the water.
As stormwater travels through the GPT, it is filtered to eliminate waste and trash.
The function of a Gross Pollutant Trap is to prevent huge debris, silt, and contaminated liquids from entering the storm water system and making their way to the ocean. There are a variety of types available on the market today, and their performance varies based on the weights imposed upon them.
Some of the more fundamental Gross Pollutant Traps placed in areas where demand is expected to be minimal will consist of a 600mm square pit with a grated inlet and a depth of up to 3 meters. These devices, which are manufactured in Australia by Fox Environmental Systems, rely on a progressive deposition of trash at the foot of the pit.
The exit to the street table or onsite pumping station is positioned so that the pit will constantly contain water, allowing toxins to remain on-site. This product’s outlet is available in either 150mm or 225mm dimensions. Companies such as ours execute scheduled maintenance at regular intervals to maintain the functionality of the storm water infrastructure.
SPEL Stormceptors are utilized in more sophisticated, high-demand situations, such as an airport or a petroleum storage facility. Depending on the surrounding infrastructure, these can be up to 12 meters in length and installed up to 10 meters below ground. These types of Gross Pollutant Traps may be utilized to treat the storm water from a whole suburb prior to its transportation via a massive pumping system to the ocean. These types of systems rely on a more intricate method for waste management.
In the first chamber, heavier particles that enter first will sink to the bottom, including silt, various granular deposits, and plastic, among others.
The second compartment will allow liquids such as gasoline and oil to rise to the surface for future collection. When the Stormceptors have reached their capacity, the alarm will recognize a high level of hydrocarbons and a flashing beacon will be emitted to alert the property’s occupants that the first chamber’s silt sediment and floating debris must be vacuumed out, and the second chamber’s contents must be skimmed to remove oils, etc.
