The EcoProtector is a primary treatment device designed to remove high loads of stormwater pollutants. The Protector Ecoprotector GPT features an advanced inlet weir, which generates a smooth fluid part to a vortex funnel for the transfer of pollutants into the storage chamber. This innovative design provides superior pollution removal from stormwater inflows resulting in higher water quality. It separates and captures gross pollutants, sediments, silt, total suspended solids, some nutrients, and oil and grease. During a storm event, when there is a large stormwater inflow entering the Ecoprotector, water can discharge freely over the weir to prevent any flow restriction. Captured hydrocarbons rise to the surface of the storage chamber and are retained without resuspension during high-flow events. The outlet riser is integrated into the bypass duct, providing added strength and durability. The Ecoprotector is a fully assembled, one-piece unit manufactured from strong Fibreglass Reinforced Plastic (FRP), which simplifies handling and reduces installation costs due to its weight-saving advantages. The internal surfaces of the device have a smooth finish that resists the buildup of residue, making it easy to maintain. The Ecoprotector GPTs have been engineered to withstand the toughest environmental situations, such as high water tables. They are engineered to BS4994 – 1987 and AS/NZS 1546.1:1998, ensuring high-quality standards. Additionally, MUSIC modeling can be provided to meet specific requirements.
