StormVault is unique from other products in the market in many ways, the most notable being that it is designed to mitigate downstream erosion and watershed degradation through detaining and slowly releasing the flow from each storm event, offering both volume control and treatment in a single structure.
In a suitable sized and installed StormVault, where the detention time is optimized to promote sedimentation of particles less than 70 microns, the StormVault system will collect and hold floatable debris, bed load particulate material, oil and grease, low solubility and other insoluble petroleum hydrocarbons, settleable sediments, and pollutants including metals, nitrogen and phosphorus nutrients, and organic compounds that may absorb or adhere to the surface of solids in stormwater runoff.
1. Diverted stormwater runoff flows through an inlet pipe into the StormVault™ structure.
2. The captured runoff flows through a sediment baffle, energy baffle, and trapezoidal exit baffle.
3. The treated runoff is released into the ground with minimized resuspension and peak flow attenuation.
