Abstract
Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader can split incoming water to pass into dual screen filtration systems. The system can include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and water pressure lines with spray heads for cleaning debris on a sloped floor.
