Abstract:
1. A stormwater pollution management apparatus adapted to be arranged in operable combination with a storm sewer pipe, said stormwater pollution management apparatus comprising: a sediment water intake assembly adapted to be supported proximately at an upper surface of water in a stormwater basin, said sediment water intake assembly having a first end and an second end generally aligned along an axis and includes a hollow inverted T-shaped connector, an axially elongated and generally horizontal intake projecting in a first direction from one side of said T-shaped connector and toward the first end of said water intake assembly, with said axially elongated intake defining a series of openings along the length and about the periphery thereof for allowing water to pass into and be guided by the intake toward the second end of said water intake assembly, with said water intake assembly further including a generally horizontal outlet projecting in a second direction from a second side of said T-shaped connector and toward the second end of said water intake assembly for directing water in said water intake assembly toward an inlet to the storm sewer pipe, and wherein said water intake assembly further includes a wrapper operably joined to and extending along and about said generally horizontal intake for creating an energy differential between the sediment water flowing into the water intake assembly and the water in said basin thereby affecting separation of particulate sediment from the water flowing into the water intake assembly; and a hollow riser extending upwardly from said connector and generally normal to said axis, with a terminal end of said riser extending a predetermined distance below an emergency overflow level of said basin, and with said hollow riser defining a passage for viewing water quality flowing toward the second end of said sediment water intake assembly.
