Abstract

The present invention is a filter system for a curb inlet catch basin which catch basin includes a ramp in the curb front which feeds into a catch basin to allow storm water to run directly along the curb and down the ramp and which also has a grated cover so the water can enter directly through the grate. The water collecting trough is mounted inside the curb inlet catch basin at the bottom of the entrance ramp and has raised walls for collecting runoff water. A weir is formed into one of the raised walls allowing the water to run out of the trough. An elongated hydrocarbon collecting boom is removably attached adjacent the weir and positioned for the drain water passing through the weir to pass thereover. The catch basin is removably mounted to the trough adjacent the weir and positioned to receive water runoff from the trough through the weir and over the hydrocarbon collecting boom. The catch basket has a bottom filter screen and a plurality of side filter screens to filter out solid materials from water passing therethrough along with an overflow grate to handle the flow that exceeds the capacity of the catch basket. The catch basket is held adjacent the weir with a pair of clips allowing for the quick removal for cleaning and replacement of the basket. A deflector plate is mounted beneath the curb inlet open grate for deflecting water passing through the grate into the catch basket.
