Pollutant Control for Inlet Protection

Abstract

A pollutant control apparatus for mounting in a grate frame used for protecting a water inlet comprising a basin frame and a flexible basin. The basin frame is adapted for disposition upon the grate frame. The flexible basin affixed to the basin frame is made of an open mesh material. In a curb and gutter water inlet, the pollutant control apparatus can optionally further comprise a fabric filter and an inset. The fabric filter is disposed substantially within the flexible basin frame for collecting sediment. The inset is disposed adjacent to the basin frame for securing the fabric filter against the basin frame. The present invention can also be used in a manhole water inlet. In another embodiment of the invention where the water inlet further comprises a shaft disposed under the grate frame, the basin frame further comprises an extension member affixed to the basin frame. The extension member is adapted for attachment to the water inlet shaft.
