Abstract
A gravitational separator for a drainage system includes a collection cavity within which drainwater is collected. The collection cavity includes an exit; and a baffle is strategically arranged within the collection cavity for isolating a boundary region of the cavity interior from the central region thereof and for directing the flow of drainwater which moves through the boundary region along a desired flow path. In addition, an outlet control structure is disposed over the mouth of the exit and includes a sidewall having an opening through which drainwater which enters the mouth of the exit must enter so that as the drainwater enters the sidewall opening and moves into the mouth of the exit opening, the direction of flow of the drainwater is altered through at least 90 degrees.
