Abstract
A drainage system for separating oil and debris from water run-off wherein a chamber in the path of flow of the run-off includes a downwardly inclined screen and a debris-collecting fence beneath the screen to maintain separation between the debris and water; and an organic absorber may be positioned in the path of flow of the water beneath the screen to remove organic oils from the run-off.
