Abstract
A system for separating waste materials from a flowing stream of surface water comprises a vertical cylindrical vessel and a vertical structure within the cylindrical vessel. The vertical structure comprises stacked filtering elements and weirs sized to accommodate normal and increased fluid flow for abnormally high surface water flow conditions. The flowing stream containing waste material under normal flow conditions enters the vessel and passes through a filtering wall portion in a lower section of the vertical structure and exits through and effluent pipe. Under higher flow conditions the water flows through an overflow structure mounted on top of a lower cylindrical structure The over flow structure comprises one or more upwardly extending filtering structures and weirs sized to accommodate the excess flow conditions, filter at least a portion of the waste material from said excess flow and direct such excess flow to the effluent pipe.
