This article explores the contribution of stormwater overflows to the pollution of receiving waters in Great Britain. Three sets of Storm King Overflows (SKO) have been constructed by Southern Water on a combined sewerage system in Bexhill, England to control, attenuate and screen the discharge of stormwater from the drainage area. The device is a hollow cylindrical vessel with a dished base and a flat top. The geometry of the interior and the shape and placing of the entry jet are carefully arranged so that flow entering the device must follow a predetermined path through the vessel. The Egerton Park Stream is a small urban stream which rises to the north of Bexhill, flows through the center of the town and then discharges onto the beach to the south of the town. The efficiency of a SKO can be looked at in two ways: in chemical terms and aesthetic terms. Chemical efficiency means the ability of the device to remove common pollutants such as suspended solids, biochemical oxygen demand and ammoniacal nitrogen from the flow before discharge to the stream. Aesthetic efficiency can be defined as the ability of the device to remove neutrally buoyant sewage solids from the flow before discharge. |
