An overflow chamber ( 2 ) is provided for use in a combined sewer overflow. An inlet ( 12 ) and an outlet ( 14 ) open into the chamber ( 2 ) below a screen ( 20 ), and an overflow outlet ( 15 ) opens into the chamber above the screen. Baffles ( 26 ) are provided underneath the screen ( 20 ) across the general flow of storm water. In storm conditions, the storm water in the chamber ( 2 ) will reach the level of the screen ( 20 ), which traps aesthetically offensive material and gross solids, leaving the water to flow through the screen ( 20 ) to the overflow outlet ( 15 ). The baffles ( 26 ) circulate the storm water, and this dislodges material accumulated on the underside of the screen ( 20 ) and so helps to prevent blinding of the screen ( 20 ) in storm conditions.
