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.
An overflow chamber comprising an inlet and an outlet, a screen disposed above the inlet and outlet, whereby flow may take place between the inlet and the outlet without passing through the screen, and an overflow outlet disposed above the screen, at least one baffle being provided in the chamber below the screen, the baffle extending across the general flow direction between the inlet and the outlet.
