A combined sewer overflow comprises a chamber 1 formed from a length of plastics pipe for ease of off-site manufacture. The chamber has storm and foul water inlet and outlet ports 4, 5 for connection to a drainage system. A baffler 12 and weir 17 is provided to divide the chamber into a normal flow passage 13 and an overflow passage 14. A filter 16 is provided in relation to the barrier 12 and weir 17 so that when the level of sewerage within the chamber rises above the filter, at least some solids are prevented from reaching an overflow 6. |
