A washing-area drainage trough (10) comprises a sloping-walled drainage channel (12) having a water flow surface defining at least one fall, at least two predefined recessed waste-water outlet locators (14) in the water flow surface, and at least one bridging element (16) locatable in at least one of the recessed waste-water outlet locators (14). The in use bridging element (16) has an upper surface (56) which lies flush or substantially flush with at least a portion of the water flow surface to define a smooth or substantially smooth flow path transition between the water flow surface of the drainage channel (12) and the bridging element (16). |
