At the London Aquatics Centre, four independent water treatment plants are provided. Circulation within each pool takes account of the movable floors and the traversable booms, and the routing of all pipework is such that no pipework is buried underneath either of the pool tanks. This is an important design consideration should remedial works ever be required on the distribution pipework. The water treatment system incorporates PAC flocculation, medium rate filtration on single grade sand beds, photo-oxidation using ultraviolet, heating, pH control and residual disinfectant control using chlorine. Backwash water is recovered for WC flushing; VSDs control pump flows.
