<p>A water recycling system including a collection tank (8) and a header tank (22) to which water is pumped from the collection tank (8) through a supply pipe (18) by a pump (20). The supply pipe (18) terminates in a siphon loop so that water from the header tank (22) which has been disinfected by a disinfectant dispenser (42) siphons back down the supply pipe (18) to the collection tank (8). Disinfectant may be added to water before or as it is pumped between the tanks (8, 22) and disinfectant may be sprayed over system elements, such as a filter (9) as pumping occurs and when back-flow of disinfected water to the collection tank (8) occurs. The invention also relates to disinfectant dispensers and filters arranged to flush particles from their surfaces automatically.</p> |
