USDWE has completed a pilot project funded by Ministry of Social Development about using recycled domestic grey water for agriculture.  Reusing grey water resulting from the sinks located at the schools' yards to irrigate the school's garden instead of using drinking water. It is mainly diversion of grey water (10-12 m³/month) through pipes leading to submerged gravel filter in the garden to be filtered and treated according to standards and then discharged through irrigation network to irrigate the garden. This approach made benefit of the entire amount of wasted grey water without any complications or negative impacts.
