The biosand filter is a simple, cheap and effective small-scale adaptation of the traditional slow sand filter that contains layers of sand and gravel. Our local partner Wennuan Shuibei was tasked with organising the plastic buckets and pipes required to build the BSFs. The local schools were responsible for organising the stones and gravel.
