Bruce Schauer was given the challenge to redesign the way sand filters are made with concrete in a way that would be low-tech, cost-efficient and duplicable. After experimenting with several different materials, he began to use a material that is very common throughout the world – corrugated iron roof sheeting. Instead of an inside mold made of metal, Bruce’s design uses a weak concrete mix that is broken out after the filter is poured This unique design fits perfectly in Seeds of Hope’s philosophy of  a graduated “next easy step” ladder of technology for community development.

One of the things that has been missing in community development projects and often leads to failure is the lack of options.  The world is not a one-size-fits-all world, but instead it is incredibly diverse. 

So, what’s needed is to bring solutions whose applications can fit different types of communities.  Bruce’s unique design can easily be the first step in rural sand filter production and he hopes that it will benefit many people.
