OSU Students Learn Concrete Water Filtration System

What a treat it was to photograph a two day workshop at Oregon State University taught by David Manz the creator of a brilliant water filtration design.

Mr Manz' elegantly simple design is in use by millions around the globe to bring safe drinking water to people in small villages. In the first day of the workshop students learned to assemble the mold then mix and pour the concrete. 

The next day they safely peeled the steel mold from the concrete filter, smoothed edges and inserted a modified 5 Gal plastic bucket. Mr Manz explained that even in the poorest villages these buckets are plentiful so he integrated that into the design. One filter can purify 40 - 60 liters of pure drinking water each day.

David Manz became my newest hero because he saw a need, created a simple solution that can be built with materials readily available, using limited skill labor and basic tools. He then made his design an open source document and travels the world teaching others his technique.
