Description
Biosand filter to filter out pathogens in water
Introduction
BioSand Filters are field-tested, low-tech, household appliances that use sand, gravel and natural biological processes to filter out pathogens in water, making it safe to drink.
OHorizons, a non-profit international coalition of innovators, has engineered an award-winning breakthrough in the production of concrete BioSand Filters, a Wood Mold, that can be made with 100% locally-sourced materials, tools, and labor, which reduces the financial and technical barriers to BioSand Filter production.

Including labor each Wood Mold costs between $70-100 and can make around 50 concrete filters in its lifespan. The total material costs for each BioSand Filter (concrete, sand, gravel, outlet tube, diffuser basin, lid, and a clean water storage container) are typically under $25. The filter can clean 44 liters of water per day and serve a family of five in their home for over twenty years if properly maintained.
