This Project aims to impact 100,000 under-served people living in the Arusha region over a 3 years period through the adoption of an innovative low-cost sustainable water filter. The filter selectively removes any water contaminant (bacteria, chemicalcontaminants, turbidity, organic-matter) and produces 10 liters/hour of clean and safe water. The filter is locally manufactured and will be customized to local needs. It reduces waterborne diseases and dental fluorosis by increasing access to safe and clean water. The targeted people will be reached through establishment of 1,000 water stations to be operated by local entrepreneurs who will sell water to community members at an a ffordable price.
