    Excellent, just what we are looking for. The NGO I work for has been looking for a solution to contaminated water and have considered biosand filters. We have a policy to find solutions to problems that have the least possible outside intervention so as not to foster dependence on out side help. Manufacturing filters with the steal moulds even locally has its drawbacks, but now we can begin training users to make their own filters with the design on the CMS website.
