The document analyzes the feasibility of low-cost water filters in the village of Manipura in Karnataka. It finds that the village suffers from inadequate and low-quality drinking water. Most villagers boil or treat water before drinking but are unaware of affordable filter brands. The study proposes distributing low-cost filters costing Rs. 700-1000 through local women's self-help groups, with financing support. This could provide clean water access to 500 households while promoting local public health. Key challenges include ensuring continued filter use and managing any loan defaults.
