Problem Statement:Millions in the villages of India do not have safe drinking water. It is wasteful and costly to boil water with fuel; bottled water is prohibitive. Existing water purifiers are costly and require power, an uncertain commodity in most places.Solution: Portable, solar-powered, home and shop and community water purifier. Easy to maintain and reasonably priced (~₹3,000–₹5,000). Operates using solar energy (requires no electricity). Multi-stage filtration system (sediment + UV + activated carbon). Portable and space-saving design for urban and rural home applications.Implementation Practices:1. Hardware: Portable, rugged solar panel + water filter system.2. Distribution: Direct sales are made to rural households, NGOs, small groceries, and schools.3. Maintenance: Replaceable filter cartridges every 3–6 months (inexpensive.4. Awareness: Simple campaigns on health benefits of clean water.Revenue Model:1. Product Sales: Direct sale of purifier units (~₹3,000–₹5,000).2. Filter Subscription: ₹200–₹300/month for filter cartridges for replacement.3. NGO/Government Contracts: Sets of bulk units for Rural Water Projects.4. CSR Partnerships: Organizations are able to finance units under corporate social responsibilities.Why It Is Successful in India:Affordable for low-income families.Solar-powered setup avoids power problems. Health impact is huge: reduces water-borne diseases.Scalability: Scales up to urban slums, schools, and small businesses. Simple Example: Each person from a selected village buys one ₹4,000 solar water purifier. It is manually powered and produces 20 liters/day of safe drinking water. Every 3–6 months, a new filter is purchased at ₹250 rather than expensive packed drinking water.
