One thing I love about India's approach to water problems is how they mix old and new ideas. For centuries, Indians have built stepwells and tanks to collect rainwater. Now, companies like Rainstock are updating these ancient designs with modern materials and monitoring systems.
In Rajasthan, I visited a community that had revived their old stepwell with Rainstock's help. They added filters and sensors while keeping the traditional stone structure. Now it provides clean water to the entire village year-round, even during the dry season.
Natural Filtration Systems Inspired by Village Practices
In many Indian villages, people have traditionally used layers of sand, charcoal, and gravel to filter water. PureEarth Technologies has taken this idea and made it better with scientific testing and standardized materials.
Their "BioSand" filters cost just 1,500 rupees and can last for years with minimal maintenance. When I helped install one in a rural school, the teachers were amazed that such a simple device could make such a big difference in water quality.
Affordable Solutions for Every Budget
Community Water Centers: Sharing Resources
Not everyone can afford their own water purifier. That's why companies like JalKalp are building community water centers where people can get clean water for less than 1 rupee per liter.
I visited one of their centers in a slum area of Mumbai. Before the center opened, people were paying 10 times more for bottled water that wasn't even properly purified. Now, over 500 families get clean water daily at a price they can afford.
DIY Purification Kits for Rural Homes
Swachh Jal has developed do-it-yourself water purifying systems costing under 2,000 rupees for groups in isolated places. Every package has easy directions, chlorine pills, and basic filters.
When I helped distribute these kits in a village in Bihar, even children quickly learned how to use them. The local health worker told me that cases of diarrhea had dropped by 70% since the kits were introduced.
