Affordable Water Purification for Rural Areas
Real-world problem: In many villages, people still drink water straight from rivers, ponds, or handpumps because they don’t have other options. Sadly, this often leads to diseases like diarrhea, cholera, and typhoid. Families end up spending money on treatment instead of education or daily needs, and kids miss school because of poor health.
Gaps in current solutions: Most water purifiers we see in cities are too costly or need constant electricity. Bottled water isn’t practical either—it’s expensive and not something families can rely on every single day. That leaves a huge gap for rural communities who just need something simple and affordable to make their water safe.
Who benefits: Villagers, disaster relief teams, low-income households, and even people who travel to remote areas. Clean water changes lives—it means fewer hospital visits, healthier kids, and less stress for families who already struggle with so many challenges.
Why this problem matters to me: I’ve seen how unfair it is that something as basic as clean water is still a luxury for so many. It feels personal because I believe everyone deserves safe water, not just people living in cities. If a low-cost solution can prevent suffering and save lives, then it’s worth working on.
Technical details: My idea is a small, portable purifier that runs on solar power. It would use UV light to kill germs and a carbon filter to remove dirt and bad taste. Since it doesn’t need electricity, families in villages can use it daily, and it can even help in emergencies like floods or droughts.
