India's Shocking Water Crisis:
A Wake-Up Call

Imagine sending your child to school knowing they might drink contaminated water from an unclean tap. According to UNICEF, less than 50% of India's population has access to safely managed drinking water. WHO reports over 2,000 daily deaths in India due to waterborne diseases, with 2 billion people globally using feces-contaminated sources. By 2025, half the world will face water stress.

This isn't just statistics—it's a daily reality for millions of Indian children, farmers, and workers. But one young engineer from Belgaum, Karnataka, turned heartbreak into hope.

🌟 Meet Niranjan Karagi:
From Playground Observation to Global Innovation

Niranjan Karagi, a 25-year-old Mechanical Engineering graduate, witnessed a heartbreaking scene that changed his life forever. Playing cricket with friends near a government school in Belgaum, he saw schoolchildren drinking directly from taps connected to overhead tanks uncleaned for a year. The water was discolored, unsafe, and deadly.

"I was stirred to say the least," shares Karagi. "These kids deserve better."

His first instinct? Donate a filter. But market research revealed the harsh truth: expensive filters + poor maintenance = no solution for government schools running on shoestring budgets.

💡 The Birth of NirNal: ₹30 Pocket Water Purifier

In 2016, the seeds of NirNal were sown. Karagi's genius? Fit a world-class filter into a discarded PET bottle. No fancy infrastructure needed—just ₹30 and any plastic bottle.

NirNal's 4-Stage Purification Technology:

1️⃣ Netted Mesh (Coarse Particles)

2️⃣ Activated Carbon (Odor + Chlorine)

3️⃣ Cotton Filter (Fine Sediments) 

4️⃣ Ultra-Membrane (99% Bacteria Removal)

Key Features:

• Capacity: 100-300 liters per filter
• Lifespan: 1-3 months
• Child-Friendly: Safe for kids above 5 years
• Visible Results: Murky water turns crystal clear
• Eco-Friendly: Reuses plastic waste bottles

Result? 70% cleaner water at 1/100th the cost of conventional purifiers.
