A Bengaluru resident’s simple rainwater harvesting system is helping apartment complexes cut up to Rs 1 lakh in monthly water tanker bills, recharge groundwater, and inspire over 200 communities to adopt sustainable water solutions.

In Delhi-NCR’s urban sprawl, Ramveer Tanwar — a former engineer — has been reviving dying ponds through community-led efforts. His initiative, Jal Chaupal, has helped restore over 80 wetlands across India, improving groundwater, biodiversity, and local pride.
