The BarterWATER initiative is based on an innovative incentive system that rewards efforts in community action with Rainbow Credits. These credits can be redeemed for clean drinking water from OAS Spring units or exchanged for essential nature-based goods and services, fostering a culture of responsible water use at the grassroots level. 
In addition to the innovative ‘barter-for-impact’ model, the solution is deploying pioneering research from IIT-Kharagpur to tackle Arsenic contamination in the water sources using commonly found laterite mineral for binding and safe disposal of Arsenic. 
Arsenic has had a devastating health impact on communities across at least eight States in North India, where communities lack affordable and easy-to-deploy solutions and suffer from high cancer rates. 
With technological innovation, strong institutional support, and active community participation, the BarterWATER initiative is paving the way for a water-secure and environmentally responsible future, proving that sustainable solutions can be both impactful and scalable.
