Sun4PureWater, Wupla Enterprise provides affordable portable water and water purification solutions targeting areas that lack access to safe drinking water. The business model empowers communities to own and operate water kiosks to sell safe drinking water to the subscribed households within 1km radius. The water is pumped from a perennial well using energy efficient pump powered by solar PV.

In extension, the business owns a facility for assembling solar powered UV water sterilizers for sales to far-away customers to purify the water in their homes. The enterprise generates revenue from the sales of water and solar powered UV sterilizers to customers in out of reach areas.
