Harnessing sunshine and seawater to produce safe drinking water where groundwater has turned salty.
01The challenge
Along the Bay of Bengal, sea-level rise and storm surges push saltwater into aquifers and ponds. Families pay more, and walk further, for drinking water.
A system that uses solar energy to desalinate seawater or brackish water, designed for high irradiation and complex water types.
Engineered to be the lowest-cost sustainable option where water provisioning is expensive, so it can be maintained locally.
03Community
Being designed with coastal communities facing the highest salinity and water costs.
04Impact
Figures are published once they have a source. Each carries its evidence status. How we measure.
Litres of drinking water per day: figure pending verification
