How solar water purification works
Award-winning technology delivering 10,000 liters daily
Developed by a Forbes 30 Under 30 team with backing from Goldman Sachs. Our OASIS Box™ combines solar power, advanced filtration, and real-time IoT monitoring for complete transparency.
The Purification Process
From contaminated source water to safe drinking water in five stages
Solar Power Collection
Photovoltaic panels capture sunlight and convert it to electricity, enabling off-grid operation in remote areas without electrical infrastructure.
Pre-Filtration
Water passes through sediment filters that remove large particles, dirt, and debris, protecting downstream filtration stages.
Multi-Stage Filtration
Advanced membrane filtration removes bacteria, viruses, parasites, and harmful contaminants down to microscopic levels.
Quality Monitoring
IoT sensors continuously measure Total Dissolved Solids (TDS) and other water quality parameters in real-time.
Safe Water Dispensing
Purified water is stored and dispensed to community members, with digital flowmeters tracking every liter produced.

Frequently Asked Questions
How does solar water purification work?
Solar water purification uses photovoltaic panels to power filtration systems that remove contaminants from water. The OASIS Box combines solar power with multi-stage membrane filtration, sediment removal, and continuous quality monitoring to produce safe drinking water without grid electricity or fuel.
Is solar-purified water safe to drink?
Yes. The OASIS Box uses advanced filtration that removes 99.9% of bacteria, viruses, and contaminants. Real-time TDS (Total Dissolved Solids) monitoring ensures water quality meets WHO standards. Each unit is equipped with IoT sensors that track water quality continuously.
How much water can an OASIS Box produce?
Each OASIS Box produces up to 10,000 liters of clean water per day, enough to serve approximately 250 people (at 40 liters per person daily). The actual output depends on sunlight availability and source water conditions.
What maintenance does the OASIS Box require?
The OASIS Box is designed for community maintenance with simple procedures: regular filter cleaning, periodic filter replacement, and basic system checks. Bondh E Shams provides training to local community members and remote monitoring support through our IoT dashboard.
How does this compare to boiling water?
Boiling requires fuel (wood, charcoal, or gas), produces CO₂ emissions, and takes significant time and effort. The OASIS Box uses free solar energy, produces zero emissions during operation, and provides continuous water supply without manual effort. Each unit saves approximately 272 tons of CO₂ annually compared to biomass boiling.
What is the Gold Standard carbon certification?
Gold Standard is a certification body sanctioned by the UNFCCC (United Nations Framework Convention on Climate Change) that verifies carbon offset claims. Bondh E Shams carbon program deployments undergo rigorous third-party audits to validate the CO₂ reductions from replacing biomass-based water boiling.
