Solvatten is a combined solar water heater and a water purifier that produces safe and warm water by using solar energy. Put Solvatten in a sunny place and the water will be safe and ready to use in 2-6 hours. An indicator shows clearly when it is safe to drink.
The device inactivates micro-organisms that cause diarrhoea and diseases, producing water which meets the WHO’s Guidelines for Safe Water.
The unit is robust and carries 10 litres of water. It is very simple to use, needs no supplies and is easy to maintain. Its life expectancy is at least 5 years.
Solvatten has been repeatedly recognised for product innovation and contribution to the war on carbon emissions. Families using Solvatten need no longer burn wood to boil water, helping to reduce the massive deforestation problems in these areas.
”The Solar Safe Water System developed by Solvatten AB is an inspiring example of a non-fossil, non-nuclear climate innovation with the potential to substantially reduce greenhouse gas emissions.” WWF (World Wildlife Foundation)
The Solvatten unit was invented and developed in Sweden by a team in Stockholm who are committed to helping the millions of people around the world who do not have a clean water supply. Extensive testing in labs and out in the field in Nepal, Kenya and Uganda has been 100 % successful. Although Solvatten has received much recognition and many awards both globally and at home, the true success lies in the fact that as the number of families benefitting from this innovative technology continues to grow, Solvatten is directly helping the environment in areas where deforestation has been a major problem.
"Before getting SOLVATTEN I spend 420 Ksh (€4,2) on firewood each week. Now I only spend 120 Ksh (€1,2) per week. It used to take three hours every day to collect firewood but now I only spend 1 hour a week." Rosalyn Mwabi
