Aqualuz – Safe Drinking Water for All

Millions of people do not have access to clean drinking water. To help solve this problem, Anna Luísa Beserra Santos created an affordable device that uses the sun to purify water in cisterns.

Today, 785 million people lack safe drinking water, and 2 billion people don’t have access to a toilet. Diarrhoeal disease is a leading cause of death worldwide. For these men, women and children, clean water would help turn problems into potential – unlocking education, economic opportunities and improving health.  

Using technology to support rural communities 

Anna always wanted to be a scientist, and at the age of 17, she overcame financial and technical challenges to design Aqualuz. This cheap yet efficient device uses the sun to purify water in cisterns (for up to 20 years), with no need for chemicals or complex filters. 10L of treated water costs just US$ 0.02. 

Based on solar water disinfection (SODIS), this innovative filter is an ideal way to meet the needs of communities who use rainwater harvesting systems – in her native Brazil, this represents 1 million people, especially in the semi-arid rural northwest. So, far 1,500 people use the device and have been given training, so that they can actively participate in deploying the technology and become replicators in their neighbourhoods. 

Over the next 3 years, Anna hopes to optimise manufacturing costs and reach 1 million people by taking the technology to other countries in America, Africa and Asia.
