About SDW For All

in the northeast,

How it all started
Science as
a tool for change.
SDW was born from the frustration of a young scientist who realized that creating technology was not enough, it was necessary to take this technology to the field, to the hands of the people who needed it most.
With the dream of being a scientist, Anna Luísa Beserra, from Bahia, created at 15 the Aqualuz, a solar technology for water disinfection. At 17, she founded SDW with the goal of transforming scientific solutions into real social impact.
Her work connects science, frugal innovation, and sustainability to expand access to water and sanitation in vulnerable communities, with data, with rigor, and with field presence.
"I didn't just want to publish articles. I wanted to see clean water reaching the tap, the cistern, the kitchen. That's why I created SDW."
