Billion Bottle Project recently tested our first bottle with SANTE! This test was a collaboration between BBP and the Obunga SODIS Project in the Obunga slums of Kisumu, Kenya.

Obunga houses approximately 15,000 – 20,000 people and has poor water distribution, dilapidated sanitation services, and high density of housing. These factors contribute to the persistent challenge of diseases such as cholera, dysentery, and typhoid that cause numerous deaths each year. The Obunga SODIS Project, run locally by Drs. Emilly Obuya and Naumih Noah of the United States International University in Nairobi, is a multi-year program focused on reducing Obunga mortality due to these waterborne diseases through SODIS implementation and education.

This first test is part of BBP’s pilot study for SANTE, our low-cost color-changing disinfection sensor. Our partnership with Obunga SODIS aims to integrate SANTE in the local community as a way to make SODIS easier and more effective for its residents. As the pilot study continues, we are eager to elicit feedback from our community partners and the residents in Obunga about how we can continue to develop and improve SANTE and our other solar disinfection technologies.
