Our global population is about to reach 7 billion, but less than 3 billion have a consistent supply of high-quality water that is regulated.  In the developing world, poor sanitation and lack of sewage treatment can lead to soil and water contamination by pathogenic microorganisms.  The quality and available quantity of safe drinking water correlate with the rate of enteric infections, and in turn with growth shortfalls and cognitive impairment in children.  Each year, 3-4 million people die of waterborne diseases in developing countries, including about two million young children who die from dehydration.

Experience has shown that sustainable solutions to these problems are not easily obtained.  Indeed, providing global communities with sustainable access to potable water is one of the “Grand Challenges for Engineering” as identified by the National Academy of Engineering.

PureMadi is working to create, test, and implement appropriate technologies to improve water quality, human health, and quality of life for the world’s poorest communities.  Our solutions are grounded in sustainability principles that enable communities to help solve their own water problems.


PureMadi works at the intersection of water, societal, and human health disciplines.

Our work is based in the Venda region of Limpopo Province, South Africa.  “Madi” is the Tshivenda word for water.

Our current focus is on the design, testing, and dissemination of ceramic technologies for point-of-use (e.g. household) water treatment.
