We Are

Access to safe drinking water is a major challenge across Africa. This challenge became the reason Aqua Clara Kenya (ACK) was founded in 2009, to help different communities have access to safe drinking water using a market-based approach. 


Aqua Clara Kenya is a social enterprise working across Africa to improve access to safe drinking water.  Since its establishment, ACK has been distributing simple, affordable and effective technologies that have enabled more than 300,000 people to have access to safe drinking water.

Our Vision

An Africa where everyone has access to safe drinking water.

Our Mission

To increase access to safe drinking water in Africa by building local capacity, providing effective solutions and implementing sustainable approaches.
