Clean Water Wave is run by three directors that all have had both personal and professional experience of working in environments where they have witnessed, first hand, the results of inappropriate water and sanitation technologies being deployed in communities and the devastating results.

Each one of us is passionate about making a difference – not only being able to develop technology that can deliver clean & safe drinking water in any geography but technology that is durable and implemented using a business model that generates enterprise and long-term sustainability.

Founding directors
