About us

Our Beginning 

In 2015, Blue Tap founder and CEO, Francesca was working for charity Médecins Sans Frontières (MSF) providing clean water and sanitation for healthcare centres in sub-Saharan Africa. While working for MSF, she ordered chlorine dosing technology, designed to treat water to drinking standards. The technology cost the same as the average annual household income in many countries across the world.

We saw an opportunity and a need – for simple, affordable chlorine dosing technology - designed to reduce the number of people drinking contaminated water across the world. We are obsessed with clean water. We know the impact that it has on health, gender equality, children’s education and a myriad of other socioeconomic goals.

Sustainable Development Goal 6

Clean water is the bedrock of good public health, and now more than ever, after the Covid-19 pandemic, we want to ensure the global population’s health is as good as it can be. Good health starts with good water access. We are committed to supporting the achievement of Sustainable Development Goal 6 in every country across the world.
