Water purifying tablets and filters are common in some of the places where we work. They can be vital as a short-term solution, such as in the aftermath of natural disasters when water sources have been affected. But these products aren’t suitable as a long-term solution to the water crisis. The industry required to manufacture and deliver enough to all of the millions of people around the world still in need of clean water, every single day, would be impossible. But more importantly it wouldn’t be fair. Making the world’s poorest people use short-term solutions as long-term answers creates a two-tier system. Everyone deserves access to the same thing – a local, sustainable supply of clean water as a service.
