WSUP is a not-for-profit company that helps transform cities to benefit the millions who lack access to water and sanitation. We were created in 2005 as a response to the urban explosion that has left many cities unable to provide basic services, such as access to a toilet or drinking water, to low-income communities. We work alongside local providers, enabling them to develop services, build infrastructure and attract funding so that they can reach low-income communities. To ensure that services can reach as many people as possible, and will exist over the long-term, we have a strong focus on financial viability. This means working with utilities and businesses to build services which generate revenue whilst reaching the most vulnerable urban residents, and advising regulators and governments on how to create an environment which enables businesses to succeed. We are based in the UK with offices in seven countries in sub-Saharan Africa and Asia. As the urban specialist in water and sanitation, we are committed to sharing evidence and approaches so that our innovations can enable change around the world.
