In the next 24 hours, the world’s urban population will grow by nearly 200,000, and they all need decent water and sanitation. In developing countries, city authorities are struggling to cope with this demand.

Since 2005, a number of far-sighted organisations have chosen to work with WSUP to address this issue, recognising the success of our approach.

Our partners recognise the scale and urgency of the challenge, and have seen that WSUP has developed a series of methods that are effective and are setting the foundations for providing sustainable water and sanitation services in cities, at scale.

As urbanisation gathers pace, we urgently need more support so that we can scale up our work. From 2016-2020, we plan to reach 17 million urban residents with improved water, sanitation and hygiene services – and we are looking for like-minded partners to help us turn our vision into reality.

“WSUP is a valued partner in helping us to build sustainable communities through access to clean water and sanitation delivery. We are delighted to expand our impactful partnership with WSUP under the RAIN initiative.”

“The Stone Family Foundation regards WSUP as a leader of new thinking and an influencer of innovative practice in the delivery of water and sanitation services in emerging markets. Its business initiatives and programmes are on the forefront of delivering effective market-based solutions to respond to the challenge of rapid urbanisation, and as a result often act as a template for expansion of work by government authorities, private sector organisations and international institutions.”
