Urban migration is leading to a crisis in cities in developing countries, where millions of people lack access to the most basic of services.

Already, nearly 900 million urban residents have no choice but to live in low-income communities – poorly built, often illegal settlements which usually lack even the most basic services like water and sanitation.

Since cities will be the future habitat for many in developing countries, it is critical to invest in basic services and infrastructure. This is the reason why Water & Sanitation for the Urban Poor (WSUP) was set up in 2005.
