Water cycle for cities

Expensive water supply and sewage disposal systems have been created to transport clean water to the city and to discharge waste water. This is very inefficient, say Environmental Technologists at Wageningen UR.

They calculated that Dutch cities can reduce the amount of water they need to import with as much as 50%. Cities can do this by using rain water and by re-using cleaned wastewater. They can also extract scarce resources such as phosphate from sewage. This knowledge of water cycles can be used by city planners across the world. This is how Wageningen UR contributes to improving the quality of life.
