Approaching the first year of implementation, the GreenLED consortium met at the end of May in Madrid to share the progress of this unique project. This project will create a reference in climate adaptation by demonstrating that rainwater can be a reliable source of water to meet growing urban water demand, meeting the regulatory constraints for public health and rainwater reuse in cities.

The space needed for water retention and infiltration in urban areas is typically limited. This results in conflicts with other uses of space, and in solutions that are expensive. With the Urban Waterbuffer (UWB) rainwater in urban areas can be purified and retained for a longer time, without obstructing other spatial functions.
