The project has shown that it is possible to deal with a shortage of water in an urban domestic setting, using a cost efficient, quick, ecological and contention free approach. Using a partnership approach, with funding coming through multiple sources (mostly through The European LIFE programme), the project focused on public engagement through the media, educating younger generations, and developing material for its citizens to read.

The impact was substantial. In nine years since the project’s launch, the population of Zaragoza increased by over 12%, yet daily water use reduced from 848,000m3 to 615,000m3 in the same period. Per capita use also reduced from 150 liters/day in 1997 to 99 liters/day in 2012.
