The water paths of Barcelona

Barcelona city drinks from three catalan rivers, Llobregat (40%), Besòs (10%) and Ter (50%). But, which is the water’s journey until it arrives into our water taps?

The process begins with water gathering from the rivers, to be treated in purification plants. Once water achieves the sanitary standards, it is stored, transported and distributed through a complex pipe system.  Then water arrives to Barcelona’s citizens to be used.

Water that after it’s consume has become residual, goes to the sewers and finally ends up into water treatment plants (the 70% of the city’s residual waters are treated in the Besòs treatment plant), where the impurities will be eliminated and water will be used in secondary uses or will arrive to the environment, closing a cycle that will start again.
