The integrated water cycle


The journey begins in the different installations for capturing the river’s water.

Canal makes use of both surface water and underground water in order to be able to provide the amount of water necessary to supply all of the Madrid region’s inhabitants.

The collection of surface water is carried out by using water from the Rivers Lozoya, Jarama-Sorbe, Guadalix, Manzanares, Guadarrama-Aulencia and Alberche through reservoirs and diversion dams and the Tajo drinking water treatment plant (DWTP).

The incorporation of groundwater into the Community of Madrid supply system makes a greater volume of water available to address demand during periods of drought, when the volume stored in surface reservoirs deceases.

Madrid owes its name to the Arab settlement Magerit, which means “riverbed”, and which in turn was located on the site of a Visigoth settlement called Matrice, which means "creek".

The water stored in our reservoirs could fill 700 football stadia, such as that of Real Madrid.

The 944 hm3 of water stored in our reservoirs could supply the Madrid region for a year and a half.

The water that Madrid consumes in a day and a half could fill the Torre Picasso building 5 times over.
