Canal de Isabel II

From Wikipedia, the free encyclopedia

Canal de Isabel II (CYII) is the only company that manages the water supplies for Madrid, Spain. It is owned by the Autonomous Community of Madrid.


The Y in the abbreviated form of the company's name is from the old spelling Ysabel for Queen Isabel II, during whose reign a modern water supply was provided for Madrid. A canal was constructed to provide water from the catchment of the river Lozoya.

The water entered the city through its northern suburbs using gravity.
