Canal de Isabel II

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.

History

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.
