Canal de Isabel II (CYII) is the company that manages the bulk of water supplies for the Community of Madrid. It is primarily owned by the regional administration through the so-called Ente Público Canal de Isabel II, with a minor stake owned by local governments.2
Founded by Isabella II of Spain on Jun 18, 1851, in Madrid.1
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.
