Canal de Isabel II has reported an incident at the Santillana Water Treatment Plant (ETAP) that has caused changes in the smell and taste of tap water in various towns in the Sierra de Guadarrama since last Sunday.

Residents of the area have voiced their complaints on social media and directly to the Canal, describing a strong "bleach-like smell" and "bad taste" in the supplied water. These issues began to be noticed last Sunday.
Sources from Canal de Isabel II explained that the cause of this alteration is due to a "maneuver" performed on the active carbon filters at the Santillana ETAP on Sunday morning.
Despite the perceptible changes in the water, the public company has assured that it "remains potable and fit for consumption." Therefore, it has been confirmed that the incident does not compromise the safety or sanitary quality of the supply.
To resolve the situation and restore normal service conditions, Canal de Isabel II began purging operations at various points in the network on Monday. The objective is to definitively eliminate the detected alterations and normalize the supply in the affected towns.
