The San Diego County Water Authority issued a public notice on July 8, 2019, informing water customers of a malfunction that occurred on April 21-22 at its Twin Oaks Valley Water Treatment Plant, which treats water for distribution to Carlsbad residents and several other cities in San Diego County. Properties in Carlsbad Municipal Water District and Vallecitos Water District will receive a postcard mailer detailing the incident.
The water supplied to Carlsbad residents and regionwide during the incident continued to be safe for all uses due to additional treatment processes in place, and corrective actions were taken immediately to prevent similar problems in the future.
