Water Quality Report

The Annual Water Quality Report is provided by the Castaic Lake Water Agency, Valencia Water Company and the other two Santa Clarita Valley retail water purveyors. A report is published every year in the month of July and mailed to our customers. Our goal is to provide our customers the most up-to-date information about our water.
