Over the years, Glendale Water & Power customers have known that they can count on having excellent water quality and water reliability. Each year, GWP sends a water quality report to every customer in the city. Consistently, these reports show that Glendale water meets and, in many instances, surpasses all federal and state drinking water standards.
Water quality is not taken for granted at Glendale Water & Power. We closely monitor your drinking water to maintain its high quality. Each month, we do about 250 different tests on your water and the results are reported to the State Health Department.
