The Water Division is responsible for the production, treatment, disinfection, storage, distribution, repair and maintenance of the entire city owned water system. This includes the installation of all new water lines, water main and service repairs, and all fire hydrant repairs. It maintains and operates a water system consisting of eight operational wells, one stand by irrigation well, a Metropolitan Water District service connection, five booster pump stations, six reservoir locations (27.53 million gallons of storage), 27-miles of transmission mains and 128 miles of distribution mains ranging in size from 4 inches to 24 inches, 3731 valves and 916 fire hydrants.


The Wastewater Division maintains and operates the sanitary sewer collection system which consists of 2,800 manholes, seven lift stations with sewer main lines ranging in size from 4 inches to 36 inches in diameter. Approximately 99% of the system is composed of vitrified clay pipes, with less than 1% being cast iron pipe and reinforced concrete pipes. Field personnel use high-pressure jetting to clean lines to maintain the sewer system. The Wastewater Division also maintains 1,000 storm drains, which are periodically cleaned to insure proper drainage during rain events.


The Production Division maintains and operates the water treatment plant. This state of the art facility was constructed in 2008, The water treatment plant on the average treats 1.8 million gallons of water per day, through the process of filtration and disinfection. The water is then piped through the water system providing safe and clean drinking water for Alhambra residents and businesses.
