About Water Services
Anaheim Public Utilities Water Services began in 1879 when the leaders of Anaheim took responsibility for operating the water production and distribution system. The original system included 1 shallow well, a 20,000-gallon redwood storage tank and 1 mile of wooden pipeline.
In the following
century we provided the residents and businesses of Anaheim with the water they needed to succeed. As the city has grown we have responded by developing new water systems to meet the future needs of Anaheim. We are more than just a utility – we are an integral part of the community that we serve.
In the following
- 1 acre-foot = approximately 326,000 gallons - The amount needed to cover 1 acre of land (about the size of a football field) with water at a depth of 1 foot; enough water to serve 2 typical families in and around the home for 1 year
- 1 cubic foot = 7.48 gallons
- 100 cubic feet = 748 gallons – The unit of measure used to bill customers
- GPM = gallons per minute, a measure of flow

Anaheim's water supply comes primarily from groundwater pumped from local wells, with the balance coming from purchases of imported water from the Metropolitan Water District of Southern California (MWD).
A cooperative of 26 cities and water agencies serving 19 million people in 6 counties, MWD imports water from the Colorado River and Northern California to supplement local supplies.
