Water Quality

Delivering high quality water to Anaheim residents and businesses has been a core responsibility of Anaheim Public Utilities for more than 125 years.

We closely monitor the quality of water we deliver to you and our other customers. Many of the issues that water providers are facing are a result of industrial and manufacturing processes that have made their way into the water table for decades. Each year we conduct more than 44,000 tests on samples drawn from our own facilities and from customer locations throughout our service area. Our tests are in addition to thousands of tests conducted by our water suppliers. We test for over 100 possible substances in our drinking water, most of which are not detected at all in the water we deliver to you.

All of our tests and behind-the-scenes efforts are aimed at one goal: making sure that your water consistently meets all the standards set for quality by California and federal regulations.
