Water Safety & Quality

Providing Safe, Reliable Drinking Water is Our Priority

As a community-owned utility, PWP has been serving Pasadena and parts of Altadena for more than a century. With the added benefit of having its own Water Quality Laboratory, PWP’s team is state certified and monitors daily (including weekends and holidays), drawing samples from 300 locations to test for more than 170 elements to ensure the high standards are maintained. Through innovation, conservation and education, Pasadena plans to continue to provide a safe, reliable water supply for generations to come.
