Water - Who We Regulate

PUC's Role

The Oregon Public Utility Commission (PUC) regulates a portion of the state’s 3,500 water systems. The PUC oversees some investor-owned water utilities, as well as select mobile home parks and associations providing water service. The PUC does not regulate any of the 1,100 municipalities and publicly-owned water systems that serve a majority of Oregonians.


All regulated water utilities must comply with PUC service rules and regulations, such as water quality, pressure, customer service, plant repair, and maintenance. The PUC investigates complaints to ensure customers are receiving safe and adequate water service.


A small number of these regulated water utilities must also comply with PUC rules governing rates to ensure residents are receiving service at just and reasonable rates.
