Overview: 

Washington Water Service Company is a private investor owned utility company that is regulated by the Washington Utilities and Transportation Commission (UTC) in Olympia Washington.  UTC’s job is to protect customers and make sure that rates are fair, just, reasonable and adequate. Oversight by the UTC ensures that necessary improvements are made to the water system, that the system is operated efficiently, and that the company only earns a modest return on the funds it invests in water system infrastructure.
