California American Water is seeking to raise its Monterey area average customers’ bills by nearly 18 percent over a three-year period from 2021-2023. In its latest general rate case filing with the California Public Utilities Commission on July 1, Cal Am is seeking to raise water rates in its Monterey main district to increase revenue by about $8.4 million to cover new capital investment, increased labor expense, higher operations and administrative costs, and increased depreciation. Under the proposal, the “average” Cal Am customer would see their monthly rates increase from about $89.40 to $105.42 over the three-year period.
