Cal Water proposes a rate increase effective July 1, 2026.

NOTICE OF PROPOSED RATE CHANGE BEFORE THE CALIFORNIA PUBLIC UTILITIES COMMISSION (CPUC) On or around March 30, 2026, Cal Water will file Advice Letter 2578 requesting authority to increase revenues to recover recently completed and previously authorized infrastructure improvements. In the advice letter, Cal Water requests additional revenue of $537,552, or 0.38% of currently authorized revenue. If approved, effective July 1, 2026, the water bill for a residential customer in the South Bay Region's Hermosa-Redondo area with a 5/8" x 3/4" meter who uses 6 CCF of water per month will increase by $0.28, or 0.7%. Although previously authorized by the CPUC in Decisions 24-03-042 and 20-12-007 as part of the utility's triennial rate review process, the project's cost could only be recovered through a rate increase after it was completed.
