California Water Service Group's Washington Water unit received approval from the Washington Utilities and Transportation Commission for new water rates expected to take effect in October 2026. The new rates are expected to increase Washington Water's annual revenues by $4.1 million, enabling the unit to recover costs tied to investments in safe and reliable water service. Washington Water invested $26.5 million in its East Pierce and Legacy systems during 2023-2024, funding new water mains, treatment facilities, booster pump upgrades, remote monitoring systems and PFAS testing and treatment. The approval adds to parent CWT's broader infrastructure and cost-recovery push: the company invested $276.4 million in utility plant in the first half of 2026 and expects full-year capital expenditures of $580-$640 million. CWT's second-quarter revenues rose 16.5% to $308.6 million from $265 million a year earlier, with rate changes and the Modified Water Revenue Adjustment Mechanism contributing about $15 million and Interim Rates Memorandum Account revenues adding another $15.3 million.
