Washington Utilities and Transportation Commission Sets New Rates for Washington Water Service’s Stroh’s Water System to Help Keep Service Safe and Reliable

GIG HARBOR, Wash., June 04, 2025 (GLOBE NEWSWIRE) -- Washington Water Service (Washington Water), a subsidiary of California Water Service Group (NYSE: CWT), has received approval from the Washington Utilities and Transportation Commission (UTC) to increase annual revenue by approximately $178,000 in its Stroh’s water system and adjust water rates accordingly. This increase in annual revenue will be phased in over two years to reduce the impact to customers, with rates reflecting half of the change effective now and the remainder expected to become effective in the second quarter of 2026.

This change is driven by upgrades made to the water system infrastructure since Washington Water acquired the Stroh’s system in late 2022 along with increased operating costs. Among significant investments made in the Stroh’s service area are:

• Replacement of a well pump, a motor, and two booster pumps to help increase pressure reliability.
• Installation of a new water quality sampling station.
• Safety improvements made to water storage tanks.
• Replacement of two wellhead meters designed to accurately record production data for the Department of Ecology and Department of Health.

“We are committed to providing quality, service, and value to our Stroh’s water system customers, and one important part of fulfilling this promise is by improving and maintaining the local water system infrastructure,” said Marty Kropelnicki, Group Chairman and CEO. “We believe these upgrades will help us continue to provide safe, clean, reliable drinking water to Stroh’s customers for years to come.”

New rates were effective as of May 23, 2025.
