Peak Water Rates in Effect

Peak residential water rates are in effect from May 16 through September 15 each year. Peak rates incorporate a three-tiered rate structure with progressively higher rates as water consumption increases. During warmer month, we depend on water stored in our mountain reservoirs to meet customer demand while leaving enough water in the rivers for fish. Peak water rates encourage customers to use water wisely.
