DRY CREEK WATER COMPANY LLC
Notice of Proposed Rate Adjustment
September 15, 2025
Dear Valued Customer,
Dry Creek Water Co. has submitted its first general rate case application as a regulated
utility to the Idaho Public Utilities Commission ("PUC"), requesting approval of a staggered
rate adjustment over a three year period.
This request represents an important milestone for our growing utility, as we seek to align
revenues with the actual cost of providing safe, reliable water service now and into the
future.
What This Would Mean for You
To ease the impact on our customers, Dry Creek Water Co. is proposing a phased
approach to rate increases, much like cost-of-living adjustments. These modest annual
increases are designed to keep pace with inflation and the rising costs of service, while
maintaining affordability for our customers.
Upon PUC approval, the monthly fixed fee and the usage fee will each increase by 6%, with
similar increases following in 2027 and 2028. The table below illustrates the impact on the
average monthly residential bill, currently $87.79, over the three-year implementation
period:
Year Monthly Fixed Usage Fee (per 1000 Average Monthly
Fee gallon unit) Bill
Current (2025) $47.50 $2.00 $87.79
Initial (2026) $50.35 $2.12 $93.06
2027 $53.35 $2.25 $98.68
2028 $56.50 $2.39 $104.65
Why an Adjustment Is Needed
This increase is necessary to:
• Keep pace with inflation and rising operation and maintenance costs;
• Manage the financial impacts that come with operating as a regulated utility; and
• Maintain compliance with environmental regulations.

Dry Creek Water Co. has historically prioritized keeping rates low for its customers.While this
approach has supported affordability in the early stages of service, it is no longer sustainable in
light of our growing responsibilities as a regulated utility. Dry Creek Water Co. remains firmly
committed to providing affordable service and maintaining high standards of customer service.
