Utility rates and providers in Walla Walla County, Washington

Inside the city of Walla Walla, residential service is Pacific Power Schedule 16. As of the Washington price summary covering riders in effect on September 30, 2026, a single-phase single-family home pays an $8.50 basic charge, a combined effective energy rate of 14.311 cents per kWh, and a $3.79 Schedule 91 low-income assistance surcharge unless the customer is on discounted Schedule 17. At 1,000 kWh that is $155.40. Schedule 98, a 1.217 cent credit labeled as not applying to every customer, is left off that figure. The Schedule 16 sheet by itself is only 10.623 cents plus $8.50; the price summary is what adds the current riders.

Much of the county outside Pacific Power territory is Columbia Rural Electric Association, based in Walla Walla. The co-op said an average 3 percent increase took effect January 1, 2026, driven by Bonneville Power Administration wholesale costs. That notice did not publish a new customer charge or cents-per-kWh figure. The last dollar schedule the co-op posted in a rate notice was the January 2024 single-residential energy charge of 9.10 cents per kWh, a facilities-charge increase of $5 (the new total was not stated), and a demand charge of $1.75 per kW above 7 kW. Those 2024 dollars are not a 2026 bill, so this page does not estimate a Columbia REA total.

College Place addresses can be Pacific Power or Columbia REA. Check the bill header rather than the city limit.

City of Walla Walla water, effective January 1, 2026, is $41.30 a month for a 3/4-inch meter plus $4.201 per 1,000 gallons inside city limits. At a steady 5,000 gallons the charge is $41.30 plus $21.005, which the city comparison shows as $62.30. The sample line of $44.93 on the same page is for 1,500 cubic feet, about 11,221 gallons, not the 5,000-gallon comparison. The city says the posted water charge includes a 15.6% utility excise tax in 2026.

Unincorporated homes are often on private wells. The county does not run a retail water utility. Some addresses buy city water outside the limits; those outside-city rates are not on the inside-city table.

College Place still publishes 2025 residential bases on its utility page: water base $44.05 and then $1.81 per 1,000 gallons, plus a 10% utility tax on the water and sewer total. No 2026 College Place schedule was posted on that page as of September 30, 2026, so those 2025 dollars are not treated as the current bill.

Inside Walla Walla, residential wastewater effective January 1, 2026 is $67.40 a month and includes the first 6,000 gallons of metered water. At 5,000 gallons there is no extra volume charge. Use above 6,000 gallons is $7.147 per 1,000 gallons. Multi-family is $40.40 per unit. The 15.6% utility excise tax disclosure applies to this charge as well.

There is no countywide sewer system. Most unincorporated houses use septic tanks. College Place bills its own sewer. Its page still lists a 2025 base of $53.45, which includes 3,000 gallons, then $5.11 per 1,000 gallons, and says winter averaging (December through February) caps sewer flow from March through November. That 2025 schedule is not used here as a 2026 rate.

City sanitation, effective January 1, 2026, is $29.95 a month for a 96-gallon cart picked up weekly, or $22.94 for a 64-gallon cart. Recycling every other week is a separate $8.54. The average-bill table on the same page still shows recycling at $8.15; the recycling section dated January 1, 2026 is $8.54. Optional green waste is $26.15. The city landfill on Sudbury Road charges self-haul garbage $17.99 for loads under 300 pounds or $119.40 a ton, plus the 3.6% Washington refuse tax the city lists on disposal fees.

Outside the city, Basin Disposal of Walla Walla (UTC permit G-165, Tariff 15) bills curbside garbage. The January 1, 2026 residential item lists a 96-gallon cart at $33.12 a month for weekly garbage, a 64-gallon cart at $25.96, and a 32-gallon cart at $19.65. That item's recycling notes are marked n/a, so recycling is not folded into the $33.12. Washington Utilities and Transportation Commission docket TG-250902 approved the January 1, 2026 disposal-fee pass-through. College Place lists Basin Disposal, not city carts, for garbage.
