Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly. Spokane states that customers receive a monthly bill for water, sewer, and refuse, with usage-based water consumption and monthly service/capital charges.
- Rate structure
- Increasing block water-consumption tiers measured in units of 100 cubic feet, approximately 748 gallons. For 2026 inside-city residential accounts, water service is $20.07 monthly, water-wastewater capital is $36.30 monthly, and usage is $0.3775 per unit for the first 6 units, $0.7988 for 6–12, $1.0746 for 12–25, $1.6989 for 25–45, and $2.4436 above 45 units.
- Residential cost reference
- Approximately $114.61 at 5,000 gallons before refuse, stormwater, taxes, and any low-use wastewater credit: 5,000 gallons is about 6.68 units, producing roughly $2.52 of first-tier water use plus $20.07 water service, $36.30 capital, and $39.79 wastewater. Actual sewer and capital charges vary by account and service area.
- Wastewater and sewer calculation
- Spokane bases residential wastewater on fresh-water use during the most recent four-month winter billing cycle, typically December through March, so summer irrigation does not inflate sewer charges. The 2026 residential wastewater charge is $39.79 monthly plus $6.34 per unit/CCF of winter water use. Some low-water-use single-family customers receive a $10 monthly wastewater discount, up to $120 annually, under the city’s low-use program.
