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
- Bi-monthly for residential and non-residential customers. Bills are issued every two months and the 2026 rate changes appear on January 31 and February 28 billing cycles.
- Rate structure
- Meter-size bi-monthly base charge plus seasonal increasing block consumption rates per 100 cubic feet. For 2026, a 5/8-inch base is $44.91; winter rates are $2.97/$5.83/$7.35/$8.01 across increasing blocks, while summer conservation rates are $2.97/$7.00/$8.82/$9.62, with a 20% surcharge after 1,000 CCF in the summer schedule except irrigation.
- Residential cost reference
- Soos Creek's 2026 newsletter estimates about 0.99 cents per gallon for water and 0.50 cents for water treatment, with King County treatment adding about 1.1 cents, or roughly 2.6 cents per gallon from tap to treatment. At 6,000 gallons/month, that published average implies approximately $156/month combined, subject to the bi-monthly base, seasonal tier, and exact consumption allocation.
- Wastewater and sewer calculation
- The 2026 bi-monthly sewer charge is a $52.55 Soos Creek maintenance base plus a $3.50/CCF volume charge and a $125.32 King County treatment base plus $8.35/CCF. The volume charge applies to consumption above the first 1,500 cubic feet, and 100 cubic feet equals 748 gallons. Total bi-monthly sewer base is therefore $177.87 before excess volume.
- Meter reading
- Residential and most non-residential meters are radio-read and are read each billing period; Soos Creek states it does not estimate those meter readings. Bills are issued every two months, and InvoiceCloud/Water account tools provide payment history and paperless billing.
- Activation or transfer fee
- A first bill includes a one-time $16 administrative charge for change of ownership on an existing service location. Owners may request duplicate rental-property billing for an additional $2 per bill; the property owner remains responsible for the account.
