Provider briefing
How this utility’s billing works
Soos Creek Water and Sewer District operates as a public water authority serving Renton, Kent, Maple Valley, and Soos Creek Water & Sewer District service area. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as 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.. Bills are generated 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., and a typical residential cost reference is 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.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
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 and infrastructure notes
