Wastewater and sewer calculation
Renton bills a $34.34 single-family wastewater charge plus a $62.66 King County sewage-treatment pass-through charge in 2026. The City describes the wastewater charge as a monthly base/utility rate and separately identifies the King County capacity/treatment component; the reviewed 2026 brochure does not use a winter-average formula for the standard single-family account.
Meter and infrastructure notes
The 2026 brochure identifies approximately 17,931 metered water connections and monthly billing, but the reviewed public pages do not identify whether the fleet is AMR/AMI or specify a universal read date. Customers can review usage through the City portal and contact Utility Billing with meter-read questions.
