Sewer / Water / Stormwater

Sewer Service

The City currently provides sewer service only within the city limits with approximately 2,900 commercial and residentail accounts and maintains 38 miles of sewer collection pipe, five lift stations, and a Membrane Bioreactor Wastewater Treatment Plant (WWTP). The monthly sewer utility rate is for the collection and treatment of sanitary sewer flow. Collection refers to the is the piped network, including pump stations, from the customer to the WWTP. Treatment at the plant converts sanitary sewer flow into clean water that is then discharged into the Snoqualmie River. Solids (biomass) which are a biproduct of the treatment process are collected and hauled off to an approved disposal facility.
