Marysville

Marysville runs its own sewer utility, and most of the city is sewered — but the unincorporated north and east of the city, and older homes more than 200 feet from a sewer main, are still on septic. If your home is in the Getchell or Sunnyside areas, or on the rural roads north toward Arlington, septic is the service you need.

We serve the unsewered parts of the Marysville area: unincorporated north and east Marysville, including Getchell, the Sunnyside and Quilceda Creek watershed, the 51st Ave NE and 67th Ave NE corridors, and the rural fringe north toward Arlington, plus older homes more than 200 feet from a sewer main. We do not target downtown Marysville, the Smokey Point and Cascade Industrial areas, or newer in-city subdivisions. Note: Marysville's sewer collection system maintains about 240 miles of sewer lines, serving more than 22,000 customers (City of Marysville, 2026 sewer rates). City code (MMC 14.01.050) requires connection to sewer when a septic system fails and a sewer line is within 200 feet of the structure — and can require extension beyond 200 feet unless an exception applies — so whether a specific home is on septic or sewer should be checked per parcel.
