Granite Falls
Granite Falls itself is a small town — about 4,500 people (2020 Census: 4,450) — with a city sewer system and a new $34 million treatment plant, completed in February 2026. But the large Granite Falls mailing area in the Pilchuck and Stillaguamish foothills is unincorporated county, outside the Urban Growth Area, and on septic. That is the area this page is for.
We serve the unsewered parts of the Granite Falls area: outside city limits, including the Mountain Loop Highway corridor, Gun Club Road, Jordan Road, and the foothill properties east and north of town. We do not target the in-town grid around Granite Avenue and Pioneer Street. Note: the city's sewer moratorium, in place since April 2018, was lifted on February 1, 2026, when the new $34 million treatment plant reached substantial completion — so new sewer hookups in town are allowed again, and in-town homes are generally on city sewer. The foothill properties outside the city limits are not affected by that change and remain on septic.

FAQ
Is my Granite Falls home on septic or sewer?

How often should a septic tank be pumped in the Granite Falls foothills?
As a general guide, every 3–5 years, depending on household size and tank size. Foothill properties with larger lots and older systems are worth checking on schedule rather than waiting for a problem.
