Snohomish County, WA
Arlington
Arlington's city core is sewered — the city runs a secondary-treatment plant on the Stillaguamish River with about 50 miles of sewer piping — but the rural ring around the city is on septic. East toward Oso and the Stillaguamish valley, north toward the Skagit County line, and around the airport, homes are outside the sewer service area.
We serve the unincorporated Arlington area: the rural ring outside the city and its Urban Growth Area, including the Stillaguamish valley east of the city toward Oso, the 67th Ave NE and 172nd St NE corridors, the area north toward the Skagit County line, and the area around the airport — where the city only recently agreed to explore extending sewer and water to a tribal casino and hotel, which implies that area is not currently sewered. We do not target the in-city core.
