Sanitary Sewer

Side Sewers

The side sewer is the sewer pipe that connects a building to the sewer main located in the street. Property owners are responsible for maintenance and repair of side sewers. The City is responsible for sewer mains if they are located in public rights of way, like streets, or a utility easement dedicated to the City.


Homeowners are responsible for sewer backup problems on personal or private property. If there is any issue with a backup on city property or with a City of Anacortes sewer manhole, please call Public Works Operations immediately at 360-293-1921, if during normal business hours.


The Public Works Operations Sewer Division routinely maintains the sanitary sewer mains to keep them flowing freely. Our crews inspect and clean the sanitary sewer mains on a scheduled basis, but there are do's and don'ts that you can follow to keep your home’s sewer system as well as the City’s sewer system trouble-free.

Wise use of the sewage system and performance of simple preventive maintenance will help safeguard the system and reduce costs for everyone.
