Should I connect to city sewer or keep my septic system in Seattle?

If city sewer connection is available, compare the utility's current requirements with the permitted septic system's condition, maintenance needs, and property-specific terms.

This decision depends on the property's condition, the public utility's current connection rules, and the terms and obligations for both options. Review the utility's current connection requirements, septic abandonment rules, ongoing utility terms, and the likely maintenance or replacement scope of the existing system. Charges and rules vary by municipality, so use the applicable utility's current guidance rather than a regional estimate.

Connection may deserve evaluation when public sewer is available, the existing system needs major work, or local rules require connection. Keeping a septic system may remain practical when it is permitted and not subject to a mandatory connection rule. Confirm the parcel-specific answer with the local utility, county health authority, General Septic, and any other professionals whose role the property requires before making a decision.
