Sewer Extensions

A sewer extension is an addition to the public sewer. If your property has a nonconforming sewer connection but doesn't have direct access to a public sewer, a sewer extension can allow you to connect your property directly to the public sewer.

Either the city or the property owner can construct a sewer extension. The city schedules sewer extension projects based on available resources and the capital improvement project schedule.

If you seek a sewer extension that is not part of the city's capital improvement schedule and no other resources are available, construction of the extension may become your responsibility.

Contact city staff for more information about sewer extensions and evaluating your property.
