What is the average cost for installing a sewer connection?

As of 2015, the average cost of installing a sewer connection ranges from $1,500 to more than $50,000 depending on the location of the connection. The installation cost includes both the fees from the sewer agency and the price charged by a contractor or plumber.

When installing a sewer connection, additional fees, such as permit fees or ongoing sewer usage fees, may increase the total cost of the project. Usage fees can range from $600 to more than $800 each year. The cost may depend on the number of gallons that go through the system, and a homeowner may pay monthly, quarterly or semi-annually depending on the municipality.
