No. The homeowner is responsible for any sewer problems in the sanitary sewer system from inside the home to the point at which the sewer pipe joins the City's portion of the system, which is typically found in the street in front of a home or building or in the out lawn area. The City is responsible for the collection system that runs throughout the city. The City's portion of the collection system is comprised of pipes that are called "mains". These mains can be up to 48 inches in diameter. In contrast, some home or building pipes (also called laterals) are either 4 or 6 inches in diameter.
