Sewer systems are made of an intricate network of drains and pipes that transport sewage and stormwater to wastewater treatment facilities. Sewer connections link individual sanitary service lines to the larger municipal sewer system.
New York City is a sprawling metropolis with sewer challenges related to the city’s populous urban environment and the system’s age and scale. Learn about three types of sewer connections used in NYC.
1. Spur Connection
Spur connections, also called house connections, are the most common type of residential sewer connections used in NYC. This is the most cost-effective connection type because it requires less labor.
Spur connections directly link individual properties to the main sewer line located underneath streets and sidewalks. They have a wye fitting—a Y-shaped device that allows one pipe to join another. The spur connection is inserted in the city sewer line, and a plug is left in the outlet. When it’s time to link a new sewage connection, a plumber removes the outlet plug.
2. Curb Connection
Another type of sewer connection used in NYC is a curb connection. The curb connection is located under the curb line, where the sidewalk and paved roadway meet.
Curb connections can be constructed for a new public sewer or after a building has been demolished. After a building is demolished, the sewer connection is plugged at the curb line. Often, a newly erected building can reconnect to the existing sewer line with a curb connection.
3. Fold-In Connection
Finally, when the city sewer line is only one size larger than the required connecting size, a licensed sewer contractor can install a fold-in connection. The contractor removes sections of the public sewer line and inserts a wye fitting.
If the new pipe is clay, the contractor caulks the joints. Finally, the contractor encases the exposed sewer line in ready-mix concrete.
