Sewer Laterals

Sewer laterals are connections in sewer pipeline construction that are common whenever installing new pipe or improving current sewer pipeline systems for both public and private construction projects. Sewer lateral connections are the actual material and methods used to join a sewer line coming from a private property (sewer lateral) to the public sewer main line. Three most common sewer lateral connections are wye connection, saddle connection, and cut-in-wye connection.

The most common type of sewer lateral connections to sewer main pipelines are wye connections. Wye sewer lateral connections are manufactured in the shape of the alphabet letter "y". This type of connection is installed whenever there is a new sewer pipeline installation requiring new sewer laterals to individual properties. Unlike pressurized water pipeline systems, sewer and storm drainage systems are designed using gravity flow wherever possible. The "y" shape is more favorable to the gravitational flow pattern of sewer systems by directing flow of sewage into the same direction as the flow in the public sewer main line. Therefore, sewer main lines are less likely to have any clogs or backup. ye connections are made by attaching wye material to the ends of sewer main line pipe as the main line is being installed. Wye connections are installed at designed and required locations for the new laterals. Sewer wye connections are available in various types of material including polyvinyl chloride (PVC) and vitrified clay pipe (VCP) material, but typically, these sewer lateral wye materials are made of the same material as the sewer main line (i.e. a VCP sewer main will have a VCP material wye sewer lateral connection as well).
