Service connection

A service connection is the section that links a main pipe or sewer to a customer's internal installation, such as a building or plot. In sewer systems it usually connects to a manhole or directly to the main sewer with a tee or insert. On a longitudinal profile it appears as a branch with its own connection invert, slope and length. The connection invert must match the geometry of the main sewer. During review, check the slope direction, depth near the building and possible conflicts with other utilities.
