A "sanitary sewer service line," for the purposes of these standards, is defined as a sewer pipe designed to receive flow from a single building, extending from the sewer main or lateral to the building.
Minimum diameter of sanitary sewer service lines is six inches. If the service line is larger than six-inch diameter, a manhole shall be constructed at the point of its connection with the sewer main or lateral. Allowable service material is as shown in Section 2.04.C.
Capacity requirements and design details described in Sections 2.04.B. through 2.04.D. for sanitary sewers shall apply to sanitary sewer service lines, except the minimum slope shall be 0.60% for six-inch-diameter pipe and 1.20% for four-inch-diameter pipe.
In those instances when the service line is not immediately connected to the building to be served, it shall be tightly plugged, using a manufactured plug held firmly in place.
When sanitary sewer service lines are constructed as part of the same project as the sewer main or lateral, they shall be connected to the sewer main or lateral using a wye. When a sanitary sewer service line is to connect to an exiting sewer main or lateral, or where specific approval has been granted by the City Engineer for the construction of a service line after the completion of the sewer main or lateral, the connection shall be made by one of the methods detailed below or as provided in Section 8.6(2).
Installation of a manhole.
Circular saw cut of sewer main by proper tools, and proper installation of a hub wye saddle or a hub tee saddle, in accordance with manufacturer's recommendations.
Using the pipe cutter, neatly and accurately cut out desired length of pipe for insertion of proper fittings. Use Band-Seal® couplings, or similar couplings, and shear rings and clamps to fasten the inserted fitting and hold it firmly in place. Follow manufacturer's recommendations for the installation. Cement joints are prohibited.
