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.[1]

Capacity requirements and design details described in Sections
2.04.B. through 2.04.D.[1] 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).[1]
A.
Installation of a manhole.
B.
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.
C.
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.
