sewer saddle(B.F.O.).
2-The correct saddle for a collector line of 6" plastic is a Smith Blair 313-
00066-314-000 6" x 2" saddle.
3-To connect a storm line to a concrete pipe, use a saddle made with a cast
iron hub. The pipe will extend from the hub to the face of the pipe. Cement mortar and oakum will
be used for a water and root-proof connection to the storm sewer.
23
1506 No Connection Available. If a storm sewer or collector line does not exist
in the roadway fronting the property, the discharge line shall be terminated at the back of curb. In the
event the storm sewer/collector line is on the opposite side of the pavement, the discharge line shall
be extended across the street. Back-of-curb discharges shall be directed downward to the pavement
by use of an elbow or other approved arrangement. The City of Ames shall be responsible for the
connection to the storm sewer/collector line for those services properly terminated at back-of-curb.
