(A) At any point in a main sewer or trunk line sewer where it is necessary to provide new sewage service, no vitrified clay Y or T saddle will be permitted. Entrance into the main sewer or trunk sewer will be constructed in the following manner: By first cutting the entrance to the main sewer or trunk sewer and then inserting a short piece of cast-iron pipe, four inches or six inches in diameter with a bell on one end, into the entrance in such a manner so as not to protrude beyond the inside face of the trunk or main sewer. The connecting pipe shall be so placed as to project upward at an angle of approximately 45 degrees from the horizontal and in addition shall be so placed to so direct the flow of the house connection sewage down stream into the main or trunk sewer. The only method by which a connection shall be made into the top of the main or trunk sewer is if the connection is constructed in accordance with the standard plan of the city entitled “Standard Chimney Pipe” and in accordance with the aforementioned connection method. It is hereby further stipulated that all Y connections or saddles shall conform to the standard plan of the city entitled “Standard Saddle Connection.”
(B) After the short section of connecting pipe is in place, an imbedment of cement concrete shall be placed under and around the main line sewer pipe and connecting pipe as required for a standard chimney pipe in accordance with the standard plan on file in the office of the Director of Public Works. The inside of the main or trunk sewer shall be checked to see that there is no protruding cement at the joint between pipe and saddle.
