(b) In the event that a sewer service exists from the main sewer to a point outside of the street, the contractor shall excavate and expose the upper end of the service pipe. The elevation of the pipe leaving the structure shall be determined, and the difference between the two (2) pipes shall be sufficient so that a minimum grade of one - eighth inch (1/8 ") per foot is maintained. (3) Alignment. No connecting sewer shall contain bends or a combination of bends which at any point shall be greater than 45 degrees, and no more than two bends, regardless of angle, shall be permitted in any single house connection, except where manholes are constructed at such points and in such manner as directed by the Public Works Director. No connecting sewer shall be laid parallel to any bearing wall or footing unless further distance than three (3) feet from any such bearing wall or footing. No connecting sewer shall be laid within twenty (20) feet of any well. (4) Trenching and Backfilling. (a) All excavations shall be open- trench work unless otherwise authorized by the City_Engineer. The foundation in the trench shall be formed to prevent any subsequent settlement of the pipes. If the foundation is good and firm earth, the earth shall be pared or molded to give a full support to the lower third of each pipe. Bell holes shall be dug to provide ample space for pouring of joints. Care must be exercised in backfilling below the center line of the pipe in order to give it proper support. (b) Backfilling shall be placed in layers and solidly tamped or packed up to two (2) feet above the pipe. Backfilling shall not be done until the section to be backfilled has been inspected and approved by the Public Works Director. (5) Use of Existing Sewers. Existing sewer services or portions of such sewers may be approved for use by the Public Works Director. The Public Works Director may request that the old sewer be excavated for the purpose of facilitating inspection.

Where a sewer is laid across or over any existing cesspool or septic tank, only material approved by the Public Works Director shall be used for that portion of the connecting sewer which is laid across or over the existing cesspool or septic tank. (6) Connections at "Y" Only. Every connecting sewer shall be connected to the Municipal sewer system at the "Y" designated for the property served by the connection, except where otherwise expressly authorized by the Public Works Director.
