Director. <br />B. Joints and Connections: All joints and connections shall be constructed of materials <br />approved by the Public Works Director. <br />C. Grades: <br />1. Unless otherwise, all house sewers shall have a grade of not less than one-eighth inch <br />per foot. A grade of one-quarter inch per foot should be used wherever practical. The <br />contractor shall check grades before construction proceeds. Wherever possible, the <br />connecting sewer shall join the building at an elevation which is below the basement <br />floor of such building. (Ord. 219, 9-4-56) <br />2. In the event that a sewer service exists from the main sewer to a point outside of the <br />street, the contractor shall excavate and expose the upper end of the service pipe. The <br />elevation of the pipe leaving the structure shall be determined, and the difference <br />between the two pipes shall be sufficient so that a minimum grade of one-eighth inch <br />per foot is maintained. (1990 Code) <br />D. Alignment: No connecting sewer shall contain bends or a combination of bends which <br />at any point shall be greater than 45 degrees, and no more than two bends, regardless of <br />angle, shall be permitted in any single house connection except where manholes or, in <br />case of slab home, cleanouts are constructed at such points and in manner as directed by <br />the Public Works Director. No connecting sewer shall be laid parallel to any bearing <br />wall or footing unless further distant than three feet from any such bearing wall or <br />footing. No connecting sewer shall be laid within 20 feet of any existing well. (Ord. <br />234, 8-6-57) <br />E. Trenching and Backfilling: <br />1. All excavations shall be open trench work unless otherwise authorized by the City <br />Engineer. The foundation in the trench shall be formed to prevent any subsequent <br />settlement of the pipes. If the foundation is good and firm earth, the earth shall be pared <br />or molded to give a full support to the lower third of each pipe. Bell holes shall be dug <br />to provide ample space for pouring of joints. Care must be exercised in backfilling <br />below the center line of the pipe in order to give it proper support. <br />2. Backfilling shall be placed in layers and solidly tamped or packed up to two feet <br />above the pipe. Backfilling shall not be done until the section to be backfilled has been <br />inspected and approved by the Public Works Director. <br />F. Use of Existing Sewer Services: Existing sewer services or portions of such sewers may <br />be approved for use by the Public Works Director. The Public Works Director may <br />request that the old sewer be excavated for the purpose of facilitating inspection. No <br />cesspool or septic tank shall be connected to any portion of a house sewer that is also <br />laid across or over any existing cesspool or septic tank, the existing cesspool or septic <br />tank shall first be pumped clean and filled with earth to the surrounding ground level. <br />Where a sewer is laid across or over any existing cesspool or septic tank, only material <br />approved by the Public Works Director shall be used for that portion of the connecting <br />sewer which is laid across or over the existing cesspool or septic tank. <br />G. Connections at "Y" Only: Every connecting sewer shall be connected to the Municipal <br />sewer system at the "Y" designated for the property served by the connection, except <br />where otherwise expressly authorized by the Public Works Director. Where expressly <br />authorized by the Public Works Director, all connections made at points other than the <br />designated "Y" shall be made only under the direct supervision of the Public Works <br />Director in such manner as the Public Works Director may direct. <br />H. Sump pumps: <br />1. All new and existing structures with sumps for which a building permit is issued shall <br />be plumbed to the outside of the dwelling. All new structures shall be inspected by City <br />personnel before a certificate of occupancy is issued. A sump pump discharge system <br />shall not be connected directly or indirectly to the City's sanitary sewer system. A <br />sump pump shall have a permanently installed discharge line, which provides for year- <br />round discharge to the outside of a building or structure. The discharge line shall be <br />
