(a) House sewer laterals shall not be less than six inches in diameter. All joints shall be watertight.
(1) House sewer laterals from the main to the owner's residence shall be one of the following materials:
A. Vitrified sewer pipes meeting the latest issue of the requirements of the American Society for Testing Materials (ASTM) Designation C-700, with bell and spigot joints, including a compression-type gasket conforming to the material and testing requirements of ASTM Designation C-425;
B. PVC sewer pipe manufactured in accordance with the most current revision of ASTM Designation D 3034 (SDR 35); or
C. ABS plastic solid wall pipe, meeting the requirements of the most current revision of ASTM Designation D 2751.
(2) The appropriate Fernaco flexible coupling or approved equal adaptor shall be used to connect different pipe materials.
(b) Whenever possible, the house sewer lateral shall be brought to the building at an elevation below the basement floor. For each building there shall be a separate six-inch minimum sewer connection, which shall extend from the main sewer to within five feet of the building, at which point a Fernaco (or equal) transition fitting will be installed and connected to Schedule 40 pipe. Once inside a structure a cleanout will be installed flush with the finish floor.
(c) No building sewer lateral laid parallel to any bearing wall shall be installed within three feet of the wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The house sewer lateral shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipe and fittings.
(d) House sewer laterals shall have a minimum slope of one-eighth inch per foot laid to a straight line and grade. Connections to the public sewer shall be made at wye (or tee used if drop in from top only) fittings installed for this purpose. If a wye or tee fitting is not available, connection into the public sewer shall be made by using an approved manufactured watertight saddle or flexible watertight couplings (Fernaco or approved equal). The sewer digger shall make arrangements with the City Building Inspector to inspect the tap. Long radius bends shall be used, as required, at the wye or tee fittings. The pipe shall be laid on six inches of crushed stone bedding material conforming to size No. 67 of Table 703-1 of the State of Ohio Department of Transportation Construction and Material Specifications.
(e) After the bedding material is placed in the bottom of the trench, the pipe shall be laid in the bedding material with care being taken to insure that the bottom of the pipe is resting on the bedding material for its full length. The pipe shall then be adjusted to the proper elevation by adding or removing bedding material as required.
(f) No backfilling over completed work shall be done without the permission of the Superintendent of Wastewater Treatment and Sewers or the Director of Public Service or his or her designee.
(g) After the piping installation is approved by the Superintendent of Wastewater Treatment and Sewers or his or her designee, it shall be backfilled to a depth of at least six inches above the top of the pipe with granular material conforming to that specified for bedding material. This initial backfill shall be thoroughly tamped to the satisfaction of the Superintendent of Wastewater Treatment and Sewers or his or her designee with precaution taken so that no misalignment and no change in grade will occur during the backfilling operation.
(h) The balance of the trench located outside of pavement limits shall be backfilled with the excavated materials free of large stones or lumps. All excavations within the limits of street pavement, parking areas or public drives shall be backfilled with gravel backfill compacted in place. Gravel backfill shall meet with the approval of the Superintendent of Wastewater Treatment and Sewers or his or her designee prior to its installation. Pavement shall be replaced in accordance with Standard Drawing No. 2 on file in the office of the Director of Finance and Public Record. All excavations shall be adequately guarded with barricades and lights so as to protect the public from hazard.
