(a) Sewer laterals shall not be less than six inches in diameter. All joints shall be watertight.
(1) Sewer laterals from the main to the owner's residence shall be of the following material:
A. PVC sewer pipe manufactured in accordance with the most current revision of ASTM Designation D 3034 (SDR 35) or approved equal as determined by the Director of Public Service or his or her designee.
(2) The appropriate Fernco flexible coupling or approved equivalent 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 sewer connection constructed of a six-inch minimum SDR 35 bell and spigot pipe with a gasket, or approved equal as determined by the Director of Public Service or his or her designee, which shall extend from the main sewer to within five feet of the building, at which point a Fernco transition fitting or approved equal as determined by the Director of Public Service or his or her designee, shall be installed and connected to Schedule 40 pipe. Glued fittings are not permitted. A cleanout shall be installed on the sewer lateral next to the outside wall or installed inside the structure flush with the finished 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) 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 main 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 flexible watertight coupling (Fernco or approved equal). The contractor is responsible for the installation of the sewer lateral and shall make arrangements with the City Building Inspector, the Superintendent of Service Department, or his or her designee to inspect the sewer tap upon the completion of the installation. 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. 57 or 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 ensure 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 Service Department or his or her designee.
(g) After the piping installation is approved by the Superintendent of Service Department or his or her designee, it shall be backfilled to a depth of at least six inches above the top of the pipe with 57 or 67 size limestone conforming to that specified for bedding material. This initial backfill shall be thoroughly tamped to the satisfaction of the Superintendent of Service Department or his or her designee with precaution taken so that no misalignment and no change in grade will occur during the backfilling operation. The balance of the trench located outside of pavement limits shall be backfilled with the excavated materials free of large stones or lumps of soil.
(h) All excavations within the limits of street pavement, alleys, parking areas or public drives shall be backfilled with gravel consisting of two feet of 57 size limestone, followed by a top coat of compacted 304 limestone to subgrade. Gravel backfill shall meet with the approval of the Superintendent of Service Department 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. The contractor shall be responsible for all the expenses accrued for the pavement replacement.
(i) All excavations shall be adequately guarded with barricades and lights to protect the public from hazard.
(j) Whenever possible, sewer laterals shall be installed ten feet apart from any other utility infrastructure; including water service lines, underground electric lines, natural gas lines, cable, fiber, and telecommunication lines.
(k) Whenever possible, any sewer lateral that crosses over or under other underground infrastructure shall be placed eighteen inches above or below the other infrastructure.
(l) Wherever a force sanitary sewer main is installed, the property owner connecting to the force main shall be responsible for their mechanical pump and sewer lateral up to and including the connection to the municipally owned sewer main.
