(a) Sanitary Sewers: All service connections for sanitary sewers shall be installed in accordance with the recommended practice for installing clay sewer pipe as provided for in the American Society for Testing Materials (ASTM) Specification C 12-64, as amended or for installing polyvinyl chloride (PVC) pipe as provided for in the "Uni-Bell Handbook of PVC Pipe." The pipe comprising the connection shall be laid at a minimum depth of four feet and a maximum depth of twenty-one feet below the finished ground surface. The pipe shall be bedded upon a granular foundation course consisting of uniformly graded one-fourth inch to one-half inch crushed gravel or stone for a minimum of six inch depth beneath the pipe. The connection pipe shall be laid with the bell ends upstream and the pipe shall be so bedded in the foundation course as to provide a uniform bearing along the entire barrel of the sewer and 120 degrees of its periphery. Under no circumstances shall the service connection be covered prior to inspection by the City Engineer or his or her duly authorized representative. Sanitary sewer service connections within public roadways or rights-of-way shall be laid in open cut trench as specified in this section, except as may be otherwise provided herein. Excavated earth and other materials removed from within the public roadway or right of way shall be removed from the site immediately upon excavation and promptly disposed of by the permittee. Backfill within the public right of way to the underside of the pavement and to within the 1:1 zone of influence of the roadway shall consist of thoroughly compacted premium crushed limestone or recycled Portland Cement Concrete (RPCC) meeting requirements of ODOT 304 limestone. Where no pavement exists the last three feet not under the pavement shall be original soil backfill. Repaving and reconditioning of all disturbed surfaces, including replacement of topsoil and reseeding, shall be done immediately upon completion of backfill. Permittee shall comply with the requirements of Chapter 1020.
