All service connections shall be installed in accordance with the recommended practice for installing clay sewer pipe as provided for in the ASTM specification C 12-64 and subsequent amendments thereto. 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 finish ground surface. The pipe shall be bedded upon a granular foundation course consisting of uniformly graded one-quarter inch to one-half inch crushed gravel or stone, having a depth of at least four inches upon the subgrade. 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 uniform bearing along the entire barrel of the sewer and 120 degrees of its periphery. The connecting sewer outside of the public right of way shall be covered to a depth of at least six inches with compacted sand before native earth backfilling is commenced. Under no circumstances shall the service connection be covered prior to inspection by the Commissioner of Buildings. Sanitary sewer service connections within a public roadway or right of way shall be laid in open cut as specified in the foregoing, 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 or roadway shall consist of thoroughly compacted clean coarse sand. Repaving and reconditioning of all disturbed surfaces including replacement of topsoil and reseeding shall be done immediately upon completion of the backfill.
