(a) The sizes, types and kinds of fittings, couplings, pipes, unions, tees, gate valves and other appurtenances used in water main extensions shall conform to the specifications approved by the Water Superintendent as per AWWA standards.
(b) The ground shall be excavated in open trenches or in tunnels, if specified by the Water Superintendent, to a depth necessary to secure four feet of cover. The bottom of the trench shall not be less than four feet below the existing ground level in the street, unless otherwise authorized by the Manager.
(c) No person shall make open cuts on any street for the installation of lines, unless authorized by the Water Superintendent. If such authorization is not given, the line shall be tunneled under the street as specified in division (b) of this section. Bond must be secured to insure street repair to previous condition.
(d) All lines and fittings shall be inspected under the direction of the Manager. After all lines have been laid and fittings tightened, a test of the lines at adequate pressure shall be made, with full inspection for defects and leaks. Any defects shall be corrected by the installer and another test of the lines shall be made.
(e) After the final test and inspection of the lines have been made and such lines are found to comply with the requirements set forth by the Mayor and Council, the installer shall backfill the trenches and other openings for the mains or lines, and shall leave the ground surface in the same condition as it was before such installation.
