(B) All types of pipe shall be handled in such manner as will prevent damage to the pipe or coating. The pipe and fitting shall be inspected by the subdivider for defects while suspended above grade. Accidental damage to pipe or coating shall be repaired to the satisfaction of the developer’s engineer or be removed from the job. Methods of handling shall be corrected to prevent further damage when called to the attention of the subdivider.
(C) Dirt or other foreign material shall be prevented from entering the pipe or pipe joint during handling or laying operations and any pipe or fitting that has been installed with dirt or foreign material in it shall be removed, cleaned, and relaid. At times when pipe laying is not in progress, the open ends of the pipe shall be closed by a water-tight plug or by other means authorized by the developer’s engineer to ensure absolute cleanliness inside the pipe. Threaded pipe ends shall be protected by couplings or other means until laid.
(D) The watermains shall be laid and maintained to lines and grades established by the drawings and specifications, with fittings, valves, tapped, or bossed outlets, and hydrants at the required locations. Valve-operating stems shall be oriented in a manner to allow proper operation. Hydrants shall be installed plumb.
(E) All watermains shall be laid to a minimum cover depth of four feet, six inches. Depth shall be varied as necessary to accommodate crossings with other utilities. Record depth measurements shall be taken at intervals not greater than 100 feet to verify installed depth. Depth shall be determined to proposed finished grade.
(F) Record horizontal or vertical locations of all watermains shall be provided at intervals not greater than 250 feet to verify installed location. Long radius curves, either horizontal or vertical, may be laid with standard pipe by deflections at the joints for most rigid pipes and in the pipe for most flexible pipes. If shorter lengths are required, the drawings will indicate maximum lengths that can be used.
(G) Where field conditions require deflection of curves not anticipated by the drawings, the developer’s engineer will determine the methods to be used. Maximum deflections at pipe joints and laying radius for the various pipe lengths shall be as recommended by the pipe manufacturer or stated in applicable AWWA Standards. When rubber gasketing pipe is laid on a curve, the pipe shall be jointed in a straight alignment and then deflected to the curved alignment. Trenches shall be made wider on curves for this purpose.
(H) The trench bottom shall be true and even to provide support for the full length of the pipe barrel. The pipe shall be bedded in a minimum of four inches of pipe bedding. Holes for the bells shall be provided at each joint, but shall be no larger than necessary to allow joint assembly and to ensure that the pipe barrel will lie flat on the trench bottom. Pipe shall be installed in accordance with AWWA Standard C600.
(I) Maximum joint deflection angle for any watermain shall be three degrees.
(K) A valve box shall be provided for every valve. The valve box shall not transmit shock or stress to the valve. The valve box shall be centered over the operating nut of the valve, with the box cover flush with the finished surface. Valve boxes shall be set true vertically and supported to remain so until all backfill has been placed.
(L) (1) All hydrants shall stand plumb and shall have their hose nozzles parallel with the length of the street, with pumper nozzle (four and one-half inches) facing the street. Hydrants shall be set with the bottom flange of the top section two inches above ultimate final grade of the ground, with a maximum deviation of two inches in elevation being allowed.
(2) Each hydrant shall be connected to the main with a six-inch or larger diameter branch controlled by an independent valve. The valve shall be restrained to allow shut-off when the hydrant is to be removed. All hydrants and hydrant leads shall have restrained joints from the main to the hydrant including the connection to the main and the hydrant foot.
(M) Drainage shall be provided at the base of the hydrant by placing coarse gravel from the bottom of the trench to at least six inches above the waste opening in the hydrant and to a distance of one foot around the elbow. The surface of the coarse gravel shall be covered with geotextile filter fabric to prevent soil intrusion into the stone. Adequate support must be provided to prevent the fire hydrant from settling. The bowl of each hydrant shall be well braced against a sufficient area of unexcavated earth at the end of the trench with concrete thrust blocks.
(N) New watermains and appurtenances shall be connected to the existing piping in accordance with the details shown on the drawings. If the existing piping can be isolated from the system, the connections shall be made by using cutting-in-sleeves in the existing piping. If the existing watermains cannot be isolated from the system, the connections shall be made under pressure using tapping sleeves and tapping valves.
(O) Where the connection of a new watermain or appurtenance requires interruption of service and notification of customers affected, the village’s maintenance superintendent and subdivider shall mutually agree upon a date and time for the connections to be made. The date and time will allow ample time for the subdivider to assemble the labor and materials and for the village to notify all customers affected.
