The work required under this section includes all cold water distribution lines, valves, hydrants, and related items including excavating and backfilling necessary to complete the work shown on the drawings. The ends of water service lines shall be tightly plugged or capped at the terminal points pending the connecting to all such lines of the building piping as specified in the plumbing specifications and architectural drawings. 2. MATERIALS: A. Cast Iron Pipe: Cast iron pipe shall meet AWWA Specification C -106 with push —on joints meeting AWWA Specification C -111. Wall thickness shall be determined from Table 6.4 in AWWA C -106. Ductile iron pipe shall meet AWWA C -150 and C -151 Specifications. Pipe to be cement lines per AWWA C -104. B. Copper Tubing: Shall be seamless, annealed copper tubing complying with Federal Specification WW —T -799. Fittings shall be wrought copper or cast bronze with solder joints. Solder shall be of a composition recommended by the manufacturer of the fittings. C. Fire Hydrants: Shall comply with AWWA Specification C -502 and shall meet local standards and requirements, particularly as to nozzle diameters and threads, direction of opening and dimensions of operating and cap nuts. Fire Hydrants shall have one pumper and two hose nozzles. A valve opening not less than 5 inches and a 6 inch inlet connection. The length of the hydrant barrel shall be determined by the specified depth of cover over the pipe. D. Valves: All valves and stops shall have ends suited or adapters shall be provided for the proper installation in the lines in which they are located. Valves shall meet local standards or in the absence of such standards, the following requirements: 1. Valves in cast iron pipe shall be iron body, bronze mounted, disc gate valves conforming to AWWA Specification C -500. They shall open in the some direction as those used in the local waterworks system. Valve stems shall terminate in 2 inch wrench nuts. Furnish two (2) keys. 2. Valves in copper pipe shall be standard brass body, round —way, ground —key stops with T heads. Furnish two (2) keys. E. Valve Boxes: Shall meet local standards or in the absence of such, shall comply with the following requirements: 1. For iron body valves, boxes shall be approved standard buffalo —type, cast iron, adjustable shaft boxes, having a minimum shaft diameter of 5 -1/4 inches. 2. For brass body valves (stops) boxes shall be approved standard cast iron extension service boxes, having a minimum diameter of 2 -1/2 inches and having lid held in place by a brass or bronze bolt. The castings shall be coated with two coats of coal —tar pitch varnish. Furnish two (2) keys for bolt in lids. F. Stops: Stop shall be those manufactured by Ford or Mueller Corporation with AWWA taper thread, and with copper compression type fitting on outlet, or equal. G. Blow —off Valves: Blow —off valves shall be those manufactured by Muller Corporation (H -10283 or H- 10291), or equal. H. Angle Valves: Angle valves at the end of water service stub are to be copper compression type fitting also, and are to be protected with plastic bag over the valve. I. Taps: 3/4 taps in lines smaller than 4 inches shall be only by tapped tee or tapping saddle. Water service lines should be marked on curbs with a stamped "W ", placed while pouring curbs. 3. APPLICATION: A. Permits and Codes: The intent of this section is the specifications if that the con!,-actor's bid on the work covered herein shall be based upon the drawings and specifications but that the work shall comply with all applicable codes and regulations. Contractor shall furnish all necessary bonds to get permits for cuts and connections. B. Existing Improvements: Maintain in operating condition all active utilities and sewer and other pipe system that may be encountered. C. Trenching: Lay all pipe in open trenches, except when local authority gives written permission for tunneling. Provide a separate trench for the water line at least 10 feet horizontally from any sanitary sewer. In locations where separate trenches for sewer and water lines are impracticable, lay the water pipe on a solid shelf at least 18 inches above the top of the sewer. D. Width of Trench: Excavate trenches minimum of pipe diameter plus 12 ". E. Sheeting and bracing: Sheet and brace trenches as necessary to protect workmen and adjacent structures. All trenching shall comply with the Occupational Safety and Health Administration Standards. F. Water Removal: Keep trenches free from water while construction therein is in progress. Under no circumstances lay pipe or appurtenances in standing water. Conduct the discharge from trench dewatering to drains or natural drainage channels. G. Grading Trench Bottoms: The bottom quadrant of the pipe shall be fully and uniformly supported. The full load shall rest on the barrel of the pipe. The trench may be excavated to a depth of 4 inches or more below final grade with sand, crushed stone or gravel backfill to bring it back to pipe laying grade. For a depth of at least 12 inches above the top of the pipe backfill with earth or granular material free from large stones, roots or frozen clogs. Tamp this backfill thoroughly taking care not to disturb the pipe. Backfill under walks, parking areas, driveways and streets with granular material only and tamp thoroughly, by approved methods. Trenches parallel to and within 10 feet of paved roadways shall be constructed the same. H. Tests: Before joints are covered, fill the piping with water, opening hydrants or at least two hours at a pressure of 100 pounds per square inch. Inspect all joints for leakage and remedy any leaks. Upon completion of the water distribution mains, flush out the system until the water runs clear. As soon as the system has been flushed out, it shall be sterilized in accordance with the requirements of City of Carmel. I. If a horizontal distance of 10 feet cannot be maintained between the water line and and a sanitary sewer line, one of the following shall be done. a. Water line laid in a separate trench and 18" above sewer. b. Water line laid in same trench on a bench of undisturbed earth and sewer at least 18" below bottom of water line. Where water lines and sewers cross and the water line cannot be placed above the sewer with a minimum of 18" vertical clearance, the sewer must be constructed of water works grade cast iron pipe with mechanical joints within 10 feet of the water line. J. Utilities: It shall be the responsibility of each contractor to verify all existing utilities and conditions pertaining to his phase of the work. It shall also be the contractors responsibility to contact the owners of the various utilities before work is started. The contractor shall notify in writing the owners or the engineer of any changes, errors or omissions found on these plans on in the field before work is started or resumed. K. New Water Main Construction: Contractor to record dimension of each water stub and valves from nearest fire hydrant measured along water main. The locations of hydrants and water valves, along with any other construction changes are to be incorporated on the original construction drawings and "Record Drawing" prints submitted to Engineer's Office as soon after completion of construction as possible.
