A. 
Gate valves shall be placed at all street intersections and in such locations that not more than 800 feet of main will have to be isolated in the event of a shutdown. Two copies of an as-built drawing showing the location of all valves, with ties, shall be furnished to the Town Clerk before the system will be accepted by the Town.
B. 
All gate valves shall conform to the latest AWWA Standard Specification C500. They shall be designed for a minimum cold water working pressure of 200 psi. Valves shall be of the parallel seat design using bronze seat and disc rings. All valves shall open counterclockwise, have O-ring packing and nonrising stems. Buried valves shall have a two-inch square wrench nut. Exposed valves shall have suitable hand wheels.
C. 
All buried valves shall be fitted with an adjustable cast iron valve box complete with cover. Boxes shall be of the sliding type. Boxes shall be of such length as will be adapted, without full extension, to the depth of cover required over the pipe at the valve location. The word "WATER" shall be cast in the cover.
A. 
Hydrants shall be placed so that all buildings within the water district will be within 600 feet of a hydrant. Hydrants shall also be placed at all intersections, at the high points of all mains and at each dead end in the distribution system. Hydrants shall be set so as to be readily accessible to the Fire Department and with the center of the nozzle outlets at least 18 inches above the ground and the pumper connection facing the street.
B. 
Hydrants shall be dry-barrel type conforming with AWWA C502 with breakaway features such that the hydrant valve will remain closed when the barrel is broken off. Hydrants shall be cast iron bodied, post-type hydrants having compression valves with a five-and-one-quarter-inch diameter minimum valve opening. The valve shall open counterclockwise. The operating nut and cap nuts are to be seven-eighths-inch square. Hydrants shall have two two-and-one-half-inch hose outlets, 3 1/16 inch O.D., 7 1/2 threads per inch, and one four-inch pumper connection, 4 7/8 inch O.D., six threads per inch.
C. 
Each hydrant shall be connected to the main with six-inch diameter pipe and shall have a six-inch gate valve with an adjustable valve box and cover between the hydrant and the main. Hydrants shall be bedded in and surrounded with crushed stone or crushed gravel. Hydrants shall be painted with one coat of zinc chromate primer and two finishing coats of yellow hydrant enamel.
Each property shall have an individual water service connection. The service connection shall consist of a corporation stop at the main, Type K copper tubing having a minimum diameter of 3/4 inch, and a curb stop with an adjustable valve box at a point located on or as near as possible to the right-of-way line. All service shutoffs shall be accurately located, and two copies of an as-built drawing showing their location, with ties, shall be furnished the Town Clerk before the system will be accepted by the Town.
A. 
All tees, bends of 1/16 or greater, hydrants and valve and fitting clusters shall be secured using tie rods or anchoring couplings. Concrete thrust blocks shall be installed behind all tees, bends of 1/16 or greater and hydrants in addition to anchoring fittings.
B. 
Temporary thrust blocks shall be provided at all plugs or other points of future connection. In addition, tie rods shall be placed through the plug and connected to a clamp secured to the pipe barrel. In lieu of the rods, mechanical joint retainer glands may be used.
C. 
Tie rods shall be of adequate diameter and painted with a suitable bituminous base material.
D. 
Concrete for thrust blocks shall be placed against undisturbed soil only and shall provide adequate bearing area against the side of the trench.
A. 
All ductile iron pipe shall be laid in accordance with AWWA C600 (latest issue). All ductile iron pipe shall be laid on a four-inch depth (minimum) bed of crushed stone, peastone, or crushed gravel (three-fourths-inch maximum size) properly prepared to furnish uniform bearing along the barrel of the pipe. Ductile iron pipe shall be backfilled to a minimum depth of six inches over the top of the pipe with the crushed bedding material.
B. 
Great care shall be taken during construction to minimize the possibility of dirt, debris or animal life entering the pipe. Stones, leaves, and all other debris shall be removed from the pipe before it is lowered into the trench. Any open ends shall be fitted with a tight plug to prevent dirt, debris and/or groundwater from entering the main whenever the project is left unattended.
Each section of line will be subjected to hydrostatic tests. Contractor shall furnish all equipment and connections to perform these tests. Whenever practical, these tests shall be conducted prior to backfilling the trench. Testing procedures, allowable leakage, etc., shall be in accordance with Section 4: Hydrostatic Tests, as contained in AWWA Standard C 600 (latest issue). The test pressure shall be 150 pounds per square inch, unless indicated otherwise on the drawings. Any leaks disclosed during testing shall be located and repaired by the contractor at his expense.

C. 
After the main is flushed with potable water, the subdivider shall demonstrate via water analysis that the disinfection procedure has been successful. Copies of the water analyses shall be made available to the Broome County Health Department and the Town Clerk.
Booster pumping stations, storage facilities and other appurtenances to the distribution system shall be designed and constructed to afford a maximum of public safety, dependability and efficiency in operation and maintenance. Two copies of as-built drawings of these facilities, together with all manuals and descriptive data, shall be furnished the Town Clerk before the facilities will be accepted by the Town.
