(A)   General. The materials of construction and general installation procedures, with the exception of fire hydrants, shall comply with the specific applicable standards set forth under §§ 53.15 through 53.17, §§ 53.35 through 53.38, as well as "Standard Details-Water Distribution Systems".
   (B)   Fire hydrants. Hydrants shall comply with AWWA Standard C502, "Fire Hydrants for Ordinary Water Works Service", and shall be equipped with a minimum of one pumper outlet nozzle 4-1/2 inches in diameter and two hose nozzles 2-1/2 inches in diameter. Threads, nozzle caps, operating nuts, and color shall conform to Lake Mary Standards. Units shall be traffic type with breakable safety clips, or flange, and stem, with safety coupling located below barrel break line to preclude valve opening. Outlet nozzles shall be on the same plane, with minimum distance of 18 inches from center of nozzles to ground line. Valve shall be compression type with 5-1/4 inches minimum opening and show inlet connection to be six inches minimum.
      (1)   Hydrants shall be installed plumb and in true alignment with the connection pipes to the water main. They shall be securely braced against the end of the trench (undisturbed soil) with concrete thrust blocks. The gravel or crushed stone for the drain sump, followed by backfilling, shall be carefully placed and compacted. Installed hydrants shall be painted fluorescent red for the final coat.
      (2)   Hydrant placement shall not be at a distance greater than 18 feet from a paved stabilized area which can withstand the weight of a Class A pumper. The center of the steamer port shall be 18 inches above final grade. Steamer port shall be correctly positioned for the proper connections.
      (3)   Hydrant valve shall be permanently connected to the water main tee with "All-Thread" or equal.
      (4)   A blue reflective hydrant marker shall be installed per DOT specifications for all fire hydrants.
   (C)   Joint restraining. Pressure piping, fittings, and other items requiring restraint, shall be braced with thrust blocks or other restraining assemblies. Said restraining devices shall be designed for the maximum pressure condition (testing) and the safe bearing loads for horizontal thrust, if thrust blocking is used.
   (D)   Pipe depth and protection. The standard minimum cover for water distribution systems shall be 30 inches from the top of the pipe to finish grade. However, should this design not be feasible, protective concrete slabs shall be provided over the pipe within the limits of the lesser cover. Where waterways, canals, ditches or other cuts are crossed, protective concrete slabs shall also be installed across and to ten feet each side of the bottom. Additionally, approved utility crossing signs shall be placed on the pipe alignment at each side of the canal and the like.
   (E)   Connections at structures. Where pipes are to extend into or through structures, flexible joints are to be provided at the wall face.
   (F)   Special exterior protection for corrosion. Extra protection shall be provided for underground cast or ductile iron pipe and fittings within areas of severe corrosive conditions. This shall be accomplished by the installation of polyethylene encasement, through the area of concern. The soil test evaluation to determine the necessity for extra protection in suspect areas shall be set forth in ANSI Standard A21.5. Additionally, where other existing utilities are known to be cathodically protected, case or ductile iron pipe crossing said utility shall be installed parallel to and within ten feet of; protection shall also be provided. Steel pipe shall not be installed in severe corrosion areas.
   (G)   Air venting and blow-offs. Where the water main profile is such that air pockets or entrapment could occur, resulting in the blockage, methods for air release shall be provided. Air venting capabilities shall be provided for distribution mains by appropriately placing fire hydrants, blow-offs, or other manual devices. At critical points on major mains, automatic air release assemblies shall be installed. Special care shall be taken to preclude any cross-connection possibility in the design of automatic air release valve application. All dead-end water mains, temporary or permanent, shall be equipped with a manually operated blow-off at the terminal.
   (H)   Service connections. Connections to water mains two inches and larger shall be made by drilling the appropriate size hold and installation of service saddle, with services to smaller sizes accomplished by in-line fittings. Water service lines from the main to the curb stop shall not have a minimum diameter of less than one inch for single services. Where main size and flows are appropriate double service will be of 1-1/2-inch polyethylene tubing wyed to 2 one-inch connections. Minimum tap size will be 1-7/16 inches. Wye will be located so as to be clear of paving level. Corporation stops will be used in all connection taps. A fitting with the service line extended into the tree lawn, perpendicular to said line, shall terminate with a plugged curb stop, pending meter installation. All curb stops shall be ball type and of one piece brass construction with locking provisions, and meter couplings manufactured to the stop as one piece. Meter connection branches will be used for double services and will be of one piece brass construction. A distance of 7 1/2 inches shall be required between meter connection branches. Tap size will be minimum 15/16 inch for all service connections. Flanged full circle stainless steel inserts will be used on all polyethylene compression connections.
