(A) General.
(1) No residential, commercial or industrial subdivision, site plan or planned development shall be approved unless it is served by the village's water supply system.
(2) In the case of any structures, whether residential, commercial or industrial, constructed prior to the adoption of this chapter and served by a private well system, the following shall apply:
(a) As soon as a village water main is contiguous to and available to serve a structure or building on a private well system, the owner must properly abandon the private well system and connect to the village's public water supply system within 1 year of the availability of the public water supply system. As used herein, a water main is contiguous to a building or structure if the main or the easement or right-of-way in which it is located is adjacent to, touches or runs across, through or under the lot, tract or parcel of land upon which the building or structure is located.
(b) All water supply systems which are installed in the public ways or easements shall be deemed to be dedicated to the village upon, the village's approval and acceptance of the public improvements, as evidenced by the action of the Village Board.
(B) Design. Water distribution mains shall be of adequate size and shall serve the entire development.
(1) Water mains shall be designed according to the "standard Specifications for Water and Sewer Main Construction in Illinois" or current EPA regulations.
(2) Installation.
(a) The mains shall, in general, be installed in the street right-of- way, but in no case shall mains be installed within 15 feet of a building.
(b) All water mains shall be installed with a minimum depth of cover of 4½ feet, measured from final grade to the top of the pipe.
(c) Mains shall be extended to the property line of the development along public rights-of- way and at any other location indicated by the Village Engineer.
(d) All excavation, backfilling, restoration of surfaces, and all related work shall be completed in accordance with this chapter.
(3) Size. The minimum size shall be 8 inches, internal diameter, in residential areas and 12 inches, internal diameter, in all other areas.
(4) Gridiron or looping of mains.
(a) Each 8-inch water main shall be looped (except cul-de-sacs or stubbed streets, unless deemed necessary by the Village Engineer) so that runs between connections to 8 inches or larger size mains shall not be greater than 1,200 feet.
(b) Each 10-inch water main shall be looped so that runs between connections to mains 10 inches or larger shall not be greater than 1,400 feet in a commercial area or 1,800 feet in residential areas.
(c) Each 12-inch water main shall be looped so that runs between connections to mains 12 inches or larger shall not be greater than 2,200 feet.
(d) If the design engineer's report shows spacing greater than the above for the required residual pressure, that spacing shall supersede the above requirements with the approval of the Village Engineer.
(5) Valves. Valves shall be located on water mains in such a manner to effectively isolate the sections from the system with minimum disruption.
(a) Valves shall be installed so that not over 500 feet of main will be shut off at any given time.
(b) If a tee is installed, 2 valves shall be used.
(c) The design engineer shall, by diagrams and/or written reports, set forth his or her basis for location of water main valves.
(d) No more than 15 single-family dwelling units shall be without water with the shutting off of any 3 valve locations.
(6) Valve boxes. Valve boxes shall be used on all main valves and auxiliary valves.
(a) Valve boxes shall have a base compatible with the size and type of valve to be operated and shall extend to finished grade ground level.
(b) Valve box covers shall be marked "WATER."
(7) Thrust blocks. Thrust blocks are required at all valves, hydrants, tees and bends.
(a) Engineering drawings shall indicate the location of each concrete thrust block to be installed.
(b) Where undisturbed earth is not available or not likely to be available to back up pressure-type concrete thrust blocks, the Village Engineer shall specify tie rods with or without anchor-type concrete thrust blocks.
(8) Air release valves. Air release valves shall be placed on the water main at high points as deemed necessary by the Village Engineer to serve as air vents preventing air locking of the water main.
(C) Fire hydrants.
(1) Fire hydrants shall match the hydrants generally installed in the village's water system and shall be furnished by a manufacturer considered standard, and must be approved by the Village Engineer (See Appendix F).
(2) Each hydrant shall be provided with a 6-inch auxiliary gate valve and a 2-foot length of 6-inch pipe between the hydrant and valve.
(a) Two and three-fourths inch threaded steel rods with hex nuts shall be installed to tie the auxiliary gate valve to the water main and connecting tee.
(b) Auxiliary valves shall be provided with valve boxes with covers marked "WATER.
(c) Location.
1. Fire hydrants shall be located at no more than 500-foot intervals.
2. If the location or configuration of a commercial building requires it, then private fire hydrants shall be installed.
3. Hydrants shall be located for easy access by the Fire Department.
(D) Water services. The plans, except for residential developments with individual services for each dwelling unit, shall show the calculated static water pressure at the lowest and highest ground elevations on the site. Calculations shall be presented showing that the proposed water services are of a large enough size to supply an adequate flow of water at the outlet of the meter.
(E) Materials. Water system materials shall be approved by the Village Engineer and shall be as follows: (See Appendix F).
(1) Water main shall be either AWWA or C-900 PVC, having a minimum DR of 18. Both types of pipe shall have mechanical or rubber ring push-on joints.
(2) Water main fitting shall be either cement-lined ductile iron or PVC with joints similar to the pipe joints. Fittings shall be capable of withstanding the same system pressures as the adjacent pipe.
(3) Valves for the mains or for auxiliary fire hydrant valves shall be mechanical joint or push-on joint cast iron bodied, resilient seat gate valves, Mueller, Clow or equal, with bronze-mounted, double disc gate and with non-rising stem and rubber O-ring packing. Each valve shall be furnished with a cast iron road box with a cover marked "WATER."
(4) Fire hydrants shall be Clow Model F2500 or Mueller Centurion hydrants with either mechanical joints or push-on joints. All hydrants shall have a ground-level breakaway flange feature and safety stem coupling. Hydrants shall have 6-inch inlet connections, 5 1/4-inch compression-type main valve openings, two 2 1/2-inch hose connections, and one 4 1/2-inch steamer port with storks fitting, all with National Standard Fire Threads. All hydrants shall include stainless steel bolts on all buried restrained joints, including fire hydrants, megalug fittings and others as determined by the Village Engineer.
(5) Water service pipe shall be Type K Soft Copper Tubing, with a minimum size of 1 inch diameter.
(6) Corporation cocks shall be McDonald or equal, with a minimum size of 1 inch.
(7) Curb stops shall be as noted in Appendix F, or equal, with a minimum size of 1 inch. Each stop shall be furnished with a cast iron Buffalo screw-type box with arch pattern base and cover marked "WATER."
(F) Dry hydrants. The village reserves the right to require one or more dry hydrants for fire district use on any wet bottom detention ponds approved. Location, access easements and materials shall be approved by the Village Engineer and the Fire Protection District with jurisdiction over the subject property.
