(A) General.
(1) No residential, commercial or industrial subdivision, or PUD 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 an area 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 one year of the availability of the public water supply system; and
(b) All water supply systems which are installed in the public ways or easements shall be deemed to be dedicated to the village upon acceptance of the subdivision.
(3) Consideration shall be given to water reclamation and reuse in commercial and industrial tracts for the purpose of conservation and relief of demands on existing residential supply.
(4) Evidence shall be presented by the subdivider that the local utilities can satisfactorily serve the area by the utility easements shown.
(5) There shall be no physical connection between a potable and a non-potable water supply.
(B) Design. Water distribution mains shall be of adequate size and shall serve the entire development.
(1) Design. Water mains shall be designed according to the Standard Specifications for Water and Sewer Main Construction in Illinois or according to the Recommended Standard for Water Works, adopted by the Great Lakes Mississippi River Board of State Public Health and Environmental Managers. The more stringent requirements of either shall apply.
(2) Installation.
(a) Said 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 four and one-half 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 six inches, internal diameter, in residential areas and eight inches, internal diameter, in all other areas.
(4) Gridiron or looping of mains.
(a) Each six-inch water main shall be looped (except culs-de-sac or stubbed streets, unless deemed necessary by the Village Engineer) so that runs between connections to six-inch or larger size mains shall not be greater than 1,200 feet.
(b) Each eight-inch water main shall be looped so that runs between connections to mains eight inches or larger shall not be greater than 1,400 feet in a commercial area or 1,800 feet in residential areas.
(c) Each ten-inch water main shall be looped so that runs between connections to mains ten inches or larger shall not be greater than 2,200 feet.
(d) Each 12-inch and larger water main shall be looped so that runs between connections to mains 12 inches or larger shall not be greater than 3,000 feet.
(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 900 feet of main will be shut off at any given time.
(b) If a tee is installed, two 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 30 single-family dwelling units shall be without water with the shutting off of any three 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 and retainer glands are required at all valves, hydrants, tees and bends. Retainer glands must be a type of approved by the Village Water Department.
(a) Engineering drawings shall indicate the location of each thrust block and retainer gland to be installed.
(b) Where undisturbed earth is not available or not likely to be available to back up pressure-type thrust blocks, the Village Engineer shall specify tie rods with or without anchor-type concrete thrust blocks and retainer glands.
(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 by the village.
(2) Each hydrant shall be provided with a six-inch auxiliary gate valve and a two-foot length of six-inch pipe between the hydrant and valve.
(a) Two 3/4-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 having covers marked “WATER.”
(c) Location.
1. Fire hydrants shall be located no more than 400-foot intervals or as approved by the Fire Department and Village Board.
2. If the location or configuration of a commercial building requires it, then private fire hydrants shall be installed.
3. Locate hydrants for each access by the Fire Department.
(D) Water services. The plans, except for residential developments with individual services for each 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 as follows.
(1) Water main shall be either AWWA C-900 PVC, having a minimum DR of 18 or a thickness Class 52, cement-lined ductile iron pipe meeting the requirements of ANSI A21.60 (AWWA C150). 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 approved 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 six-inch inlet connections, five and one-quarter inch compression-type main valve openings, two 2-1/2 inch hose connections, and one 4-1/2 inch pump nozzle, all with National Standard Threads.
(5) Water service pipe shall be Type K Soft Copper Tubing, with a minimum size of one inch diameter, or plastic.
(6) Corporation cocks shall be Mueller Oriseal or equal, with a minimum size of one inch.
(7) Curb stops shall be Mueller Oriseal or equal, with a minimum size of one inch. Each stop shall be furnished with a cast iron Buffalo screw-type box with Minneapolis pattern base and cover marked “WATER.”
(8) All materials must be made in the U.S.A.
