(A) Public water supply.
(1) Water mains not less than six inches in diameter shall be constructed throughout the entire subdivision. Larger diameter pipes may be required by the village to provide for future transmission needs, in which case, the village shall pay any incremental costs, over and above the costs to install a six-inch main. All mains shall conform to SDR 21 requirements and shall be installed with No. 12 insulated tracing wire, secured at every joint with duct tape and exposed in every valve box.
(2) Every water supply system shall be designed in such a manner as to provide an area fire flow meeting the requirements established by the Fire Safety Division of the Fire Department. Water mains larger than six inches in diameter shall be installed at the subdivider's expense if needed to provide the area fire flow required by the Insurance Services office guild for determination of required fire flow. A minimum of 1,000 gallons per minute with a residual pressure of 20 pounds per square inch shall be required. Fire hydrants with shut-off valves at each hydrant shall be installed throughout the entire system at maximum intervals of 600 feet or less if required by the Fire Protection District. All fire hydrants shall be three nozzle hydrants with threads as specified by the Chatham Fire Department and shall have flow characteristics similar to those of a five and a quarter inch hydrant valve.
(3) All fire hydrants installed on roads with 50-foot rights-of-way shall be located as shown in Appendix A-7. All fire hydrants installed on roads with 60-foot rights-of-way shall be standard "tees".
(B) Private water supply. When a public water supply is not feasible and the subdivision is outside the corporate limits of Chatham, a private well may be used. Wells shall be constructed according to the Illinois Water Well Pump Installation Code. The lot owners will be required to connect to the Village of Chatham water system at such time as a public water main has been extended to within 200' of any portion of the owner's property.
