Where an existing public or private central water supply is available and has been approved by the Chester Volunteer Fire Department for minimum fire fighting purposes, fire hydrants shall be installed at appropriate locations as recommended by the Fire Official and at distances between hydrants not exceeding 1,000 feet. The entire existing central water supply system and each new hydrant shall have a capacity to provide a minimum flow rate of 1,500 gpm at 20 psi residual pressure for a minimum duration of two hours. Hydrants shall be installed in accordance with ANSI/AWWA C 502, Dry Barrel Fire Hydrants, latest edition; painted as directed by the Fire Official; and tested in accordance with NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants, latest edition, to ensure compliance with fire flow requirements. Acceptance test data shall be provided to the Fire Official for review and approval. In areas where public or private central water supply is available, but such water supply does not have the capacity to satisfy the foregoing minimum standards, such central water supply system shall be supplemented with additional measures to satisfy the minimum fire protection requirements of the Borough. Such additional measures may involve any one or a combination of the following: installation of booster pumps with appurtenances, installation of underground water storage tanks with appurtenances, creation of drafting points with appurtenances, or such other means of increasing fire fighting capability as may be recommended and approved by the Fire Official.
