(A) Fire service water mains.
(1) Fire service water mains shall be installed in accordance with approval plans and the Town Engineering and Public Works Department requirements and specifications for water main construction. Fire service mains shall also be installed in accordance with the National Fire Protection Association standard for the installation of Private Fire Service Mains and Their Appurtenances, NFPA 24, 1992 edition. Conflicting provisions of the Town Engineering and Public Works Department specifications and NFPA 24 requirements should be reported to the Chief of the Fire Department Fire Prevention Bureau.
(2) Fire service water mains, water meters and other appurtenances shall be designed to provide at least 80% of the minimum required fire flow at 20 pounds per square inch residual pressure at the hydraulically most difficult fire hydrant.
(a) It is assumed that other fire hydrants, if provided, will provide a greater quantity of water at the same residual pressure.
(b) When all residential buildings in a multi-family complex are provided with approved residential fire sprinklers, the required fire flow will be reduced 65%.
(3) The required fire flow will be determined utilizing the insurance services office publication, Guide for Determination of Required Fire Flow, 1980 Edition.
(4) Fire Department connections. The Fire Department connections for standpipe or sprinkler systems are important supplements to normal water supplies. Under fire conditions, these devices permit the Fire Department to increase the water supply and pressure to fire protection systems which may be materially reduced by a larger number of sprinklers operating or by the use of hose streams from standpipe risers.
(a) Minimum size pipe shall be four-inch diameter.
(b) All Fire Department inlet pumper connections shall have at least two 2-1/2–inch female swivel connections with National Standard threads and protective caps.
(c) The Fire Department connections at buildings provided with more than two standpipe risers shall have one 2-1/2–inch female swivel connection with National Standard threads, for each additional standpipe riser.
(d) All Fire Department connections shall be located not less than 18 inches, or more than five feet above finished grade.
(e) All Fire Department connections shall be provided a clear space of ten feet horizontally and vertically in all directions.
(f) All Fire Department connections shall be readily visible and not more than 50 feet
from a street, fire lane or similar area providing access to Fire Department apparatus. The area between the connection and vehicular access shall be free of obstructions.
(g) There shall be an approved pumper fire hydrant within 200 feet of the Fire Department connection measured along an approved path of travel for the fire apparatus.
