Before the installation or alteration of an inside standpipe system required by the provisions of this Code, a plan, setting forth all essential details of the inside standpipe system, shall be submitted to the Fire Commissioner. Such plan shall include hydraulic calculations. Upon finding that the plan conforms to the requirements of the Code and after payment of standpipe permit fees hereinafter specified, said plan shall be approved by the Fire Commissioner.
The fees charged in connection with an inside standpipe system shall be as follows:
If the plan does not conform to the requirements of the Code and a revised plan is submitted, the fee for each revised plan submission shall be $200.00. For the approval of the standpipe plan and the initial inspection of the inside standpipe system required by the provisions of this code, a fee of $300.00 shall be charged for the first standpipe riser and $100.00 for each additional standpipe riser. For the test of a fire pump used in connection with an inside standpipe system, a fee of $31.50 for each unit of pumping capacity of 50 gallons per minute or fraction thereof shall be charged with a minimum permit fee of $315.00.
(Prior code § 91-55; Amend Coun. J. 12-15-92, p. 27387; Amend Coun. J. 10-30-96, p. 31261, § 1; Amend Coun. J. 5-18-16, p. 24131, § 126; Amend Coun. J. 11-14-18, p. 90376, Art. V, § 5)
After completing a standpipe system installation, the contractor shall submit to the fire commissioner a written certification that the system has been installed in accordance with the plans approved by the fire commissioner.
(Prior code § 91-56; Amend Coun. J. 10-30-96, p. 31261, § 1; Amend Coun. J. 5-18-16, p. 24131, § 127)
Inside standpipe systems may be:
(a) Wet, in which the pipes are kept filled with water.
(b) Dry, in which a portion of the piping nearest the hose outlets normally is kept filled with air under pressure and so arranged that the operation of an outlet will automatically admit water to the system. Dry systems shall be used only when a wet system is impractical on account of a deficiency of heat in the area in which piping is located.
(c) Manual dry, in which a permanent water supply is not attached to the system, and which requires water from a Fire Department pumper to be pumped into the system through the Fire Department connection in order to meet the system demand. Manual dry systems shall be used only as provided in Section 15-16-090(a)(5).
(Prior code § 91-57; Amend Coun. J. 10-30-96, p. 31261, § 1; Amend Coun. J. 1-23-19, p. 94952, Art. II, § 2)
The water supply for inside standpipe systems shall be taken from a source sufficient to provide a minimum pressure of 65 pounds per square inch with 500 gallons per minute flowing at the highest hose outlet. The total water supply capacity shall be not less than 500 gallons per minute for the first standpipe and 250 gallons per minute for each additional standpipe riser, but no standpipe system need have a capacity greater than 1,500 gallons per minute. The water supply shall be capable of providing the required flow for not less than one-half hour.
(Prior code § 91-58; Amend Coun. J. 10-30-96, p. 31261, § 1)
Where fire pumps are used to meet the water supply requirements, the minimum capacity of such pumps shall be 500 gallons per minute at a pressure of not less than 100 pounds per square inch. However, no one pump need have a capacity of more than 1,500 gallons per minute.
(Prior code § 91-59; Amend Coun. J. 10-30-96, p. 31261, § 1)
