A system that provides 1½ inch (40 mm) hose stations (closets and cabinets used to contain fire hose, nozzle and other accessories connected with standpipe system and they do not interfere with the prompt use of the hose connection and other equipment at the time of fire) to supply water for use primarily by trained personnel or by the fire. Most standpipes have a system demand of 750, 1,000, or 1,250 gallons per minute (gpm), and a pump can be used to supply a system that has a demand of 100% to 150% of the pump’s flow capacity. This standard dates back to 1912 and has been revised many times since.
