High-Pressure System in Brooklyn.
The high-pressure system for fire protection has just been successfully tested in Brooklyn, New York. The spot selected was India wharf, Atlantic basin, the pressure being furnished from the St. Edward’s street station. Till the signal was sent by telegraph to that station six 2 1/2in. hose streams were thrown under hydrant pressure. As soon as the pumping station was telegraphed to, the pressure ran up at once to 100 lb., and the discharge of 2,300 gal. per minute was increased by 200. Six 3-in. lines were then connected with a water tower, on which the pressure was increased to 200 lh. ‘ The total capacity of the twelve streams was 6,500 gal., which was increased hv 1,500 gal. under an additional pressure of 50 lh. To enable the firemen to handle the line of hose, nozzle-tripods were employed. In those the hose was so securely locked that only four or five men were needed to handle it—two at a pinch, except when the hose had to he moved forward. The pressure was easily controled by an additional telephone system installed in the high-pressure area and operated at any point in that area. Hydrants are set on every 200 ft. in the high-pressure area. At present only the St. Edward’s street pump, in the Fort Greene district, is ready for use. Its capacity is 9,500 gal. per minute. That of the Joralemon street station, which can also draw on the salt water, but only in case of great emergency, is 16,500 gal.
