Spring Valley Fire Dept. is composed of three companies. Columbian Engine Co. who responds with two pumpers. Rockland Hook and Ladder Co. who responds with a Tower ladder, Rescue and ambulance and Spring Valley Hook and Ladder who responds with the tower ladder and a pumper. First in engine is the initial attack and drops a five inch supply line from closest hydrant to the scene and if needed the second in engine supplies the first. The tower ladders, in accordance with SOP take front and rear of building. If we need the stick to the roof the driver runs the ladder. In most cases the pump is used to supply the pressure to the stang mounted on the bucket. Our sop calls for five inch supply lines, three and half inch lines on fire ground to supply engine to ladder, and the Columbians use inch and three quarter attack lines and the Hill hooks (SVHL) use two inch. In almost all cases the ladders do ladder work and the engines engine work. They have enough manpower for this to work out well for them. Spring Valley also has an excellent large mains hydrant system. The ladder trucks carry five inch hose and if the situation calls for it can lay a line on the way in and be self sufficient. Long winded but hope this makes some sense of how they do it.
