【正文】 ire hydrant system and automatic sprinkler system) and roof drainage system for the level 17th high plex building are designed. The water supply system is applied by vertical division block. The floors from the negative to the third are the low areas, water of which is supplied directly by the municipal pipe work. The floors from the 4th to the 11th are the middle areas and the floors from the 12th to the 17th are the high areas,water of which are all supplied with the frequency conversion pump group. The drainage system is an interflow system of sewerage and waste water. Water of the first floor drains separately, the upright draining pipes are equipped with the ventilating pipes, and then the sewerage is disposed by the septic tanks and drains to the municipal waste pipe work. The fire system includes the fire hydrant system and automatic sprinkler system. The roof drainage system is an outside drainage system.
