摘要:本建筑为十四层综合楼。1-2层为营业大厅和会议室等，其余各层为各种功能公用房间。主要包括给水系统、排水系统、消防系统、和热水系统四个部分。

　　　给水系统采用分区供水，一到三层为低区，由市政管网直接供水。三层到十四层为高区，采用上行下给的供水方式，由供水泵供水到屋顶的高位水箱，再由高位水箱向高区管网供水；排水系统采用的是污、废分流制，排水立管仅设伸顶通气管，污水再经化粪池处理后排向市政污水管网；消防系统设计成消火栓灭火系统，火灾初期10min的水由消防水箱供给，正常供水由消防水泵从贮水池内抽取。热水采用的是封闭式机械半循环系统，分区情况和冷水系统一致，冷水通过电加热器集中加热后，再由提升泵供向配水管网。
