摘要:本设计为无锡高层建筑给水排水工程，内容包括建筑给水系统、热水系统、消防系统、排水系统和雨水排水系统的设计。
室内给水系统采用分区给水方式，地下一层至三层为低区，由市政给水管网直接供水；四到十五层为高区。
消火栓给水系统采用临时高压给水系统。
排水系统采用污水和废水分流制排水系统，生活废污水直接排入市政排水管网，生活污水经化粪池局部处理后再排入市政排水管网。
雨水排水采用外排水的排水方式。
热水系统中热源为建筑物附近的表压为0.20MPa的蒸汽热源。加热器采用半容积式水加热器。给水管材采用三型聚丙烯管（PP-R）管材，排水管道采用硬聚氯乙烯管（UPVC），消防管材选用钢管，热水管材选用交联聚乙烯（PEX）。

Abstract:This project is the water-supply and drainage engineering of wuxi in Jiangsu．It includes the design of Water supply-system、fire water-supply system、sewerage system and rain water system．
The interior water-supply system adopt the way of subregion，the -1~3rd floor is the low district，the source is the municipal water-supply net-work．The4~15rd floor is the high district ．
The fire water-supply system adopt temporary high-pressure system．
The hot water-supply system district is consistent with cold water-supply system，The water heaters are established in underground．
The sewerage system uses the sewage and the waste water separate-sewage system，the waste sewage to disperse into the municipal drainage pipe network directly．The sanitary sewage disperses into the municipal drainage pipe network after disposed in the septic tank．
The rain water system adopt the union drainage system of outdoor system．
Hot water system for the building near a heat source gauge pressure of 0.20MPa steam heat. Semi-displacement type water heater heater. Water pipe using three polypropylene tube (PP-R) pipes, drainage pipes using PVC pipe (UPVC), fire pipe use steel pipe, hot water pipe use cross-linked polyethylene (PEX).
