摘　　要：闻喜县南垣集中供水工程设计解决裴社乡等5个乡镇78个自然村的饮水安全问题。根据项目区各个用水村的分布和供水压力需求情况,规划采用南北分片供水的总体方案。北干线首部加压和中部减压相结合,南一干重力配水,南二干分两级减压供水。这样做不但提高了系统运行的可靠性,而且较大程度地降低工程的总体造价和工程投资。The central water-supply project in Nanyuan of Wenxi County solves drinking water safety problems of 78 villages in five towns including Peishe village etc.. According to distribution and discharge head requirements of users, the design adopts overall plan of dividing south networks and north ones. The north main pipe combines header pressurization with middle decompression, the first south one uses gravity distributing water, and the second south one reduces water pressure twice. Not only the scheme enhances system operation reliability, but also it cuts down project costs and investments to more extent.
