摘　　要：武汉市汉阳区部分供水区域,由于各种具体原因,长期存在供水管网水压过低现象,属汉阳供水管网供水不利区域。为此多次采取局部管网改造、安装二次供水设施等解决措施,均未获得长期良好效果。为改善该类区域供用水不足的状况,武汉市水务集团运用分区计量技术(DMA),采取供水管网区块化、封闭叠压供水相结合的模式,对局部供水管网进行了改造,取得了良好的效果。Due to various specific reasons, part of the water supply area of Hanyang district wherethe long-term phenomenon of low pressure water supply exists, is water supply unfavorable area of Han-yang water supply pipe network. For this, the solutions of local pipe network transformation and installingsecondary water supply facilities were taken, but no long-term good results were achieved. To improve thesituation of lack of water in such areas, Wuhan Water Group adopted DMA technology and the mode com-bining the water supply pipe network block with closed additive pressure water supply to transform the lo-cal water supply pipe network, and good results were achieved.
