重庆DMA构建模式探索与实践

Exploration and practice of DMA construction mode of water supply network in mountainous cities

为构建供水管网漏损管控体系,降低管网漏损率,重庆结合山地城市地形高差大、供水范围广、供水管网复杂、外部条件恶劣的区域特点,使用干管+独立子网的方式,构建了山地城市组团供水管网DMA。在北碚DMA示范区的实际运用中,通过专项研究体系以及科技部国家重点研发计划课题成果的指导,摸索出一整套数据分析方法,从而实现了对该区域管网的精准监控,区域漏损率降低到7.22%。

In order to construct the leakage control system of water supply network and reduce the leakage rate of pipe network,combining the regional characteristics of mountainous cities,such as large topographic difference,wide water supply range,complex water supply network and harsh external conditions,and using the method of separating mainpipe from branch pipe,Chongqing constructs the mountain city cluster water supply network DMA.In the practical application of Beibei DMA demonstration area,under the guidance of the National Key R&D Program of China,a complete set of data analysis methods have been explored to realize accurate monitoring of the regional pipe network.The leakage rate of Beibei’s pipe network has decreased 7.22%.
