区域供水管网DMA规划方案研究

Research on regional water distribution network planning with district meter area method

在区域供水管网规划阶段引入DMA(District Meter Area)理念,根据自然条件并结合管网布局情况,探讨管网分区原则;在给水管网建模基础上对DMA规划方案进行评估。通过模拟计算,本规划方案能满足该区域供水安全要求;通过费用分析,在规划、设计前期实施DMA技术,可有效节省建设成本。避免在现状管网中实施分区造成的不便,为提升供水管网规划及设计水平,提高供水企业管网的管理和运营水平做出有益尝试。

The concept of District Meter Area （DMA） was introduced to the regional water dis tribution network plan stage, and the principles of network sectorization were also studied according to the natural situations and network layout. Based on water supply network model, the DMA plan was evaluated, and the regional water supply safety of this plan was proved by modeling. It was showed that, through cost analysis, the application of DMA before the planning and design could save construction cost effectively. This study found a way to avoid the inconvenience in current network sectorization and offered the positive references for the network planning and designing and the water supply management and operation for the water industry.
