上海自来水管线工程公司按传统的给水管道施工工艺、要在通水运营的自来水管道上，为新用户给水，就必须断水开梯分支，这必将造成局部区域内部分停水或降压，给沿线居民、企事业单位带来不便，同时在施工过程中，必须把区域内管网中的自来水排放干净，从而造成大量的清水浪费 Shanghai Water Pipeline Engineering Co., Ltd. According to the traditional construction technology of water supply pipelines and water supply pipelines for water supply to new users, it is necessary to cut off the water to open the ladders, which will inevitably cause partial water cuts or pressure reductions in local areas. Inconvenience caused to residents, enterprises, and institutions along the route, and at the same time during the construction process, the tap water in the pipe network must be discharged, resulting in a lot of water wastage.
