水从市政给水管网到用户之间受到污染的情况时有发生,已引起人们的关注。要防止供水过程中的二次污染必须从给水系统的选择、设计,管道和配件的选用、敷设,贮水池、高架水箱的设置,以及管理等方面的细节做起。各卫生监督、市政管理、设计、施工部门及使用者应通力合作,才能避免水的再次污染。 Contamination of water from the municipal water supply network to users has occurred from time to time and has drawn attention. The prevention of secondary pollution in the water supply process must begin with the selection of the water supply system, the design, the selection of pipes and fittings, the laying of the storage tanks, the setup of the elevated water tanks, and the details of management. All health supervision, municipal administration, design, construction departments and users should work together to avoid re-contamination of water.
