摘　　要：随着海水淡化技术日益成熟,工程规模也越来越大,淡化水在解决淡水资源短缺的今天发挥着巨大作用,淡化水将大规模地应用到市政给水。从淡化水的安全性和对管网的影响,阐述了淡化水的特殊性,并根据其特点提出了达到常饮水标准,提高水质化学稳定性,减轻对管道的腐蚀,稳定水力条件,减轻"黄水"现象出现的工程措施。The desalinated water is playing much more important role in solving the shortage of freshwater resources all around the world, especially with the seawater desalination technology becoming more and more mature and the project scales increasing much larger, the desalinated water will be extensively applied to municipal water supply system. In this article ,the characteristics of the desalinated water will be illustrated from two aspects： the health and safety as one kind of drinking water as well as the effects on the distribution system. According to such water＇s characteristics, some countermeasures were proposed to improve water chemical stability, to mitigate corrosion of pipelines, to keep stable hydraulic conditions of distribution system, and to avoid the pHenomena of ＂yellow＂water.
