必须在各级采取行动，以确保对所有配水网络中的饮用水质量进行优化管理:控制饮用水处理厂出口的一些特定参数，如溶解有机物含量、腐蚀性、颗粒物含量，并保证完美消毒；通过应用水力模型和使用质量模块来预测氯减少、细菌增殖和颗粒沉积区，对网络有很好的了解。由于我们开发的Piccolo软件的新质量模块，这些建模现在成为可能；基于使用模型选择采样点和使用在线传感器的网络监控策略。 为此，作者讨论了基于微电子技术的余氯微传感器和自动检测大肠菌群的分析仪的发展；质量管理需要一种智能氯化策略，在正确的地方使用正确的剂量，还需要使用更具创新性的解决方案，就像卫星膜处理示范工厂所使用的那样，该工厂将超滤与纳滤相结合。配水网络是大型反应堆，是饮用水生产厂的延续，为这些网络开发适当的现代监测、预防和处理解决方案非常重要，以确保供水的可靠性、质量和安全。

Action, at various levels, is necessary to ensure optimum management of drinking water quality in all distribution networks: Controls of some specific parameters at outlet from drinking water treatment plants, such as dissolved organic content, corrosivity, particle content, and a guarantee of perfect disinfection; A good knowledge of the network through the application of hydraulic models and the use of quality modules to predict chlorine decrease, bacteria proliferations and particle deposit zones. These modelings are now possible thanks to the new quality modules of the Piccolo software we have developed; A network monitoring strategy based on the choice of sampling sites using models, and the use of online sensors. For this purpose the authors discuss the development of residual chlorine microsensors based on microelectronic techniques, and analyzers which automatically detect coliforms; Quality management requires an intelligent chlorination strategy, with the right dose being applied in the right place, and also the use of more innovative solutions, as used in the satellite membrane treatment demonstration plant, which combines ultrafiltration with nanofiltration. Distribution networks are vast reactors which are a continuation of the drinking water production plant, and it is important to develop appropriate modern monitoring, prevention and treatment solutions for these networks, in order to guarantee water supply reliability, quality and security.
