饮用水安全是人类生活的基本保障，因此饮用水监测是一个重要的公共卫生问题。多年来，已经开发了许多程序来监测水处理厂的水质。供水系统的监测受到的关注较少。本次交流的目的是通过确保对从水厂到客户的分配网络的监控来研究饮用水安全问题。该系统是基于由传感器网络提供的余氯浓度的观察。检测问题的复杂性是由于配水管网的复杂性和水消耗的动态配置文件。水污染的开始时间和地理位置尚不清楚。它的持续时间也是未知的，但有限。此外，余氯浓度，这是修改的污染，也是时间依赖性的，因为它们是耗水量的函数。第一个，即参数的方法，利用水力模型来计算标称余氯浓度。第二种方法，即非参数方法，是一种利用历史数据的统计方法。最后，计算出污染物可能进入的区域和污染的传播，并显示给操作用户。
Monitoring drinking water is an important public health problem because the safe drinking water is essential for human life. Many procedures have been developed for monitoring water quality in water treatment plants for years. Monitoring of water distribution systems has received less attention. The goal of this communication is to study the problem of drinking water safety by ensuring the monitoring of the distribution network from water plant to customers. The system is based on the observation of residual chlorine concentrations which are provided by the sensor network. The complexity of the detection problem is due to the water distribution network complexity and dynamic profiles of water consumptions. The onset time and geographic location of water contamination are unknown. Its duration is also unknown but finite. Moreover, the residual chlorine concentrations, which are modified by the contamination, are also time dependent since they are functions of water consumptions Two approaches for detection are presented. The first one, namely the parametric approach, exploits the hydraulic model to compute the nominal residual chlorine concentrations. The second one, namely the nonparametric approach, is a statistical methodology exploiting historical data. Finally, the probable area of introduction of the pollutant and the propagation of the pollution are computed and displayed to operational users.
