Abstract
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.
