Water distribution systems present a significant challenge for structural monitoring. They comprise a complex network of pipelines buried underground that are relatively inaccessible. Maintaining the integrity of these networks is vital for providing clean drinking water to the general public. There is a need for in-situ, on-line monitoring of water distribution systems in order to facilitate e...

Efficient management of water distribution networks (WDNs) is currently a focal point, especially in countries where scarcity conditions are more and amplified by frequent drought periods. In these cases, fact, pressure becomes the fundamental variable managing WDNs. Similarly, WDNs often obsolete affected several points losses. Leakages mainly pressure; utilities usually apply technique to red...

Background and objectives: The scattered state of villages both from their geographic aspect and the distance between residential units within a single village has made the task of supply, distribution and monitoring the quality of water a difficult one. Ideas of experienced people in the field of rural water quality control, has been obtained to reach gain a view on existing difficulties in su...

1. Abstract Near real-time continuous monitoring systems have been proposed as a promising approach for helping drinking water utilities detect and respond quickly to threats related to the normal operation of the water network. Water quality sensors may detect contamination events that pose a growing threat to public health, while pressure and flow sensors are used for estimating the hydraulic...

Recent advances in real-time water sensing technology have enabled new opportunities for improved assessment and management of water distribution systems. The implementation of WaterWiSe, a real-time, on-line hydraulic and water-quality monitoring system in Singapore is helping improve efficiency and maintaining supply standards across the water distribution network. As its primary data source,...
