Abstract
DRD technology is a new method to calculate the node water demand based on the monitoring node pressure of the water supply network. This method is able to acquire the water consumption in every node of the monitoring area. Therefore, no flow meter is needed to install on the main pipes. This paper describes the technical details of DRD application and the design of monitoring platform based on wireless sensor network (WSN). A case study is carried out in an actual water supply network and the result shows this method is accurate enough to provide decision support for water supply network management.
