A computer apparatus runs a hydraulic model using real-time or near-real-time data from an Automated or Advanced Metering Infrastructure (AMI), to improve model accuracy, particularly by obtaining more accurate, higher-resolution water demand values for service nodes in the model. Improving the accuracy of water demand calculation for the service nodes in the model stems from an improved technique that more accurately determines which consumption points in the water distribution system should be associated with each service node and from the use of real-time or near-real-time consumption data. The computer apparatus uses the water demand values to improve the accuracy and resolution of its water flow and pressure estimates. In turn, the improved flow and pressure estimation provides for more accurate control, e.g., pumping or valve control, flushing control or scheduling, leak detection, step testing, etc.

Method and apparatus for model-based control of a water distribution system

A system for managing a distribution network, the system including a network hydraulic model and an automated meter infrastructure (AMI) providing AMI data from consumption meters. The system includes subnetworks within the distribution network, nodes interconnecting the subnetworks, and boundary devices connected to the nodes. Each boundary device includes a flow meter and a pressure sensor that sense a flow and a pressure of the distribution network at the nodes at a given time step. A subnetwork hydraulic model is generated for each subnetwork from the network hydraulic model. A processing module determines a first comparison for the given time interval between the AMI data from the consumption meters within a given subnetwork, the flow and the pressure at the nodes bordering the given subnetwork, and the subnetwork hydraulic model for the given subnetwork. The distribution network is managed based at least in part on the first comparison.
