Abstract: 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.

The computer apparatus uses the water demand values to improve the accuracy and resolution of its water flow and pressure estimates.
