Bentley provides utilities and consulting firms with several solutions which can help them make decisions on how best to control leakage: replacing mains, repairing leads and/or reducing pressure to reduce leakage:
* Darwin Calibrator module is included with WaterGEMS. WaterCAD users can upgrade to WaterGEMS to utilize Darwin Calibrator.
As an introduction to water loss management, it is advisable that you read the following article before embarking on a leakage detection study:Tips for Water Loss Management and Leak Detection
Learn more about these solutions by viewing their recorded demonstrations:
1 - Innovative Optimization Model for Water Distribution Leakage Detection, by Dr. Zheng Yi Wu, Bentley:
This paper describes the theory behind the leakage calibration methodology and optimization tool used in WaterCAD and WaterGEMS' Darwin Calibrator.
2 - Using Simulation and Optimization Models for Detecting Water Distribution Leakage, by Paul Sage, United Utilities (U.K.) - BE Conference 2007
Learn how an optimization-based approach can simultaneously quantify and locate water losses using hydraulic model calibration that is formulated as a nonlinear optimization problem which is solved with a genetic algorithm.
