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 and is available for WaterCAD (for an additional fee).
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.
3 - Use of Hydraulic Model for the Optimization and Losses Reduction Planning -The Passagem Funda Distribution System, by Nivaldo Rodrigues da Costa Jr, SABESP (Brazil):
This work presents the planning for optimization and reduction of water losses in Passagem Funda system, an area with 274 km of pipes and high pressures.
