Bentley’s Water Loss Technology
Bentley provides utilities and consulting firms with solutions that let them make the best decisions on controlling water loss, replacing mains, repairing leaks and/or reducing pressure to reduce leakage.
Infrastructure management with Bentley Water
Bentley Water provides engineers with the information they need to identify areas with bad leak history, and perform analysis of whether to replace pipes or continue to repair them.
Water loss control with Darwin Calibrator
The Darwin Calibrator module, which is included in WaterGEMS and available for WaterCAD, lets modelers leverage flow and pressure data to find locations for more detailed sonic leak detection.
Criticality Analysis with WaterGEMS
Criticality Analysis, included in WaterCAD and WaterGEMS, lets engineers identify those areas to be shut down to repair leaks and those areas that will be impacted if they don't.
Pressure Management with WaterGEMS
Sometimes there are leaks that can’t be found (unavoidable leakage) or be fixed in the near future. In those cases, water professionals can use WaterCAD and WaterGEMS’ Pressure Dependent Demands (PDD) analysis to study the amount that they can expect to reduce leakage by reducing pressure, and look at the impact on customer service.
Pipe breakage control with HAMMER
HAMMER can help engineers reduce pipe breakages caused by high pressure transients (or water hammer), identify the areas where breakage is likely to occur, and design surge protection devices.
