Bentley water solutions for water loss management and reduction
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:
- Bentley OpenUtilities Designer 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.
- WaterGEMS' Darwin Calibrator* enables modelers to leverage flow and pressure data to find locations for more detailed sonic leak detection.
- With WaterGEMS' Criticality Analysis, engineers can identify areas to be shut down to repair leaks and areas that will be impacted if they don't.
- Sometimes there are leaks that can't be found (unavoidable leakage) or fixed in the near future. In that case, water professionals can use WaterGEMS' Pressure Dependent Demands (PDD) analysis to study the amount that you can expect to reduce leakage by reducing pressure, and look at the impact on customer service.
* Darwin Calibrator module is included with WaterGEMS. WaterCAD users can upgrade to WaterGEMS to utilize Darwin Calibrator.
