Trying to describe how Bentley鈥檚 OpenFlows WaterGEMS (and OpenFlows WaterCAD庐) can help a water system engineer or operator can be difficult. Users need to think of the software not as a tool, but rather a toolbox comprised of advanced hydraulic analysis capabilities. Depending on the problem you need to solve, it could be deployed as a means to size pipes, select pumps, identify pressure zone or district meter area (DMA) boundaries, predict chlorine residuals, or plan flushing operations.
