OpenFlows WaterGEMS is a hydraulic modeling application for water distribution systems with advanced interoperability, geospatial model building, optimization, and asset management capabilities. From fire flow and water quality analyses to energy consumption and capital cost management, OpenFlows WaterGEMS provides an easy-to-use environment for engineers to analyze, design, and optimize water distribution systems. WaterGEMS takes advantage of Bentley CONNECTservices by associating a hydraulic model with a CONNECT project.
