OpenFlows WaterGEMS

Water Distribution Analysis and Design Software

Deliver High-Quality Hydraulic Projects with Minimal Capital Investment

The most flexible and comprehensive solution for water systems engineering, planning, and operations.


OpenFlows WaterGEMS provides you with a comprehensive yet easy-to-use decision-support tool for water distribution networks. The software helps improve your knowledge of how infrastructure behaves as a system, how it reacts to operational strategies, and how it should grow as population and demands increase. From fire flow and water quality simulations, to criticality and energy cost analysis, OpenFlows WaterGEMS has everything you need in a flexible multiplatform environment. OpenFlows WaterGEMS is a superset of OpenFlows WaterCAD.

Intelligent Planning

Efficiently identify potential problems, accommodate service area growth, and plan/prioritize capital improvement projects by using criticality analysis, DMA planning, and pressure management tools to identify potential projects.

Optimized Operations

Use real-time data to analyze energy use and costs, maximize operational efficiencies, minimize disruptions, and intelligently respond to emergencies.

Build and Update Models Faster

Intuitive to use so you can easily jumpstart your modeling process with geospatial data, CAD drawings, databases, and spreadsheets. Apply automated calibration, leak detection, design, rehabilitation, and pump operations.

Identify Water Loss

Use field data to quantify nonrevenue water and help pinpoint loss locations faster.

Assess Fire Flow Capacity

Use automated workflows to access and identify inadequacies in fire protection.
