Bentley OpenFlows Water Ultimate 2026 v26.00: Complete Water Distribution Modeling & Management

Bentley OpenFlows Water Ultimate 2026 v26.00 is a comprehensive hydraulic modeling solution for the analysis, design, and operation of water distribution systems. Trusted by thousands of engineers daily, it combines the most advanced capabilities from WaterCAD (intuitive modeling), WaterGEMS (advanced engineering tools), and HAMMER (hydraulic transient analysis) into a single, powerful environment .

The Ultimate edition is distinguished by additional AI capabilities and full transient analysis, providing an unparalleled toolkit for tackling complex system challenges—from fire flow analysis and pump energy optimization to water quality modeling and infrastructure renewal planning . Its hallmark features include advanced interoperability (GIS, CAD, SCADA), a genetic algorithm solver for calibration and design optimization, and robust support for sustainable, resilient system management.

OpenFlows Water provides the superior interoperability and flexibility required for planning, designing, building, and operating sustainable water systems.

⚡ Key Features & Capabilities

???? Hydraulic & Water Quality Modeling (WaterGEMS)

  • Extended Period Simulation (EPS): Model system behavior over time (tank levels, pump status, pressure changes).

  • Water Quality Analysis: Simulate chlorine decay, water age, source tracing, and contaminant transport.

  • Fire Flow Analysis: Calculate available flow at hydrants under specified residual pressure.

  • Pump & Valve Modeling: Headloss analysis, variable speed pumps, and control valve (PRV, PSV) simulation.

⚡ Transient Analysis (HAMMER)

  • Surge & Waterhammer Simulation: Unsteady flow analysis due to pump trips, valve closure, or column separation.

  • Air Vessel & Surge Tank Modeling: Design protection devices to mitigate damaging pressure surges.

????️ Design & Optimization (WaterGEMS)

  • Genetic Algorithm (GA) Optimization: Automatically sizes pipes, schedules pumps, and calibrates models to field data.

  • Criticality & Segmentation Analysis: Identify isolation valve criticality and system resilience.

???? AI Capabilities (Ultimate Edition)

  • AI-Assisted Calibration: Automated model adjustment to match field measurements (pressure, flow).

  • Predictive Analytics: Forecast system behavior under varying demand scenarios (machine learning integration).

???? Scenario Management & Decision Support

  • Scenario Management Center: Compare alternatives (what-if analyses, capital improvements) side-by-side.

  • Darwin Designer: Automated pipe sizing and rehabilitation optimization based on cost vs. performance.

???? Interoperability & Data Integration

  • GIS Integration: Directly read/write Shapefiles, Geodatabases (ESRI), and use ModelBuilder for automated network creation.

  • CAD & BIM: Import/export DXF/DWG, leverage drawings as backgrounds, and export to iModel.

  • SCADA Connect: Real-time data integration for operational models (pressure, flow, tank levels).

???? System Design & Master Planning

  • Water Distribution Design: Pipe sizing, pump selection, tank sizing, and fire flow compliance.

  • Asset Management: Prioritize pipe replacement based on hydraulics, age, and criticality.

  • Energy Analysis: Calculate pump energy consumption (kWh) and cost; optimize pump schedules.
