OpenFlows

OpenFlows is Bentley Systems’ advanced hydraulic and hydrologic modelling suite used to plan, design, and operate resilient water infrastructure. At Hertford Systems, we utilize OpenFlows to help engineering teams analyze water, wastewater, and stormwater systems with precision and data-driven confidence.

What is OpenFlows?

OpenFlows is Bentley Systems’ comprehensive suite of water infrastructure solutions that enables engineers to model and simulate the complex behavior of water networks. It integrates hydraulic analysis, water quality monitoring, and flood mitigation tools into a unified digital environment. By creating an intelligent digital twin of water assets, OpenFlows allows teams to move from conceptual planning to real-time operational support while maintaining data integrity. The platform supports modern engineering workflows, helping utilities and engineering firms optimize system performance, ensure regulatory compliance, and protect public health through reliable water delivery and management.

OpenFlows provides a complete solution for water, sewer, and stormwater infrastructure, allowing engineers to develop highly detailed models of complex fluid dynamics. Built on Bentley’s industry-leading simulation technology, OpenFlows combines GIS and CAD integration with rigorous hydraulic engines to support every phase of the water lifecycle.

The software enables designers to create accurate distribution models, manage collection system capacity, and simulate various “what-if” scenarios to improve infrastructure resilience. By connecting design data with operational digital twins, OpenFlows improves visibility for all stakeholders and supports better decision-making throughout planning, design, and emergency response. Using OpenFlows, teams can work more efficiently while ensuring the safety and sustainability of vital water resources.

OpenFlows supports a wide range of water infrastructure projects across urban, industrial, and rural environments. Key applications include:

  • Water distribution network modeling and pressure analysis

  • Fire flow testing and emergency response planning

  • Wastewater collection system and manhole capacity modeling

  • Urban stormwater management and flood mitigation planning

  • Water quality simulation and contaminant tracing

  • Energy cost optimization for pumping and operations

  • Integration of hydraulic models with GIS and CAD data

  • Digital twin workflows for real-time water system monitoring

These capabilities allow engineers and planners to design water systems that are more efficient, resilient, and better aligned with long-term environmental goals.
