OpenFlows Sewer

Sewer system modeling, analysis, and design software

Interoperable sewer modeling and analysis

OpenFlows Sewer is Bentley’s sewer system modeling, analysis, and design software. Engineers use it to plan, analyze, and design sanitary and combined sewer systems with 1D/2D simulation and integrated GIS, CAD, and SCADA data, speeding up their work with AI-assisted workflows. Aufiero Informática distributes Bentley software across Latin America.

It is available in four editions – Essentials, Standard, Advanced, and Ultimate – which include SewerCAD and SewerGEMS, so you can start with a small network and scale up to unlimited-size, complex systems. Contact us to find the right edition for your team.

Improve sewer capacity and reliability

Analyze gravity flow, surcharging, and overflows with advanced 1D hydraulic solvers to identify capacity bottlenecks, reduce flood risk, and optimize system performance.

Accelerate design with integrated workflows

Work seamlessly within CAD and GIS environments to build, synchronize, and update hydraulic sewer models faster using automated design, terrain extraction, and geospatial data integration.

Make smarter operational decisions

Evaluate unlimited what-if scenarios using integrated SCADA data and rainfall-runoff data to assess system behavior, compare overflow mitigation strategies, and support proactive planning and compliance.

Work standalone or in your platform

OpenFlows Sewer can operate as a standalone application or integrated into other platforms, so engineers keep working in familiar environments such as Esri ArcGIS Pro, AutoCAD, and MicroStation. It also runs within Bentley OpenRoads, OpenSite, and OpenRain.

Integrated 1D/2D flood analysis

Connect 1D pipe network elements with 2D surface flow modeling to analyze surface flood depth, velocity, and hazards. Publish and share your hydraulic models in a collaborative digital twin environment for multi-disciplinary reviews.
