Senior-engineer perspective
Use the network model to test hydraulic decisions before they reach the field.
OpenFlows Sewer is the current Bentley family for sanitary, combined and sewer collection-system modeling, consolidating the capabilities historically marketed as SewerCAD and SewerGEMS.
Compare hydraulic scenarios before committing capital or operational changes.
Connect network data, engineering models and design decisions with fewer manual handoffs.
Apply gravity and pressure sewer hydraulic modeling where that capability directly supports the project decision.
Technical scope
Hydraulic and operational functions for system-level decisions.
Only capabilities supported by the reviewed source-controlled product record are shown here. CTtec adds engineering context without reproducing Bentley marketing copy.
Gravity and pressure sewer hydraulic modeling
Wet-weather runoff, surcharge, overflow and pump-station analysis
Scenario management, automated sewer design and 1D/2D capabilities by tier
Engineering workflow
System data in. Calibrated scenarios and design decisions out.
The sequence is assembled from the product's reviewed capability/application data and CTtec discipline vocabulary. It is a project-use model, not a claim that every project follows an identical process.
Engineering inputs
Network topology, assets, demand/loading data, operating rules and field/GIS information
Core engineering work
Gravity and pressure sewer hydraulic modeling
Validation & review
Wet-weather runoff, surcharge, overflow and pump-station analysis
Project outcome
Sanitary sewer master planning. Hydraulic decisions, design scenarios and operational planning outputs
Connected handoff
GIS/CAD/terrain imports
Engineering applications
Network decisions where scenario comparison matters.
These application areas come directly from the reviewed product record. They are presented as decision contexts rather than padded with repeated generic prose.

Product selection guidance
Choose the OpenFlows workflow that matches the hydraulic question and network scale.
Selection guidance is CTtec engineering editorial based on the reviewed product scope. It is intended to support tool choice, not replace project-specific engineering judgement.
Use OpenFlows Sewer for wastewater/collection-system hydraulics, wet-weather capacity, overflow and pump-station studies.
Use OpenFlows Storm when the design scope is site/municipal storm drainage and detention; use FLOOD for broad 2D surface flood behavior.
- Confirm the current Bentley system requirements and licensing terms before deployment.
- Validate project data standards, coordinate systems, units, and exchange formats during implementation planning.
Connected engineering workflow
Interfaces, handoffs and adjacent Bentley applications.
Connections are shown only where they are present in the reviewed product record.
Engineering & commercial FAQ
Questions to resolve before the tool becomes part of the project workflow.
Answers use the reviewed product data, CTtec engineering editorial, Bentley public pricing and clearly separated CTtec sales-support context.
When should an engineering team choose OpenFlows Sewer?
Use OpenFlows Sewer for wastewater/collection-system hydraulics, wet-weather capacity, overflow and pump-station studies. Use OpenFlows Storm when the design scope is site/municipal storm drainage and detention; use FLOOD for broad 2D surface flood behavior.
What engineering work does OpenFlows Sewer support?
Gravity and pressure sewer hydraulic modeling; Wet-weather runoff, surcharge, overflow and pump-station analysis; Scenario management, automated sewer design and 1D/2D capabilities by tier.
What project applications are a good fit?
Sanitary sewer master planning; Capacity/overflow studies; Collection-system design and rehabilitation.
Which Bentley editions or tiers are represented here?
The reviewed Bentley source lists Essentials, Standard, Advanced, Ultimate. Reference values on this page are a dated public-source snapshot checked 2026-09-18, not a CTtec quotation.
How does OpenFlows Sewer connect to the wider engineering workflow?
The reviewed workflow references GIS/CAD/terrain imports; OpenRoads, OpenSite and MicroStation; SCADA and digital-twin review. Confirm project-specific exchange requirements during implementation planning.
What legacy or alternate names may engineers search for?
OpenFlows Sewer is also relevant to searches for SewerCAD, SewerGEMS. CTtec keeps those terms for continuity without presenting obsolete names as separate current products.
What is the public price authority on this page?
Bentley public pricing is the sole public product-price authority shown on CTtec.ae. CTtec can assist with quotations, licensing and procurement support, but the website does not publish a separate regional product price.
What should the team check before deployment?
Confirm the current Bentley system requirements and licensing terms before deployment. Validate project data standards, coordinate systems, units, and exchange formats during implementation planning.
