OpenFlows Water
OpenFlows Water can help engineers plan, design and analyze water systems.
Key Features
Scenario management
Perform several hydraulic modelling scenarios using different data sets to simulate the system under various hypothetical conditions. Analyze the criticality of pipes and valves to identify the weak links in your water distribution system.

Transitional simulation
Use hydraulic analysis software and ram strokes to effectively identify, manage and reduce risks associated with transient events.

Hydraulic modelling
Quickly create your hydraulic model by synchronizing network data from standard formats, including GIS and CAD files, databases and spreadsheets. Be compatible with different formats and data sources.

Calibration of model
Apply an AI-driven automated calibration with Darwin® Calibrator and make sure your model is accurate in all circumstances — peak days, component failures, fire flows or future needs — eliminating differences between the model and field data.

Design optimization
Use Darwin Designer to automatically determine maximum pressures, most economical designs and rehabilitation strategies based on available budget, construction cost, pressure and speed constraints.

User Word
OpenFlows Water helped us evaluate proposals to improve Olinda's supply network, which will benefit more than 250,000 local residents, workers and visitors. This is just one example of the importance of this solution for sanitation enterprises, as it helps to improve living conditions. Bentley plays a key role in this process.

Licensing Options
Annual rental
The simple and efficient way to use software over a fixed period of 12 months. The license is associated with the user and can be used on several posts (but not simultaneously).
The annual subscription includes a number of "keys" that can be exchanged for training or accompaniment (mentoring).
Perpetual licence
A perpetual license is a unique purchase, it can be accompanied by an annual maintenance contract called SELECT. The latter assures you that your software is always up to date, 7 days a week and 24 hours a day support and allows for the buoyancy of licenses among other services.
The SELECT contract offers maintenance for your perpetual licenses including various benefits:
- Floating licences
- Software updates
- Balancing the licensing portfolio
- Technical assistance 24/7, 365j/365
- CONNECT services
