For organizations that need accurate water distribution system modeling software, Bentley OpenFlows Water remains a serious solution for improving system reliability, planning network upgrades, and supporting data-driven infrastructure decisions.

Introduction

Water distribution systems are often more complicated than they appear. A network may contain hundreds or thousands of pipes, multiple pumps, storage tanks, pressure zones, control valves, and changing customer demands. A small change in one part of the system can affect pressure and flow across the entire network.

This is where hydraulic modeling software becomes essential.

Bentley OpenFlows Water is built to help engineers analyze water distribution networks in a digital environment. Rather than testing every possible scenario in the field, professionals can create a hydraulic model and evaluate how the network is expected to perform under different conditions.

For example, an engineer may need to answer questions such as:

• Will a new residential development receive sufficient water pressure?
• What happens if a major pipe fails?
• Can an existing pump station support future demand?
• Where are pressure losses occurring?
• Can a new storage tank improve system performance?
• Will the network provide adequate fire flow?
• Which pipes should be upgraded first?

Bentley OpenFlows Water helps answer these questions through structured hydraulic analysis, scenario testing, and engineering workflows.

What Is Bentley OpenFlows Water?

Bentley OpenFlows Water is a professional water distribution modeling solution used for planning, designing, analyzing, and managing pressurized water networks.

It is aimed primarily at:

• Water utility engineers
• Civil and hydraulic engineers
• Municipal infrastructure departments
• Engineering consultants
• Industrial facility designers
• Water network planners
• Infrastructure asset management teams

The software can be used to model components such as pipes, junctions, pumps, tanks, reservoirs, valves, and other network elements. Engineers can then analyze hydraulic behavior based on demand, elevation, pipe characteristics, operating conditions, and other design parameters.

One of the key strengths of the Bentley OpenFlows Water workflow is its ability to support both existing network analysis and future infrastructure planning. Users can evaluate current system performance while also creating proposed design alternatives.

Key Features of Bentley OpenFlows Water

1. Advanced Hydraulic Modeling

At the core of Bentley OpenFlows Water is hydraulic analysis. Engineers can model how water flows through a pressurized network and evaluate important parameters such as:

• Flow rates
• Pressure
• Head loss
• Hydraulic grade
• Pipe velocity
• Pump performance
• Tank levels
• System demand

This allows professionals to identify weak points in a water distribution system before they become expensive operational problems.

2. Water Distribution Network Design

Designing a new network requires careful consideration of pipe sizes, pressure requirements, elevation changes, demand projections, and future growth.

Bentley OpenFlows Water can help engineers compare design alternatives and determine whether proposed infrastructure is capable of meeting expected requirements.

For example, an engineering team designing a new development can test several pipe configurations and evaluate the expected pressure at different locations. This provides a more reliable basis for selecting pipe diameters and network layouts.

3. Pump and Pump Station Analysis

Pump stations are critical components of many water systems. Poorly selected pumps can lead to excessive energy consumption, inadequate pressure, or unstable system operation.

Bentley OpenFlows Water supports pump-related analysis, helping users evaluate how pump operation interacts with the rest of the network.

Engineers can investigate:

• Pump operating conditions
• System head requirements
• Flow behavior
• Pump efficiency considerations
• Multiple pump configurations
• Operational scenarios

This is particularly useful when planning upgrades to existing pump stations or evaluating future demand.

4. Pressure and Flow Analysis

Maintaining appropriate pressure is one of the most important responsibilities in water network design.

Too little pressure can result in poor service, while excessive pressure can increase leakage and place unnecessary stress on infrastructure.

Bentley OpenFlows Water enables users to analyze pressure throughout the network and identify areas that may require:

• Larger pipes
• Pressure-reducing valves
• Booster pumps
• Additional storage
• Network reconfiguration

This makes the software valuable for both new construction and rehabilitation projects.

5. Scenario and Alternative Analysis

Real-world water networks rarely operate under one fixed condition. Demand changes throughout the day, seasons change, equipment may be unavailable, and future developments can alter system requirements.

Scenario modeling allows engineers to test different conditions without rebuilding the entire model.

Common scenarios may include:

• Average day demand
• Maximum day demand
• Peak hour demand
• Fire flow conditions
• Pump failure
• Pipe shutdown
• Future population growth
• Emergency operating conditions

This type of analysis helps infrastructure teams prepare for both expected and unexpected situations.

6. Fire Flow Analysis

Fire protection requirements are an important part of water distribution planning.

A network may appear to perform well during normal demand but experience significant pressure drops during fire flow conditions. Bentley OpenFlows Water can help engineers assess whether critical locations have sufficient available flow and pressure.

This provides valuable information for municipalities, developers, and consultants working on commercial, residential, and industrial projects.

7. Integration with Engineering Workflows

Bentley OpenFlows Water is designed for professional infrastructure workflows. Depending on the project environment and connected Bentley technologies, engineers can work with engineering data and network information more efficiently.

This is particularly useful for organizations managing large infrastructure projects where design, analysis, mapping, and asset information need to work together.

Practical Use Cases

Municipal Water Distribution Planning

Municipalities often need to understand whether existing water networks can support population growth.

An engineering department can use Bentley OpenFlows Water to model current infrastructure and then create future demand scenarios. This helps identify areas where additional capacity may be required.

Instead of waiting until pressure problems appear, planners can evaluate infrastructure needs in advance.

New Residential and Commercial Developments

Developers and civil engineering consultants can use water distribution modeling software to verify whether a proposed development can connect successfully to an existing network.

The model can help evaluate:

• Proposed pipe sizes
• Connection points
• Pressure availability
• Storage requirements
• Future demand

This can reduce design uncertainty and improve coordination between engineers and approving authorities.

Water Utility Network Rehabilitation

Aging water systems often contain sections with insufficient capacity, high pressure, or operational limitations.

Bentley OpenFlows Water can assist utility teams in comparing rehabilitation strategies. For example, an engineer may evaluate whether replacing a pipe, adding a parallel line, or modifying valve operations provides the best improvement.

This approach can help organizations prioritize investment more effectively.

Pump Station Optimization

A utility may discover that a pump station is operating inefficiently or struggling to meet peak demand.

By modeling different pump configurations and operational scenarios, engineers can gain a clearer understanding of system performance before making expensive equipment changes.

Emergency and Failure Analysis

Water infrastructure must continue operating even when individual components fail.

Engineers can simulate conditions such as:

• A closed pipe
• Pump failure
• Tank outage
• Valve operation
• Reduced supply capacity

This supports more effective emergency planning and improves understanding of network resilience.

Performance Analysis

In professional hydraulic modeling, performance is about more than simply producing results quickly. Accuracy, model flexibility, scenario management, and the ability to handle complex infrastructure are equally important.

Bentley OpenFlows Water performs strongly in these areas.

For small and medium-sized networks, users can typically build and analyze models efficiently. Larger networks require more structured data preparation and careful model management, but the software is designed for serious engineering workloads.

A major performance advantage is the ability to evaluate multiple operating conditions. Engineers can compare scenarios rather than relying on a single simplified calculation.

The software is especially valuable when the project requires detailed analysis of:

• Complex pipe networks
• Multiple pressure zones
• Pump stations
• Storage facilities
• Variable demand
• Fire flow conditions
• Future expansion

However, the quality of the results depends heavily on the quality of the input data. A hydraulic model is only as reliable as its network geometry, elevation information, demand data, pipe characteristics, and operational assumptions.

For this reason, experienced users should always validate model results against available field information where possible.

User Experience and Learning Curve

Bentley OpenFlows Water is professional engineering software, so new users should expect a learning curve.

A beginner who has never worked with hydraulic modeling may need time to understand:

• Network model construction
• Hydraulic principles
• Boundary conditions
• Demand allocation
• Pump curves
• Scenario management
• Result interpretation

However, engineers with experience in water distribution systems will generally find the software much easier to approach.

The most effective workflow is to start with a relatively small network model. Once users understand how network elements interact, they can gradually move toward larger and more complex projects.

In practical use, the software’s greatest benefit comes when engineers use it as a decision-support tool rather than simply treating it as a calculation engine. The real value lies in asking better engineering questions and testing multiple possible solutions.
