Criticality Analysis Technical Preview
This feature lets utilities identify high-risk pipes proactively, supporting data-driven maintenance and investment decisions. This feature lets utilities understand the network isolation valve coverage and the corresponding consequence of failure of pipes and valves, supporting data-driven maintenance and investment decisions. It incorporates system valve locations to process all isolation areas within the network, including impacted customers and hydraulic attributes for each area. It also offers more flexibility and user input options than previous solutions. To learn more, explore Criticality Analysis
This feature is released as a technical preview. Parts of the analysis are still being worked on for future releases. Learn more about Technical Preview
New Fire Flow Conditions Report
The Fireflow Conditions report is a new feature in fire flow analysis that simplifies reading and interpreting results. It organizes data by condition—Static, Required, Available, and Design—which you can select from a drop-down menu. The Design condition appears only if chosen during analysis. By grouping results by condition and keeping a consistent layout, this report clearly links variables to their conditions and network elements, enhancing clarity and reducing cross-referencing.

New Fire Flow Capacity result field for Map Themes
Hydrant Capacity Excess/Deficit is a new fire flow result field, introduced in the Fire Flow Conditions report. It is now available in Map Themes as a clear indicator of capacity versus failure at each hydrant node relative to its required flow.
Hydrant lateral velocity constraint
Most models omit small lateral pipes to hydrants. However, you may need fire flow calculations reflecting realistic limits at these points. Now, you can set the diameter of “virtual” hydrant laterals and a maximum velocity limit, ensuring flows match what the lateral pipe can deliver, even if pressure allows more. This update improves fire flow accuracy without detailed lateral modeling, helping spot and fix excessive velocities at hydrant connections for safer, realistic results.
New Modified Hazen-Williams Roughness equation
We've introduced a new Roughness Equation to the Simulation Options. When selected, this equation interprets pipe roughness as the modified Hazen–Williams roughness coefficient, CR, which is normalized to 1 for smooth pipes and decreases as pipe roughness increases.
New Water Quality Simulation type: Reverse trace
We've added a new simulation type for water quality. It is similar to Source Trace, but instead it calculates the percentage of water exiting downstream through or stopping at the selected Trace Node instead of tracing the origin. This forward-looking analysis is computed backward in time, enabling evaluation of capacity constraints for large flows or identification of contaminant sources.
The Enhanced Low Flow method is now optional
We've added the option to enable or disable Enhanced Near-Zero Flow Handling and the Accelerated Design Fire Flow Solver, giving you more flexibility when running simulations. The basic approximation method from EPANET 2.3 works well in most cases and is always applied. Headloss calculations are generally more accurate with the enhanced treatment, although it may slightly slow convergence. Select Enhanced Near-Zero Flow Handling to supplement the basic EPANET approach.
Better control over sequence visualization in Flush Sequence Manager
The Flush Sequence Manager displays all valves that are operated (opened or closed) during the current sequence. Additionally, it can show valves that were closed in previous sequences and remain closed. These previously closed valves are indicated with a distinct symbol color, which can be configured in the UDF options. For each sequence, you can choose whether to display these operational valves, providing greater flexibility and control over sequence visualization. Learn more about Flush Sequence Manager
