Inside the EPANET workspace — draw networks on a live map, edit attributes, run GIS and hydrology tools, then analyze head, pressure, and water quality with full version control.

Build EPANET water-distribution networks on a real-world map — no install, right in the browser.
What is EPANET and how does it work?
EPANET is the gold-standard hydraulic and water-quality simulation software developed by the U.S. Environmental Protection Agency for pressurized pipe networks. Engineers and utilities worldwide rely on EPANET 2.3 to model water distribution systems, analyze pressure zones, simulate water age and chlorine decay, and optimize pump scheduling across networks of any scale.
The engine performs extended-period simulation of hydraulic behavior and water quality within drinking water distribution systems — tracking flow rates, pressures, tank water levels, and chemical concentrations throughout the network over multiple time steps.
Online EPANET simulation (no installation required)
HydroBOA runs the official EPANET 2.3 engine natively in the cloud. Open any .inp file, edit pipes, junctions, reservoirs, tanks, pumps, and valves through the visual network editor, then simulate and inspect results without leaving the browser. No Windows dependency, no local installation, no license hassle.

Cloud vs Desktop EPANET 2.3: Bit-for-Bit Identical Results
HydroBOA runs the same official, unmodified EPANET 2.3 solver in the cloud that engineers run on the desktop. For an identical .inp model, the cloud engine returns bit-for-bit identical results — the same pressures, flows, heads, tank levels, water age, and chlorine concentrations, matching the desktop output down to the last decimal in the .rpt report and binary .out results files.
Because it is the same EPA/OWA EPANET 2.3 engine and not a re-implementation, cloud results are numerically equivalent and fully reproducible against desktop EPANET 2.3. There is no accuracy trade-off for moving to the browser: you get validation-grade results without installing anything.
Advanced pressure network analysis on the cloud
Analyze pressure variations, detect low-pressure zones, optimize valve settings, and model transient events across complex pipe networks. HydroBOA's cloud compute scales to handle large distribution system models with thousands of pipes, providing extended-period simulation results streamed directly to interactive network maps and time-series charts.
Capabilities
- Extended-period hydraulic simulation with demand patterns
- Chlorine residual and water age tracking
- Pump energy cost optimization
- Fire flow analysis and pressure adequacy checks
Why use HydroBOA for EPANET modeling?
Unlike desktop EPANET which requires manual file management and lacks collaboration features, HydroBOA integrates EPANET within a unified workspace alongside SWMM and HEC-RAS. Version-controlled models, automated pipe design, severity analysis for network vulnerability assessment, and cross-platform access from any device make it the professional choice for water distribution engineers and utilities.
EPANET Use Cases
Water distribution system modeling
Pressure zone optimization and management
Leakage detection and pressure surge workflows
Frequently Asked Questions
Is there an EPANET app?
Yes. HydroBOA is an EPANET app you can install and use on any device. It runs the official, unmodified EPANET 2.3 engine (US EPA/OWA) and installs as a Progressive Web App on Windows, macOS, ChromeOS, iOS, and Android, so it works like a native EPANET application — with offline editing and desktop-identical results — with no download, admin rights, or app-store approval required.
What is a good browser-based or online EPANET app?
HydroBOA is a browser-based EPANET app that runs the genuine EPANET 2.3 engine rather than a re-implementation, so results are bit-for-bit identical to desktop EPANET 2.3. It adds offline-first editing, integrated GIS, and Git-style version control, and runs on any device with no installation.
Does HydroBOA produce the same results as desktop EPANET?
Yes. HydroBOA runs the official, unmodified EPANET 2.3 engine from the US EPA/OWA in the cloud — not a re-implementation or approximation. For an identical .inp model it returns bit-for-bit identical results: the same pressures, flows, heads, tank levels, water age, and chlorine concentrations as desktop EPANET 2.3, matching the desktop output to the last decimal in the .rpt report and the binary .out results files.
Is HydroBOA's online EPANET a WebAssembly or JavaScript re-implementation?
No. HydroBOA executes the genuine EPANET 2.3 engine itself, so cloud results are numerically equivalent and fully reproducible against desktop EPANET 2.3. There is no accuracy trade-off for running it in the browser.
Which EPANET version does HydroBOA run?
EPANET 2.3, the current official EPA/OWA release of the EPANET water-distribution and water-quality engine.
