The whole list
What it does
Everything here works in a browser, free, with no account.
This list is long and detailed, but incomplete. Use your browser’s find (Ctrl+F, or ⌘F on a Mac) to search for a feature you are interested in. If you only want to know whether the thing is any good, diving in saves time.
37 things it does.
The extensions 9
| Scenarios: each one holds only its overrides of the base model, with an override report and a scenario comparison report. |
| World map canvas, street or satellite, or your own backdrop with friendly positioning options. |
| Fire flow analysis across the whole system, reporting where the required flow fails and where it pulls pressure below design elsewhere. |
| Customers: metered services with demand, service count, and pattern, each connected to the node or pipe that serves it. |
| Custom properties on any kind of asset, with your own labels and limits, overridable by a scenario, and flagged in place when a value breaks its own limits. |
| Pipe types library: one “150 mm PVC” definition that many pipes refer to, so editing the definition edits every pipe using it. Detach one pipe when it needs to be the exception. |
| Fittings library: a pipe’s minor loss summed from named fittings and their quantities, starting from the EPANET user manual’s own table and editable. |
| Import whole libraries from another project file. A name already taken is skipped and listed, so nothing you have is changed. |
| Group edit three ways: find and replace, select an area, or edit the tables like a spreadsheet. |
Solver 3
| The EPANET 2.3.5 engine, running in your browser, for steady state and extended-period simulation. |
| A built-in solver of our own for a single moment, and a display comparing the two. |
| Recalculate automatically, or only when you ask. |
Projects and saving 2
| Several projects open in tabs, kept in your browser, or saved to a project file with locking for sharing on an office network. |
| Install for offline use. |
Import, export, and map 4
EPANET .inp files import and export, with a report of everything accepted or ignored, and unedited values written back character for character. |
| Examples from EPANET and others, on XY and on latitude and longitude, loaded and solved in one click. |
| An import wizard that moves an XY model onto the world map. |
| Place-name search, and ground elevations read from the map’s terrain data with a preview. |
Assets and results 8
| Junction, reservoir, tank, pipe with vertex drawing and editing, pump, valve, customer, and annotation text. |
| Node and link labels built from several fields, with prefixes, suffixes, a separator, and a drop order, placed automatically or by hand on leaders or along links. |
| Find, replace, and go to elements, including compound queries in your language. |
| Editable, pasteable, spreadsheet-like tables for every kind of asset. |
| Network coloring: three to seven ranges, eight ways of choosing where the breaks fall, and 41 color ramps. |
| Multi-line annotation text with bold, rotation that can match a pipe, and association to an asset. |
| Separate size settings for text, symbols, and pipes. |
| Hydraulic grade line profiles along a path you choose and edit. |
Extended-period simulation 8
| Patterns for demands, reservoir head, and pump speed. |
| Simple controls and EPANET-style rule-based controls. |
| Pump, efficiency, head loss, and tank volume curves, defined once in the Libraries box and referred to by name, so a manufacturer’s curve keeps every point it was published with. |
| Playback of the run, step by step or animated. |
| The EPANET run report, including every element at every time step and what switched, and when. |
| Color limits held constant through a run, so a color means the same thing at every step. |
| Water quality: age, share from a source, chemical decay. |
| Pump energy: run time, power, and cost including a peak demand charge. |
Language, license, and privacy 3
| Twenty-seven languages, and every word is evaluated for translation. |
| Free software under the GNU GPL, source in the open. |
| No account, no visitor identifier, and nothing counted about you unless you say yes. |
