One tool for what used to take several — and a browser for all the hardware you need.
In short — ORCANET is a web platform for hydraulic simulation of drinking-water networks. Its solver uses the EPANET 2.2 method and gives the same results to within 1 cm; it runs in the browser, with nothing to install.
Global gradient solver, validated and robust: Hazen-Williams, Darcy-Weisbach, Chezy-Manning.
Extended period over 24 h and beyond: demand peaks, tank filling, automatic controls.
Least-cost sizing, pumping schedule and leak reduction — without guesswork.
Automatically fit the model to your field measurements: a true digital twin.
Residual chlorine, water age, source tracing and multi-species reactions (MSX).
Consumption, pumping cost and specific energy (kWh/m³): control your bill.
A copilot that understands your network, explains the results and guides you to the solution.
Draw your network on a real satellite basemap: lengths and elevations captured automatically.
Laid-out PDF deliverables, CSV exports and standard formats — ready to share.
Import your .inp and your existing projects — structure, options and curves included. You pick up exactly where you left off.
Yes. ORCANET runs entirely in the browser: open a free account, import an EPANET .inp file or draw the network, then run the calculation. Hydraulic and water-quality simulation run on your own computer, without sending anything to a server; a 24-hour run on 2,500 nodes takes less than a second.
It is a series of hydraulic calculations over a period — typically 24 hours — during which demand varies with demand patterns and tanks fill and empty. It shows what a steady-state run hides: the peak hour, tank level swings, pumping cycles and water residence time.
The water-quality module carries each substance along the pipes and applies its reactions: chlorine decay in the bulk water and at the pipe wall, water age, source tracing. For several species reacting with each other, a multi-species module equivalent to EPANET-MSX is built in. This shows where residual chlorine becomes insufficient.
The three formulas of the EPANET standard: Hazen-Williams, Darcy-Weisbach and Chézy-Manning, in SI and US units. Minor losses in bends, valves and fittings are added through coefficients. An imported model therefore keeps its original formula and coefficients, with no conversion.
