Water distribution modeling with hydraulics, quality, cost, and operations in the loop. ConduitNET stands on EPA EPANET and operates above it, adding conceptual modeling features that make rich EPANET models faster to build. Real utilities anchored to real coordinates and real demand patterns, or synthetic conceptual models for testing and instantly running the global EPANET community's existing library — both first-class.
Two complementary pillars. Start with tutorials for the full workflow. Dive into Realtime Help for concepts, methods, and reference.
Two-way enrichment with EPA EPANET. ConduitNET models live as standard EPANET .INP files — yours exports out, theirs loads in. The bridge is more than file compatibility: ConduitNET adds a conceptual modeling layer above EPANET — visual network configuration, a suite of predefined storage units (tanks and towers; above-ground, below-ground, elevated — each with its own cost implications), conceptual valve and pump arrangements, water quality scenarios. Load a basic EPANET model, enrich it inside ConduitNET, save it back as a richer EPANET file. Synthetic mode is the entry point for legacy files; geo-referenced mode anchors new models to real data.
Cost in the loop. ConduitNET ships with a first-class, physics-based, bottom-up cost engine — not a spreadsheet add-on. Pipes, junctions, the full storage suite (tanks and towers; above-ground, below-ground, elevated — each with its own cost implications), pumps, valves, treatment, service connections — all costed together. Run cost analysis before or after simulation; iterate alternatives in the same view. See the cost model methodology →
Step-by-step walkthroughs for building water distribution models in ConduitNET — from synthetic examples to real geo-referenced networks.
Realtime Help is more than a reference library — it's the knowledge layer of the platform. Modeling concepts, governing science, numerical methods, per-element operational help, visualization guidance, and the foundational engine references — organized hierarchically so you can stop at any depth and still have what you need. Especially deep on pressurized network behavior, demand patterns, water quality, the storage suite (tanks and towers, above/below/elevated), the EPANET input grammar, and the bottom-up location-aware cost engine.
ConduitNET is built on EPA EPANET — the international standard for water distribution network modeling. These authoritative references cover hydraulic analysis, single-species water quality, advanced multi-species reactive transport, and programmer toolkits, all hosted by the U.S. Environmental Protection Agency.
