HydroSewer - Drainage Network

About HydroSewer - Drainage Network

HydroSewer is a professional stormwater and sewer network analysis tool powered by the EPA SWMM 5.2 engine. Design, analyze, and simulate drainage networks directly from your phone.

KEY FEATURES

- Import and export EPA SWMM input files (.inp) for full compatibility with existing workflows
- Run hydraulic simulations using the real EPA SWMM 5.2 engine — no cloud required, everything runs on-device
- Visualize your drainage network with an interactive map: zoom, pan, and select elements
- Step through simulation results over time to see how your network performs under storm conditions
- Inspect and edit node, link, and subcatchment properties
- View real-time computed values: water depth at nodes, flow rate in conduits, velocity, and more

BUILT FOR ENGINEERS

HydroSewer brings the power of EPA SWMM to your mobile device. Whether you're in the office reviewing a design or in the field verifying a network, you can load any standard .inp file and run a full dynamic simulation instantly.

Supported elements include junctions, outfalls, conduits, pumps, weirs, orifices, subcatchments, and rain gages.
