Key features of XPSWMM

River and floodplain management

Simulate urban floodplains. Analyze flow and pollutant transport and create accurate hazard maps.

Combine hydrology and hydraulics

Analyze stormwater and sanitary and combined sewer systems. Simulate runoff, drainage, and pollutants.

Proactively address system issues

Manage CSOs and SSOs, track infiltration and inflow, and use real-time controls.

Conduct scenario analysis

Run parallel simulations, compare scenarios, evaluate rainfall events, and assess green infrastructure.

Thorough capital planning

Maintain efficient capacity management programs for watersheds or stormwater and sanitary systems.

Efficient modeling

Import GIS, CAD, and HEC-RAS data. Create/import land surfaces, generate cross sections, and compute flow.
