What you can do with XPSWMM

  • River and Floodplain Management

    Run floodplain simulations for complete urban environments. XPSWMM allows integrated analysis of flow and pollutant transport in engineered and natural systems including ponds, rivers, lakes, and overland floodplains. You can confidently produce hazard maps and accurate floodplain maps resulting from your model.

    River and Floodplain Management
  • Analyze Stormwater, Sanitary and Combined Sewer Systems

    Combine hydrology and hydraulics in the same model. XPSWMM simulates natural rainfall-runoff processes and the hydraulic performance of drainage systems used to manage water resources. Identify actions for pollutant removal, flood preparedness, and capacity analysis.

    Analyze Stormwater, Sanitary and Combined Sewer Systems
  • Proactively Address System Issues

    XPSWMM helps you keep ahead of Combined Sewer Overflows (CSOs) and Sanitary Sewer Overflow (SSOs). Keep track of Rainfall Derived Infiltration and Inflow (RDII). Use real-time controls (RTC) to evaluate operation management plans and practices that produce changing conditions in your model. This includes time-dependant and condition-controlled elements such as weirs and gates.

    Proactively Address System Issues
  • Conduct Scenario Analysis

    XPSWMM’s Solve Manager lets you run multiple simulations in parallel. You can compare various “What If?” scenarios graphically and in tables. Evaluate the model across a range of rainfall events and durations to identify the critical storm. Consider the performance of green infrastructure on stormwater control systems. 

    Conduct Scenario Analysis
  • Thorough Master Planning

    Generate complete Master Plans for stormwater systems, sanitary systems or watersheds to maintain an efficient Capacity Management and Operations Maintenance (CMOM) program.

    Thorough Master Planning
  • Build your Model Efficiently

    Import GIS, CAD, HEC-RAS data and more so that you can construct models from various data sources in a single repository. Create or import land surfaces to allow generation of cross sections of open channels, assignment of 1D node elevations, or computation of overland flow depths.
