Stormwater Management / Sanitary / Combined Sewer Remediation

To streamline the design effort involved in meeting US EPA regulations, including NPDES permits, CMOM, and/or TMDL requirements, PCSWMM provides an efficient set of tools for designing stormwater management control strategies for minimizing combined sewer overflows (CSO), sanitary sewer overflows (SSO), water in basements (WIB), surcharging, street flooding and/or rainfall-dependent inflow and infiltration (RDII). Powerful importing, QA/QC, and network building tools significantly reduce the development time for large models.

• Model with as much detail as necessary, with optimized performance for large system wide models (100,000+ pipes/nodes)
• Simulate valves, gates, inflatable dams, leaping weirs, and other complex flow structures
• Accurately model force mains, lift stations and pumps
• Account for seasonal and event-based groundwater interflow
• Easily import data from all common GIS, CAD, database, spreadsheet formats
• Quickly convert existing older EPA SWMM models to SWMM5
• Automate network construction from imported data
• Quickly perform comprehensive QA/QC on imported data
• Data entry error checking, advanced error detection and consistency checks
• Fill in missing values with a wide range of estimators
• Estimate model parameters from spatial GIS data with powerful topological operations (area-weighting, spatial allocation, etc)
• Quickly calibrate any/all model parameters with the exclusive, intuitive Sensitivity-based Radio Tuning Calibration (SRTC) tool
• Simplify diurnal and seasonal dry weather flow (DWF) pattern creation with specialized tools and allocate loads and patterns with fast topological operations
• Quickly determine and assign DWF loadings from lot level water usage data
• Automate RDII unit hydrograph development with a unique, straightforward RDII calibration process
• Model dynamic storms with high spatial and temporal variations in rainfall with rain-gage calibrated radar-rainfall
• Optimize system storage and operation with global optimal (GO-RTC) and passive real-time control modeling
• Assess the impact of multiple Low Impact Development (LID) practices on storm sewer relief
• Check capacity requirements for compliance
• Quickly perform comparative analyses of different "what-if" strategies with comprehensive scenario analysis graphs, profiles and reports
• Easily create sub models for detailed studies, and update the macro model when completed
• Keep track of all related documents, photographs, videos, etc. through geo-referenced points of interest (POIs) and the project notes manager
• Easily assign and visualize confidence levels for all model parameters
• Project model results and animations in Google Earth for client presentations
