Characteristics

Flexible, smart GIS engine

PCSWMM EU incorporates a modern, powerful GIS engine that works seamlessly with the latest GIS data formats, and provides intelligent tools for streamlining model development, optimization and analysis in a comprehensive range of applications.

With full support for the latest, fully dynamic US EPA SWMM5 hydrology/hydraulics engine, PCSWMM provides a scalable (unlimited model sizes), and complete array of stormwater management, wastewater and watershed system modeling tools for an affordable price.

PCSWMM EU is the most powerful urban drainage modeling application for working with GIS/CAD based data. PCSWMM enables both engineers and GIS professionals to work on the same data, improving workflow and collaboration. PCSWMM supports the leading open standard and proprietary GIS and CAD formats, including ArcGIS, Geomedia SQL, MapInfo, Microstation, AutoCAD, GML, OpenGIS SQL, KML and many others (over 30 vector and raster formats supported), giving you the option to work with whichever file formats are required, greatly increasing the flexibility of both your model building and analysis toolset.

PCSWMM’s high-performance, scalable GIS engine provides powerful GIS analysis and hydraulic modeling in a single stand-alone environment, with no other third-party licenses required. You can create, edit, modify, run, map, analyze, design and optimize your GIS based sewer network models and instantly review, query and display simulation results either from within the optimized PCSWMM interface or from within Google Earth, ArcGIS, or the GIS of your choice – its up to you.

PCSWMM automatically maintains a standard, fully accessible US EPA SWMM5 input file at all times. Support is provided for using other SWMM5 data editors (e.g. US EPA SWMM5 interface, or in-house tools), as edits to the input file are detected and the SWMM model GIS layers are automatically updated.

PCSWMM EU provides direct support for opening, editing, running, plotting and analyzing any existing SWMM5 models, as well as importing/converting SWMM4 models.

PCSWMM EU is a fully featured urban drainage system modeling package, with no limitations on model size or complexity, totally adapted for the European context.

PCSWMM EU contains a complete GIS system (no third party software required) tailored to urban drainage modeling which supports most projections, datums, and ellipsoids, provides interaction with a large number of GIS formats, as well as topological operations and querying.

PCSWMM EU provides advanced versions of all of the standard urban drainage modeling visualization techniques, including animated hydraulic grade line and energy grade line profiles, plan-view static and temporal thematic rendering, powerful plotting tools, as well as on-the-fly statistical and error analysis.

PCSWMM EU automatically maintains standard US EPA SWMM5 models from GIS data and synchronizes in both directions, thus providing complete data compatibility with any other SWMM5 GUI (including the US EPA GUI).
