StormNET® is the leading software for analyzing and designing urban drainage systems, stormwater sewers, and sanitary sewers. It includes a range of features and capabilities that make it faster, simpler to use, and more accurate. StormNET is used by over 3,000 companies worldwide such as URS, Jacobs, Tetra Tech, HNTB, ARCADIS, and Stantec.

Civil 3D Drainage Hydrology Extension

StormNET for Civil 3D operates within AutoCAD Civil 3D as a native Civil 3D extension. StormNET for Civil 3D will perform:

  • Stormwater drainage, hydrology, and hydraulic analysis
  • Stormwater sewer pipe sizing
  • Storm drain gutter spread analysis
  • Detention pond sizing and outlet design
  • Sanitary sewer pipe network design
  • Additional Civil 3D support tools

Change a roadway alignment or surface grade elevation, and have your manholes, storm drains, and sewer pipes automatically update to reflect the change. Grab a storm drain or manhole, move it to another location on your site plan, and have the rim elevations, sump elevations, and connecting sewer pipes automatically update.

Full functionality and integration within AutoCAD Civil 3D increases your productivity, reduces your engineering work, saves time, and decreases costs. This sophisticated level of stormwater engineering integration within the AutoCAD Civil 3D environment greatly increases your productivity.

Civil 3D Parts

StormNET for Civil 3D includes all of the necessary parts for designing your stormwater and sanitary sewer pipe network, including FHWA storm drain inlets. These parts automatically integrate into your Civil 3D Parts Catalog, without requiring the use of the Civil 3D Parts Builder.
