The Hydraulics and Hydrology development team has released OpenFlows Storm 2026 (26.00.00.514) is a multiplatform hydraulic and hydrologic modeling solution developed for engineers to analyze complex stormwater systems, improve pond design, and gain workflow efficiency. Detect system bottlenecks, improve capacity, and limit stormwater flooding to comply with regulations.
A new version of OpenFlows Storm (StormCAD and CivilStorm). Note that PondPack is part of OpenFlows Storm but has not been updated with this release.
IMPORTANT: this was initially released as version number 26.00.00.508 on May 7th 2026, then subsequently re-released to fix an issue with background maps and deployment images. The official released build is 26.00.00.514 (May 19th, 2026).

OpenFlows Storm is the first and only fully-dynamic,multi-platform (GIS, CAD, and Stand-Alone) sanitary and combined sewer modelingsolution. With CivilStorm , you will analyze all sanitary and combinedsewer system elements in one package and have the option of performing theanalyses with the SWMM algorithm or our own implicit solution of the full SaintVenant equations. Simply put, CivilStorm offers the most comprehensive solutionavailable for optimizing Best Management Practice (BMP) designs and meetingsanitary sewer overflow (SSO) and combined sewer overflow (CSO) regulations.
