Last updated: October 2024. EPANET 2.2 remains the current stable release. The EPA has announced work on EPANET 3.0, but no official release date has been published. For production work, stick with 2.2.
Version 2.2 introduced several critical enhancements over the legacy 2.0 series, particularly in how it handles hydraulic simulations. U.S. Environmental Protection Agency (.gov) EPANET | US EPA download epanet 2.2
: There is no native macOS EPANET 2.2. However, you can use Wineskin or CrossOver to run the Windows MSI. Alternatively, use the EPANET Python wrapper ( epanet-python ) to run simulations via the command line on macOS. Last updated: October 2024
