EPANET Plus is a powerful tool for water distribution system analysis and design, offering a wide range of features and applications. Its ability to simulate hydraulic and water quality behavior, optimize system operations, and integrate with GIS makes it an essential software package for water utilities and engineers. As the demand for safe and reliable drinking water continues to grow, EPANET Plus will play an increasingly important role in helping to design and operate efficient, sustainable, and resilient water distribution systems.
Water distribution systems are the invisible backbones of modern cities. For decades, hydraulic engineers have relied on EPANET—the open-source software developed by the U.S. Environmental Protection Agency (EPA)—to simulate piped water networks. While the original EPANET engine remains a masterpiece of computational hydraulics, its native user interface and workflow capabilities have lagged behind modern software standards.
Several software developers offer versions of EPANET Plus, often branded under different names like WaterGEMS, InfoWater, or specialized open-source distributions. When selecting a version, consider the following:
architecture, EPANET-PLUS allows for the same robust analysis found in the standard version, but with greater flexibility for customization: GitHub - WaterFutures/EPANET-PLUS epanet plus

Do you need to integrate this with or AutoCAD ?
Modern systems require efficiency. EPANET Plus tools often incorporate to help engineers: Minimize pumping energy costs. Optimize pipe diameters for new developments. Water distribution systems are the invisible backbones of
: It enables you to integrate EPANET simulations into other web or desktop applications through a REST API, extending its use beyond just a desktop modeling tool.
A modern, cloud-based digital twin platform that simplifies the EPANET workflow into an intuitive, lightweight web interface for operators.
The OWA community is responsible for the most significant engine upgrades in years, including the release of in July 2025, which has been further refined with subsequent patches (2.3.4 as of February 2026). This collaborative model has sparked the creation of a rich ecosystem of tools built on the EPANET engine.
