Table comparing and contrasting the features of the Storm Water Management Model (SWMM5) and the EPANET Water Distribution System (WDS)

Feature	SWMM5	EPANET
Subcatchments	Subcatchments represent the land area that contributes runoff to a stormwater system. They can be specified by size, slope, and land use.	Junctions represent the points where pipes connect in a distribution system. They can be specified by demand and elevation.
Links	Links model the flow of water through a stormwater system. They can be specified by size, material, and roughness coefficient.	Pipes model the flow of water through a distribution system. They can be specified by size, material, and roughness coefficient.
Junctions	Junctions model the points where links connect in a stormwater system. They can be specified by elevation and initial water depth.	Junctions model the points where pipes connect in a distribution system. They can be specified by demand and elevation.
Outfalls	Outfalls model the points where water leaves a stormwater system, such as a stream or river. They can be specified by type and discharge coefficient.	Valves are used to control the flow of water in a distribution system. They can be specified by type and setting.
Storage	Storage models the volume of water that can be stored in a stormwater system. It can be specified by size, shape, and initial water depth.	Reservoirs and tanks are used to model water storage in a distribution system. They can be specified by size and initial water level.
Infiltration	Infiltration models the infiltration of water into the ground,

Innovyze Announces Worldwide Support for EPANET and SWMM

Groundbreaking Initiative Facilitates Technology Transfer of Sustainable Water Infrastructure Models Between Global Communities

Broomfield, Colorado, USA, March 31, 2015

Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced worldwide support for USEPA’s flagship EPANET and SWMM public domain software. By offering its technical expertise to the EPANETand SWMM communities, Innovyze is ensuring ongoing maintenance of these free software models of sustainable stormwater, wastewater, and water supply systems.

Sustainable water infrastructure models are used throughout the world for the planning, analysis, design, and research of stormwater, wastewater, and drinking water distribution management. SWMM can model the generation and transport of runoff and sanitary flows as well as estimate the production of pollutant loads associated with this runoff in storm, sanitary or combined sewers. With the recent inclusion of hydrologic performance of specific types of green infrastructure low impact development (LID) controls the model can be used to consider both grey infrastructure approaches (e.g., pipes, tunnels, high rate treatment), and potentially more cost-effective green infrastructure approaches (e.g., rain gardens, permeable pavement, rain barrels) for managing stormwater. EPANET can help water utilities maintain and improve the quality of water delivered to consumers through their drinking water distribution systems. It can also be used to plan and improve a system’s hydraulic performance. The model can assist with pipe, pump, and valve placement; sizing; energy minimization; fire flow analysis; vulnerability studies; and operator training. Together, these models give municipalities the tools to help them develop cost effective green and grey water infrastructure options that reduce the release of untreated wastewater and improve the availability of safe drinking water.

“Innovyze is a pioneer in cutting edge sustainable water infrastructure modeling research and development,” said Paul F. Boulos, Ph.D., BCEEM, NAE, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “The company’s industry-leading GIS-centric InfoWater and InfoSWMM product suites greatly expand on the simulation and analysis capabilities ofEPANET and SWMM5 models. Ongoing maintenance of EPANET and SWMM is important both to us and to the global water and wastewater communities. It ensures the usefulness and longevity of these products for their users. We are pleased to launch this initiative to help further sustain the world’s wet infrastructures and provide solutions to such challenging problems as climate change, water security, and environmental compliance.

“We hope to continue to inspire water modelers worldwide and provide them the power tools to do the things that inspire them so that together we can build and sustain resilient water infrastructures that help drive the economy and create a better world for everyone.”
