The EPANET program and source code have played invaluable roles in research and practice in the WDSA field. The undersigned supporters of the Open Source EPANET initiative acknowledge the visionary role of the US EPA in developing EPANET and placing the program and source code in the public domain.
The WDSA Standing Committee of the EWRI (Environmental and Water Resources Institute), a technical institute of the ASCE (American Society of Civil Engineers), voted to initiate an open source project for the continued development of EPANET. This project will initially be supported by the WDSA Standing Committee and its officers, but it will be owned and managed by the wider WDSA community without affiliation to any private or public for-profit institution or company.
The initiative is supported by a long list of researchers, engineers, developers, and practitioners including the creator of EPANET, Dr. Lew Rossman.
