On the weaknesses and limitations of EPANET as regards energy

IWA PublishingGómez Sellés, E.; Cabrera Marcet, E.; Soriano Olivares, J.; Balaguer Garrigós, M. (2016 ABSTRACTWith more than 1,500 citations in ranked journals and hundreds of thousands of downloads, EPANET is the benchmark software for analysis and design of pressurised water distribution networks. User-friendly, powerful, reliable and its public domain use has spread throughout the world. However, from an energy standpoint its capacity is limited to the point where, in certain circumstances it can supply erroneous results. This is understandable because on one hand its main aim was to model water quality, and on the other hand, because it was conceived and developed towards the end of the last century before people started talking about the water-energy nexus. Increases in the cost of energy and the need to limit greenhouse gas emissions, however, have made energy efficiency a primary and inescapable objective. As the transport of pressurised water is a big consumer of energy, it seems convenient for EPANET users, particularly for those who applied this software to pressurized irrigation networks, to understand, as far as energy is concerned, its weaknesses and limitations which, at the end, is the aim of this paper.
