The TEVA research program is developing several extensions to EPANET—software packages that work in conjunction with the existing EPANET and extend its capabilities. EPANET-MSX (a Multi-Species eXtension of EPANET) is a software package for modeling chemical and biological reactions in drinking water distribution systems.

Developed by EPA's Water Supply and Water Resources Division, EPANET is software that models water distribution piping systems. It is a Windows 95/98/NT/XP program that performs extended-period simulation of the hydraulic and water quality behavior within pressurized pipe networks.

Modeling Irrigation Demands

Memorial Day for many of us is the unofficial start of summer.  Summer to me means BBQ’s, bicycles and WATER.  For most utilities, water use increases dramatically during the summer months due to irrigation.  When looking at irrigation demands from a modeling perspective, there are a few issues that should be considered.  Foremost is that flow from sprinklers is pressure dependent.  Meaning that the more pressure the system experiences the higher the flow from the sprinkler.  Modeling pressure dependent demands accurately can make a big difference in your modeling and master planning efforts, especially if the majority of demands in the system you are modeling are irrigation demands, such as a reclaimed water system.    One way to resolve pressure dependant flow is to create emitter characteristics on demand junctions.
