Now, Haestad Methods, a Waterbury Conn.-based water resources software company, has a new product called CivilStorm Dynamic 2005 that is capable of modeling entire city or county stormwater management systems. It can run what-if scenarios on system modifications and shock-load them with simulated storm situations. “We look at how their entire system is going to interact during a storm event,” says Gegg Herrin, product manager for storm and sanitary applications. Problem areas are quickly revealed in color-coded graphics.

The software is available at various levels of capacity, scaled to model everything from small developments to major cities. It can run as a stand-alone package or interface with a GIS database. It also interfaces with AutoCAD 2004-2005 and the federal Environmental Protection Agency’s SWMM runoff modeling system. Information is at www.haestad.com.
