It has found widespread use in almost every aspect of urban drainage.

SWMM has undergone several upgrades since its development, the most recent one being the fifth one (EPA SWMM 5). Produced by the Water Supply and Water Resources division of the U.S. Environmental Protection Agency’s National Risk Management Research Laboratory, in a joint development effort with the consulting firm of CDM, Inc., the EPA SWMM 5, is a complete re-write of the previous release. Running under Windows, it provides an integrated environment for editing drainage area input data, running hydraulic and water quality simulations, and viewing the results in a variety of formats. These include color-coded drainage area maps, time series graphs and tables, profile plots, and statistical frequency analyses.
