MS4 Program       BePartoftheSolution

What is an MS4?
MS4 stands for Municipal Separate Storm Sewer System. An MS4 entity owns or operates a system for collecting and conveying stormwater. The purpose of the MS4 program is to maintain and benefit water quality in creeks, streams, and waterways by reducing pollutants in stormwater runoff. Click here for more information about the program.


The City of Valparaiso's MS4 program was recognized by Indiana Department of Environmental Management (IDEM) at the 2013, 2014 and 2015 MS4 Annual Meetings for multiple categories, including illicit discharge detection and elimination, post-construction stormwater runoff control, public education/participation through rain barrel decorating competition, stormwater management utilizing trees, and programs and projects that are beyond the MS4 Stormwater Quality Management Plan. Click
