The City of Valparaiso's MS4 program was recognized by Indiana Department of Environmental Management (IDEM) at the 2013 MS4 Annual Meeting for three categories, including efforts to detect and eliminate illicit discharges, efforts to control post-construction stormwater runoff, and public education/participation for the recent rain barrel decorating competition.

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.

News on 2014 Rain Barrel Program
The quota for subsidized rain barrels this year has been met, so the City of Valparaiso will not accept any more orders. You can still order rain barrels and accessories through Porter County's rain barrel program from this link.
Pick up for orders placed though the City of Valparaiso will be at Central Park Plaza, 63 Lafayette St, Valparaiso, IN 46383, on May 31st between 10 am and 2 pm. Paid receipt is required to verify purchase information when orders are picked up.

If you are unable to pick up your rain barrel at the pickup time, please arrange for your barrel to be picked up by a friend, relative, neighbor, etc. We are unable to store unclaimed barrels at our office.

Thank you all for your interest in our rain barrel program!
