Home / About ISWEP


U.S. Environmental Protection Agency MS-4 stormwater regulatory requirements prompted our founding in 2005. Since our founding, the goal of the Iowa Stormwater Management Partnership (ISWEP) is twofold: Support compliant and effective local stormwater management programs with unified education and outreach delivered statewide.


The majority of MS-4 cities and universities in Iowa are members of the organization. Numerous non MS-4 cities have found ISWEP valuable in developing their stormwater management programs. And we are also supported by professional consultant and engineering firms.

Non-Profit Organization

In January of 2016 the Iowa Stormwater Education Parternship became a registered 501(c)(3) non-profit organization.
