This is a Full Membership for the 45 Phase I and II Iowa communities that are required, by law, to have an NPDES Permit for stormwater management. These cities and universities are the reason this program was developed. So far, 32 communities have joined the ISWEP program and come to realize the convenience and economic benefit of its resources.
