Water reuse is vital and growing in popularity in America's Midwest. New systems and innovative approaches are being developed frequently. As with other parts of the US, regulatory and public perceptions can be hindrances to the implementation of these systems. In order to increase common knowledge of reuse systems, the authors of this paper are part of the newly formed Central States (Illinois, Minnesota, Wisconsin) Water Environment Association's Water Reuse Committee. Often the same factors that lead to the implementation of a reuse system in the southwest are present here too. However there are unique aspects to reuse in the north central region of the United States. This paper reviews the types of systems that are in operation and some of those that are being planned and explores the factors that drive the implementation of these projects. Includes 5 references, table, figures.
