The Kenosha Water Utility’s Water Production Plant installed its original 14 million gallons per day (MGD) membrane filtration plant in the early 2000s, one of the first and largest municipal membrane filtration systems of its type in the country. After more than 20 years since initial start-up, most of the existing membrane filtration equipment had reached the end of its life expectancy and needed replacement. Instead of replacing the original equipment or installing an entirely new system, the Utility was able to retrofit new, updated membrane equipment into the plant’s existing process infrastructure. Not only did this represent the best overall value for the rated capacity and water quality, it also involved implementation of the newest available membrane filtration technology while minimizing both capital and maintenance costs.

This project was awarded a 2022 Engineering Project of the Year Award from the American Water Works Association (AWWA) of Wisconsin.
