The project installed state-of-the-art equipment that uses ultraviolet light to treat raw water for bacteria and natural microorganisms that could be present in the raw water from the Mississippi River. The UV treatment equipment adds an additional treatment step to the overall water treatment process without the use of additional chemicals and is a highly effective, environmentally-friendly solution in water treatment.
