The replacement of the Iowa Great Lakes Sanitary District Ultraviolet(UV) Disinfection System started the middle of May 2017. The project is a requirement by the 2015 NPDES permit issued by the Iowa DNR. The UV System will prevent bacteria from being able to reproduce which makes Milford Creek a safer place for people to recreate. Concrete for the new system was poured last week and the new UV system made by Trojan is schedule to be delivered during the week of June 12th. The unit will be installed and ready for testing by June 30, 2017.
