The Red Wing Municipal Wastewater Treatment Plant has a biological system that can be harmed if improper substances are discharged into the sewer. To protect the facility, the City has enacted a Significant Industrial User Ordinance that puts the responsibility of these discharges on the industries generating the waste. This applies to one-time discharges as well as continual industrial strength discharges. All businesses and industries must apply for a discharge permit through the Utilities Office at the Public Works Building. All industrial/commercial wastes will be analyzed to determine potential problem wastes. In some cases, industrial wastewater is required to undergo pretreatment prior to discharged into the system.
