The City's sanitary sewerage system is primarily designed to handle and treat domestic wastewater. After treatment at one of the City's two wastewater treatment plants, the water is clean and can then be discharged to the Red River.
The City's system is not designed to treat for many chemicals and pollutants which are contained in industrial wastewater.
Nevertheless, in many cases, the City's system can accommodate industrial wastewater which is properly "pretreated" by the industry and which meets the City's specifications and requirements.
The Pre-treatment Section of the Environmental Services Office administers the City's industrial pre-treatment program.
