The Industrial treatment train is dedicated to treating wastewater flows from a paper mill located in the city. During the treatment process, solids settle out in the industrial oxidation ditches which results in large deposits that take up treatment capacity and decrease the efficiency of the treatment process on the Industrial side. To correct this issue, the City is looking to hire a contractor to clean this debris out of these tanks.

If you can not reach me, please contact Troy Zwilling (Water/Wastewater Supervisor) at 320-428-5779 for assistance.
