The City of Winona Wastewater Treatment Plant serves the needs of the City of Winona and also of the City of Goodview. From 1997 – 1999, the plant was upgraded at a cost of approximately $5 million. The current plant has a design capacity of 9.6 MGD (million gallons per day), which allows room for current and future expansion. Winona’s Wastewater Treatment Plant utilizes a trickling filter with activated sludge system to process influent. Treated sludge and wastewater are then discharged in accordance with the Plant’s permit. Some of the industries in Winona have large discharge requirements which do not fit the standard profile for smaller dischargers. These customers are served through special agreements with the Industrial Pre-Treatment area which allow handling these special discharges without compromising the operation of the plant.

Frequently Asked Questions:

What should I do when my sewer is backing up?

The first thing you should do when the sewer is backing up in your facility is call the sewer department at 457-8207. If there is no response at that number call the Law Enforcement Center at 454-6100 and they will call out a crew to the address.

Can sewer gas enter my home from the City sewer lines?

Sewer gas can enter a building when the water in a trap in the building evaporates. All fixtures that are connected to the sewer system must have traps on them. The water that is normally retained in the trap forms a barrier to the migration of gases.

I am not sure I should sewer this material. What should I do?

Never sewer anything that is highly flammable or explosive. Never allow mercury, or other toxic materials, to enter the sewer. Most potentially dangerous chemicals have labels, Material Safety Data Sheets, or accompanying literature that states whether or not the material is sewerable. Follow those instructions when they are given.

If the literature advises you to call the local sewer authority for permission to sewer a given material, please call us at 457-8207.

If there is any question in your mind as to whether or not you should sewer something, do not sewer the material without talking to us first. Thinking carefully before sewering materials will help to protect public safety, prevent upsets at the Wastewater Treatment Plant, and protect the water quality of the Mississippi River. Think about the potential danger of sewering a substance that will produce a dangerous gas in light of the fact that the atmosphere in the City sewer lines can migrate into facilities under certain conditions.
