The Monroe Wastewater Utility is an enterprise fund of the City of Monroe. The Utility provides wastewater collection and treatment services to approximately 4,400 properties within the City. Financial accounting for the Utility is managed by the Utilities Finance and Budget Director.

The Wastewater Utility operates under the environmental regulations of the Wisconsin Department of Natural Resources, and service rules of the Monroe Common Council. Utility rates are established by the City of Monroe.

The Utility operates and maintains the waste treatment plant, and conveyance system. The plant can processes up to 3.7 million gallons of waste water each day, treat 15,000 pounds of Bio-chemical Oxygen Demand, and 7,600 pounds of Total Suspended Solids. As it returns water to Honey Creek, it is consistently cleaner than the creek water itself. 

Over the years, the City of Monroe has made several improvements to its Wastewater Treatment Facility. During 1984, the City of Monroe upgraded to an Advanced Secondary Treatment Facility. In 1991, a 1,500,000 gallon equalization facility was added. During 1999, a Chemical Phosphorus Removal System was added. Currently, construction has begun to rehabilitate the plant processes, as the capacity and ability to treat the loadings, have surpassed its’ design.

The collection system is made up of 5 lift stations, and approximately 70 miles, or 370,000 feet of pipe. The majority of the collection system piping is 6” pipe. The aging infrastructure is the largest concern for reinvestment. Any improvements made in to the collection system will ultimately ease the demand on the pumps, processes, and the plant.

Wastewater Treatment Plant Upgrade & Alterations
The Wastewater Treatment Plant is currently undergoing a massive upgrade that started in May 2013. The project, which is upgrading a significant amount of the plant’s aging infrastructure and equipment as well as improving its capacity, is slated to cost upwards of $25 million dollars. The project is largely being funded by the Utility through a Clean Water Fund loan. Miron Construction, the primary contractor on the project, submits photos every month to the project engineers representing the City. Follow the link to view well over one hundred photos of the project since May, including a pre-construction video walk through of the plant. The project will continue on through 2014 and conclude in early 2015.  Photos
