Sewer Utility

Summary​

The City’s waste water is treated at the Nine Springs Waste water Plant located at 1610 Moorland Road, approximately one mile south of Lake Monona.  Highly treated effluent is then pumped nine miles back to the west where it outfalls into the headwaters of the Badger Mill Creek just east of the City.  Pump Station # 17 and the force main became operational on July 2, 1996 conveying all of the City’s waste water to the Nine Springs Waste water Plant which is owned and operated by Madison Metropolitan Sewerage District.  On August 10, 1998, the District began operating the Badger Mill Creek Effluent Return Project which is owned and operated by Madison Metropolitan Sewerage District. Currently, approximately three million gallons per day of highly treated effluent are pumped into the Badger Mill Creek.  The Utility is a self supporting enterprise; 100% of the Sewer Utility expenses are supported through Sewer Utility rates paid by its customers.    

The Sewer Utility is responsible for serving approximately 4,700 customers by maintaining approximately 73 miles of sanitary sewer mains ranging in size from 4 inches to 15 inches in diameter. The City maintains two pump stations.  One is located on Epic Lane which serves the Epic Campus and a portion of the Westridge subdivision.  The second one is located on Locust Dr. and it serves the Scenic Ridge subdivision. All of the remaining collection flows by gravity to Pump Station # 17, which is owned and operated by MMSD.  Currently, approximately 330million gallons of wastewater per year is conveyed to the Nine Springs Waste water Plant to be treated at a cost of approximately $1,250,000 in 2020.
