SEXTONVILLE SD STP - Town of Ithaca, Wisconsin Wastewater Treatment Plant

SEXTONVILLE SD STP is a municipal wastewater treatment facility located in the Town of Ithaca, Richland County, Wisconsin. The plant serves a small population of 605 residents, providing secondary treatment to meet state and federal water quality standards. It operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. The plant's treatment process achieves secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. With a designed capacity of 238.48 units and an average daily discharge of 208.20 units, the facility operates below its maximum capacity, indicating adequate headroom for current demand. The plant's performance is monitored through regular permit compliance reporting. The treated effluent is discharged into a local waterway within the Wisconsin River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality, including aquatic habitats and recreational uses in the region.

The plant discharges into a tributary of the Wisconsin River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic life and is used for recreation. The plant's secondary treatment helps reduce nutrient loads that could contribute to downstream eutrophication in the Mississippi River basin.
