LAKELAND SD 1 STP Oneida Wastewater Treatment Plant, Town of Minocqua, Wisconsin

LAKELAND SD 1 STP Oneida is a municipal wastewater treatment plant located in the Town of Minocqua, Oneida County, Wisconsin. Serving a population of about 3,200, the plant is part of the region's infrastructure for managing domestic wastewater in a rural, lake-rich area of northern Wisconsin. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Wisconsin Department of Natural Resources. For a plant of this scale, secondary treatment is the standard requirement, ensuring removal of organic matter and suspended solids before discharge. The treated effluent is released into local streams that drain into the Upper Mississippi River Basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The surrounding area features numerous lakes and wetlands, making proper treatment essential for protecting water quality and aquatic habitats.

The plant discharges into headwater streams of the Upper Mississippi River Basin, which flow through a region of interconnected lakes and wetlands. These waters support diverse aquatic life, including fish species such as walleye and musky, and provide habitat for migratory waterfowl. The downstream environment is sensitive to nutrient loading, which can affect lake water quality and recreational uses.
