LEBANON SD 1 STP - Advanced Wastewater Treatment in Town of Lebanon, Wisconsin

LEBANON SD 1 STP is a municipal wastewater treatment facility located in the Town of Lebanon, Dodge County, Wisconsin. Serving a small population of 325 residents, the plant provides advanced treatment to protect local water quality in this rural Midwestern community. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the U.S. Clean Water Act. With a designed capacity of 136.27 million gallons per year and an actual discharge volume of 64.35 million gallons, the facility operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local waterway that ultimately drains into the Rock River basin, which flows southward to the Mississippi River. This contributes to the ecological health of the Mississippi River watershed, supporting diverse aquatic life and recreational uses downstream.

The plant discharges into a tributary of the Rock River, which flows through southern Wisconsin and northern Illinois before joining the Mississippi River. The Rock River watershed supports diverse fish populations and provides habitat for migratory waterfowl. The advanced treatment helps reduce nutrient loading, protecting downstream water quality in the Mississippi River basin.
