JUDA SD 1 WWTP is a municipal wastewater treatment facility located in the Town of Jefferson, Green County, Wisconsin. It serves a small population of 390 residents, reflecting its role as a local community plant in a rural setting. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater. With a designed capacity of 151.42 cubic meters per day, it operates at full capacity based on reported discharge volumes. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Wisconsin Department of Natural Resources. The treated effluent is discharged into a nearby watercourse that drains into the Pecatonica River, a tributary of the Rock River, which ultimately flows into the Mississippi River. This watershed supports diverse aquatic life and is part of the larger Upper Mississippi River Basin, an ecologically significant region for migratory birds and fish species.

The plant discharges into a local stream that flows into the Pecatonica River, part of the Rock River watershed. The Rock River joins the Mississippi River, a major continental waterway. The downstream environment includes agricultural and natural habitats that support fish, amphibians, and migratory waterfowl. The plant's secondary treatment helps protect water quality in this sensitive watershed.
