LaGrange County RUD Dist Region A is a municipal wastewater treatment facility located in Eddy, LaGrange County, Indiana, United States. The plant serves a population of approximately 1,742 residents, reflecting a small community scale typical of rural Indiana. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 454.25 thousand gallons per day and a discharge volume matching that figure, the facility operates at full capacity. As a U.S. plant, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Indiana Department of Environmental Management, ensuring compliance with effluent limits. The treated effluent is discharged into a local receiving water body, which ultimately drains into the St. Joseph River watershed and then into Lake Michigan. This connection to the Great Lakes ecosystem underscores the importance of effective treatment to protect water quality and aquatic life in the region.

The plant discharges into a tributary of the St. Joseph River, which flows into Lake Michigan, part of the Great Lakes system. This watershed supports diverse aquatic species and provides drinking water for millions. Effective secondary treatment is critical to prevent nutrient loading and protect the lake's ecological health.
