Worthington WWTP - Secondary Treatment Plant in Greene County, Indiana

Worthington WWTP is a municipal wastewater treatment facility located in Greene County, Indiana, United States. The plant serves a population of approximately 2,415 residents, reflecting a small community-scale operation within the rural landscape of southern Indiana. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 605.66 units, and it currently discharges 605.67 units, indicating near-full utilization of its capacity. The treated effluent is discharged into local waterways that ultimately drain into the Wabash River basin, a major tributary of the Ohio River. The Wabash River supports diverse aquatic life and is an important ecological corridor in the Midwest. The plant's operation helps protect downstream water quality in this significant river system.

The plant discharges into a receiving water body that flows into the Wabash River, which then joins the Ohio River and eventually the Mississippi River. This watershed supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. The secondary treatment process reduces nutrient and organic pollutant loads, helping to maintain the ecological health of the downstream river system.
