RIDGEVILLE WWTP - Secondary Wastewater Treatment Plant in Ridgeville, Indiana

RIDGEVILLE WWTP is a municipal wastewater treatment facility located on East Main Street in Ridgeville, Randolph County, Indiana. The plant serves a small population of 814 residents, providing secondary treatment to manage domestic wastewater from the community. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal facilities. With a designed capacity of 378.54 cubic meters per day and a discharge volume matching that capacity, the plant is operating at full capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into a local waterway, likely a tributary of the Mississinewa River or the Wabash River basin. The plant plays a key role in protecting downstream water quality in the Wabash River watershed, which drains into the Ohio River and ultimately the Mississippi River. Proper treatment helps maintain aquatic ecosystem health in this agricultural region.

The plant discharges into a receiving water body within the Wabash River basin, which flows into the Ohio River and then the Mississippi River. The watershed supports diverse aquatic life and is an important migratory corridor for fish species. Secondary treatment reduces nutrient and organic loads, helping to prevent eutrophication in downstream rivers and lakes.
