Chalmers Town of Wastewater Treatment Plant, Brookston, Indiana

The Chalmers Town of wastewater treatment plant is located on SR 43 in Brookston, White County, Indiana. Serving a population of approximately 600 residents, this facility is a small municipal plant that plays a vital role in managing local wastewater in the rural agricultural landscape of northwestern Indiana. As a secondary treatment plant, it employs biological processes to break down organic matter, meeting the standard requirements for municipal wastewater treatment in the United States. The plant has a designed capacity of 340.69 megaliters and currently discharges 227.13 megaliters annually, indicating operational headroom. Under the US Clean Water Act, such facilities must obtain NPDES permits that set effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Wabash River basin, a major tributary of the Ohio River. This watershed supports diverse aquatic life and is important for regional agriculture and recreation. The plant's operations help maintain the ecological health of these receiving waters.

The plant discharges into streams within the Wabash River watershed, which flows into the Ohio River and ultimately the Mississippi River. This basin supports a variety of fish and wildlife, including several species of freshwater mussels. The region's flat terrain and agricultural land use mean that nutrient management is a key concern for downstream water quality.
