ODON WWTP - Advanced Wastewater Treatment in Odon, Indiana

ODON WWTP is a municipal wastewater treatment plant located on Honey Haven Drive in Odon, Daviess County, Indiana. The facility serves a population of about 1,403 people and operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 1,059.91 million gallons per day, with an average discharge volume of 605.67 million gallons per day. As an advanced treatment facility, it likely employs processes such as biological nutrient removal or tertiary filtration to meet stringent effluent limits. The treated effluent is discharged into a local waterway that ultimately drains into the White River watershed, part of the larger Mississippi River basin. This region supports diverse aquatic life and is important for recreational activities. The plant's advanced treatment helps protect downstream water quality and ecosystems.

The plant discharges into a tributary of the White River, which flows into the Wabash River and then the Ohio River, eventually reaching the Mississippi River and the Gulf of Mexico. The watershed supports diverse aquatic species and is used for recreation. Advanced treatment at ODON WWTP reduces nutrient loading, helping to mitigate hypoxia in the Gulf of Mexico.
