New Richmond WWTP - Secondary Treatment Plant in Montgomery County, Indiana

New Richmond WWTP is a municipal wastewater treatment facility located in Montgomery County, Indiana, United States. The plant serves a small population of 345 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids from wastewater. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. For small communities like this, secondary treatment is the standard requirement to protect water quality. The plant's designed capacity is 151.42 cubic meters per day, matching its current discharge volume. The treated effluent is discharged into a local water body, likely a tributary of the Wabash River basin. The Wabash River flows southwest to the Ohio River, which joins the Mississippi River and ultimately reaches the Gulf of Mexico. This downstream connection highlights the importance of effective treatment in protecting aquatic ecosystems and downstream water quality.

The plant's discharge enters a local stream within the Wabash River watershed, which drains into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. The Wabash River supports diverse aquatic life, including fish species such as catfish and bass, and provides habitat for migratory birds. Maintaining secondary treatment standards helps protect this downstream ecosystem from nutrient pollution and oxygen depletion.
