Lincoln WWTP is a municipal wastewater treatment facility located in Lincoln, Arkansas, serving a population of approximately 2,249 residents. The plant is situated in Washington County, within the Ozark Highlands region, and plays a key role in managing local wastewater for this small community. As a US-based plant serving fewer than 10,000 people, Lincoln WWTP falls under the regulatory framework of the Clean Water Act, administered by the Arkansas Department of Energy and Environment. Facilities of this scale typically require secondary treatment as a minimum standard, with permits issued under the National Pollutant Discharge Elimination System (NPDES) to ensure compliance with water quality standards.

This downstream connection highlights the plant's role in protecting regional water quality and aquatic habitats in the Mississippi River Basin.
Environmental context
The plant discharges into the Illinois River watershed, a tributary of the Arkansas River, which flows into the Mississippi River and ultimately the Gulf of Mexico. This water body supports diverse aquatic life and is an important migratory corridor for fish and birds. The Ozark Highlands region features karst topography, which can increase groundwater vulnerability, making proper wastewater treatment critical for protecting local springs and streams.
