Linn Creek WWTP - Secondary Treatment Plant in Linn Creek, Missouri

Linn Creek WWTP is a municipal wastewater treatment facility located at 222 East Valley Drive in Linn Creek, Missouri, a small community in Camden County. The plant serves a population of approximately 220 residents and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for municipal wastewater discharges. The plant's designed capacity is 211.98 million gallons per year, and it currently discharges 113.56 million gallons per year, indicating it operates well below its capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, which set effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Osage River, a tributary of the Missouri River. The Missouri River flows into the Mississippi River, which empties into the Gulf of Mexico. The plant's discharge contributes to the overall water quality of these downstream systems, which support diverse aquatic life and are important for regional ecology.

The plant's discharge enters a local stream that flows into the Osage River, part of the Missouri River basin. The Osage River is a major tributary of the Missouri River, which joins the Mississippi River and eventually reaches the Gulf of Mexico. The watershed supports diverse aquatic species and is an important migratory corridor for fish. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream water quality in this inland basin.
