Lyndon WWTP - Advanced Wastewater Treatment in Lyndon, Kansas

Lyndon WWTP is an advanced wastewater treatment facility located in Lyndon, Osage County, Kansas. It serves a small population of approximately 1,001 residents, reflecting the scale of a rural community treatment plant. The plant is situated inland, far from coastal influences, and its operations are integral to local water quality management. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the US Clean Water Act for municipal facilities. With a designed capacity of 567.81 million gallons per year and an actual discharge volume of 386.11 million gallons per year, the plant operates well within its capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect receiving waters. The treated wastewater from Lyndon WWTP ultimately drains into the local watershed, contributing to the Marais des Cygnes River basin, which flows into the Osage River and then the Missouri River, eventually reaching the Mississippi River and the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of this major river system.

Lyndon WWTP discharges into the Marais des Cygnes River basin, part of the larger Missouri-Mississippi River system that drains into the Gulf of Mexico. The receiving waters support diverse aquatic life and are important for regional biodiversity. Advanced treatment reduces nutrient loads, helping to mitigate downstream eutrophication and hypoxia in the Gulf of Mexico.
