LAKIN WWTP - Secondary Wastewater Treatment in Kearny County, Kansas

LAKIN WWTP is a municipal wastewater treatment facility located in Kearny County, Kansas, United States. The plant serves a population of approximately 2,275 residents, reflecting a small community in the rural High Plains region. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 1,188.62 units and an average daily discharge of 859.29 units, the facility operates below its capacity, indicating room for future growth. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local watercourse that ultimately drains into the Arkansas River basin, a major tributary of the Mississippi River system. The plant's location in the semi-arid Kansas plains means that water quality management is critical for sustaining local aquatic habitats and downstream ecosystems.

The plant discharges into a tributary of the Arkansas River, which flows through the Great Plains and eventually joins the Mississippi River. This watershed supports diverse aquatic life and is important for irrigation and municipal water supplies in the region. The semi-arid climate makes the receiving waters sensitive to nutrient loading, which can lead to algal blooms and oxygen depletion.
