Lake City WWTP - Advanced Wastewater Treatment in Lake City, Arkansas

Lake City WWTP is a municipal wastewater treatment facility located in Lake City, Craighead County, Arkansas. The plant serves a population of approximately 2,082 residents, providing essential sanitation services for this small community in the northeastern part of the state. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,188.62 thousand cubic meters per year and an actual discharge volume of 707.87 thousand cubic meters per year, the facility operates well within its capacity. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Arkansas Department of Energy and Environment - Division of Environmental Quality. The treated effluent is discharged into local receiving waters that ultimately drain into the Mississippi River basin. This region is part of the larger Mississippi River watershed, which supports diverse aquatic life and provides critical habitat for migratory birds. The plant's advanced treatment helps protect downstream water quality in this ecologically significant river system.

The plant discharges into local streams that flow into the St. Francis River, a tributary of the Mississippi River. The Mississippi River basin is one of the largest watersheds in North America, supporting a wide range of aquatic species and providing important migratory corridors for birds. The advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing hypoxic zones in the Gulf of Mexico.
