LAWSON WWTP - Advanced Wastewater Treatment in Lawson, Missouri

LAWSON WWTP is an advanced wastewater treatment plant located in Lawson, Ray County, Missouri. The facility serves a population of about 2,473 and has a designed capacity of 1,135.62 thousand cubic meters per year, with an actual discharge volume of 965.28 thousand cubic meters. It is situated inland, more than 50 kilometers from the coast. The plant employs advanced treatment processes, which exceed the secondary treatment standards typically required under the U.S. Clean Water Act. For small communities like Lawson, advanced treatment often targets nutrient removal to protect sensitive downstream waters. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Missouri Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent from LAWSON WWTP is discharged into a local water body that eventually drains into the Missouri River watershed. The Missouri River flows into the Mississippi River, which empties into the Gulf of Mexico. This downstream connection highlights the plant's role in reducing nutrient loads that contribute to the Gulf of Mexico hypoxic zone, making its advanced treatment particularly significant for regional water quality.

LAWSON WWTP discharges into a tributary of the Missouri River, which flows into the Mississippi River and ultimately reaches the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient pollution, supporting the health of downstream aquatic ecosystems. The facility is located in a rural agricultural area, where runoff can contribute to nutrient loading, making the plant's nutrient removal capabilities important for local water quality and the broader Mississippi River basin.
