ARCHIE WWTP is a municipal wastewater treatment facility located in Archie, Cass County, Missouri, United States. The plant serves a population of approximately 1,170 residents, providing essential sanitation services for this small community. As a secondary treatment plant, it meets the standard requirements for organic matter and suspended solids removal under the US Clean Water Act. The plant has a designed capacity of 492.10 cubic meters per day and currently handles a discharge volume of 378.54 cubic meters per day, indicating operational headroom. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The facility operates under the US EPA's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits and monitoring requirements to protect water quality. The treated effluent from ARCHIE WWTP is discharged into local streams that are part of the Missouri River watershed. The Missouri River eventually flows into the Mississippi River, which drains into the Gulf of Mexico. This downstream connection highlights the plant's role in protecting both local aquatic ecosystems and the broader Gulf of Mexico watershed from nutrient pollution and other contaminants.

The plant discharges into tributaries of the Missouri River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The local watershed supports diverse aquatic life and is part of a larger system that experiences seasonal flooding and agricultural runoff. The plant's secondary treatment helps reduce organic loading and suspended solids, mitigating impacts on downstream water quality and aquatic habitats.
