HOLLIDAY WWTF - Monroe County, Missouri Wastewater Treatment Plant

HOLLIDAY WWTF is a municipal wastewater treatment facility located in Monroe County, Missouri, United States. The plant serves a small population of 137 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 75.71 units, and it currently discharges 53.00 units of treated wastewater, indicating operational headroom. As a small facility, it is subject to state-level oversight by the Missouri Department of Natural Resources, which issues permits and ensures compliance with water quality standards. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River Basin, a major hydrological system that flows into the Gulf of Mexico. The plant's operations contribute to protecting downstream aquatic ecosystems by reducing pollutant loads before discharge.

The plant discharges into a tributary of the Mississippi River Basin, which flows southward to the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's secondary treatment helps mitigate nutrient and organic pollution, reducing the risk of eutrophication in downstream waters.
