Birdsong WWTP - Advanced Wastewater Treatment in Birdsong, Arkansas

Birdsong WWTP is a municipal wastewater treatment plant located in Birdsong, Mississippi County, Arkansas. It serves a small population of 40 residents, reflecting the rural character of the area. The plant is situated in the Mississippi River Delta region, a flat, agricultural landscape. The facility provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. Advanced treatment typically involves biological nutrient removal or tertiary filtration. The plant has a designed capacity of 113.56 million gallons per day, with an actual discharge volume of 3.79 million gallons per day, indicating significant reserve capacity. Under the U.S. Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Arkansas Department of Energy and Environment. The treated effluent is discharged into a receiving water body that ultimately drains into the Mississippi River, one of the largest river systems in North America. The Mississippi River flows into the Gulf of Mexico, where nutrient pollution contributes to a seasonal hypoxic zone. Advanced treatment at Birdsong WWTP helps reduce nutrient loading, supporting downstream water quality and aquatic life.

Birdsong WWTP discharges into a local waterway that is part of the Mississippi River basin. The Mississippi River flows southward through Arkansas and into the Gulf of Mexico. This region is ecologically significant as it supports diverse aquatic habitats and is a major migratory corridor for birds and fish. Nutrient runoff from agricultural areas in the Mississippi Delta can exacerbate algal blooms and hypoxia in the Gulf, making advanced nutrient removal at treatment plants like Birdsong WWTP important for downstream ecosystem health.
