Jennette WWTP - Secondary Wastewater Treatment in Crittenden County, Arkansas

Jennette WWTP is a municipal wastewater treatment facility located in Crittenden County, Arkansas, United States. The plant serves a small population of 115 residents and operates as part of the local wastewater infrastructure in the Mississippi River Delta region. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for most municipal facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 378.54 million gallons per day and currently discharges 3.79 million gallons per day, indicating significant reserve capacity. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River, one of the largest river systems in North America. The Mississippi River flows into the Gulf of Mexico, supporting diverse aquatic ecosystems and important fisheries. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program administered by the Arkansas Department of Energy and Environment.

The plant's discharge enters the Mississippi River watershed, which drains a vast area of the central United States before reaching the Gulf of Mexico. The Mississippi River and its floodplain support critical habitats for migratory birds, fish, and other wildlife. Nutrient loading from wastewater and agricultural runoff in this region contributes to the seasonal hypoxic zone in the Gulf of Mexico, making effective treatment important for downstream water quality.
