BLANCHARD SEWERAGE SYSTEM - Caddo Parish, Louisiana Wastewater Treatment

The BLANCHARD SEWERAGE SYSTEM is a municipal wastewater treatment facility located in Caddo Parish, Louisiana, United States. It serves a population of approximately 2,899 residents, classifying it as a small-scale treatment plant under US EPA guidelines. The plant is situated inland, away from coastal zones, and operates under the regulatory framework of the Clean Water Act, which requires NPDES permits for all discharges. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. It has a designed capacity of 719.23 million gallons per year and currently treats 548.89 million gallons annually, indicating operational capacity below design levels. As a US facility, it is subject to EPA and state-level oversight to ensure compliance with water quality standards. The treated effluent is discharged into local water bodies that ultimately drain into the Red River basin, a major tributary of the Mississippi River. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways, which are important for biodiversity and recreation.

The plant discharges into the Red River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic life and is a critical migratory corridor for fish and birds. Advanced treatment reduces nutrient loading, helping to mitigate hypoxia in the Gulf.
