Shreveport Lucas WWTP - Large Municipal Wastewater Treatment Plant in Shreveport, Louisiana

Shreveport Lucas WWTP is a municipal wastewater treatment facility located in Shreveport, Caddo Parish, Louisiana. Serving an estimated population of 187,000, it is a large-scale plant that plays a critical role in managing wastewater for the city and surrounding areas. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality. For a plant of this size, secondary treatment is typically required, with potential additional nutrient removal to protect downstream water quality. The plant's treated effluent is discharged into the Red River, which flows south to join the Mississippi River and ultimately the Gulf of Mexico. This connection makes the plant's performance important for the health of the Mississippi River Basin and the Gulf's hypoxic zone.

The plant discharges into the Red River, a major tributary of the Mississippi River that drains into the Gulf of Mexico. The Red River basin supports diverse aquatic life and is an important migratory corridor for fish and birds. Downstream, the Mississippi River carries nutrients that contribute to seasonal hypoxia in the Gulf, making nutrient management at plants like Shreveport Lucas WWTP ecologically significant.
