KENNER STP 3 - Kenner, Louisiana Wastewater Treatment Plant

KENNER STP 3 is a municipal wastewater treatment facility located in Kenner, Louisiana, along the Mississippi River Trail. It serves a population of approximately 113,712 residents in the Jefferson Parish area, making it a large-scale treatment plant under US regulatory standards. 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 standards to protect downstream water quality. The plant discharges treated effluent into the Mississippi River, which flows into the Gulf of Mexico. This discharge contributes to the nutrient load in the river, which is a key factor in the seasonal hypoxic zone in the Gulf. The plant's performance is critical for maintaining water quality in the lower Mississippi River basin.

The plant discharges into the Mississippi River, which flows through Louisiana and empties into the Gulf of Mexico. This river system supports diverse aquatic life and is a major migratory corridor for fish and birds. The discharge contributes to nutrient loading, which can exacerbate algal blooms and hypoxia in the Gulf. The plant's treatment level is important for mitigating these downstream ecological impacts.
