Converse Lagoon Wastewater Treatment Plant - Converse, Louisiana

Converse Lagoon is a wastewater treatment facility located in Converse, Sabine Parish, Louisiana, United States. The plant serves a small population of 436 residents, providing advanced treatment to protect local water quality. As an advanced treatment facility, Converse Lagoon meets high effluent standards typical of US EPA NPDES permits. The plant has a design capacity of 302.83 cubic meters per day and currently discharges 151.42 cubic meters per day, indicating operational headroom. Advanced treatment often includes nutrient removal or disinfection beyond secondary standards. The plant's treated effluent is discharged into local waterways that drain into the Sabine River basin, ultimately flowing to the Gulf of Mexico. This inland location, over 10 km from the coast, reduces direct marine impact but still plays a role in protecting downstream aquatic ecosystems and regional water quality.

Converse Lagoon discharges into the Sabine River watershed, which flows southward through Louisiana and Texas into Sabine Lake and then the Gulf of Mexico. The Sabine River supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's advanced treatment helps reduce nutrient loading and protect downstream water quality in this ecologically sensitive basin.
