The facility has a designed capacity of 321.76 million gallons per year, with an actual discharge volume of 41.64 million gallons per year, indicating ample reserve capacity. The treated effluent is discharged into local streams that drain into the Tallapoosa River watershed, ultimately reaching the Alabama River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality, particularly in the ecologically diverse Mobile Bay basin, which supports a wide range of aquatic life and is an important migratory corridor for fish and birds.

The plant discharges into small streams within the Tallapoosa River basin, which flows into the Alabama River and eventually the Mobile Bay estuary. This watershed supports diverse aquatic ecosystems, including freshwater mussels and fish species. The Mobile Bay area is ecologically sensitive due to its role as a nursery for marine life and a stopover for migratory birds. Proper wastewater treatment is critical to prevent nutrient pollution and maintain water quality in this interconnected system.
