ARITON LAGOON Wastewater Treatment Plant, Dale County, Alabama

ARITON LAGOON is a municipal wastewater treatment plant located in Dale County, Alabama, United States. The facility serves a small population of approximately 350 residents, reflecting its role as a local infrastructure asset for a rural community. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 378.54 megaliters and an annual discharge volume of 113.56 megaliters, the plant operates well below its capacity, indicating ample headroom for current demand. The treated effluent is discharged into local waterways that ultimately drain into the Choctawhatchee River basin and then to the Gulf of Mexico. This connection to a major coastal ecosystem underscores the importance of maintaining effective treatment to protect downstream water quality and aquatic habitats.

The plant's discharge enters the Choctawhatchee River watershed, which flows south through Alabama and Florida before emptying into the Gulf of Mexico. This region supports diverse aquatic life, including fish and migratory birds, and the river's health is critical for both local ecology and downstream coastal waters. Effective secondary treatment helps reduce nutrient loads and protect the sensitive estuarine environment.
