Maplesville WWTP - Advanced Wastewater Treatment in Maplesville, Alabama

Maplesville WWTP is a municipal wastewater treatment plant located in Maplesville, Chilton County, Alabama. It serves a small population of 270 residents, reflecting the rural character of the area. The plant is situated on Shady Side Drive and operates under the regulatory framework of the United States Clean Water Act, administered by the Alabama Department of Environmental Management. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the Clean Water Act for municipal facilities. Advanced treatment typically includes nutrient removal or other processes to reduce pollutants further. The plant has a designed capacity of 280.12 million gallons and currently discharges 56.78 million gallons annually, indicating significant spare capacity. The treated effluent is discharged into a local water body that ultimately drains into the Alabama River basin. The Alabama River flows southwest to join the Mobile River and then into Mobile Bay, an ecologically important estuary on the Gulf of Mexico. The plant's advanced treatment helps protect downstream water quality in this sensitive coastal ecosystem.

The plant discharges into a tributary of the Alabama River, which flows into Mobile Bay, a large estuary that supports diverse aquatic life including fish, shellfish, and migratory birds. The bay is a critical habitat for several species and is influenced by nutrient inputs from upstream sources. Advanced treatment at Maplesville WWTP reduces nutrient loading, helping to mitigate eutrophication risks in the downstream estuary.
