Pine Hill WWTP - Secondary Wastewater Treatment in Pine Hill, Alabama

Pine Hill WWTP is a municipal wastewater treatment plant located in Pine Hill, Wilcox County, Alabama, United States. The facility serves a small population of approximately 680 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids from wastewater before discharge. The plant operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. For small communities like Pine Hill, secondary treatment is the standard requirement to protect water quality. The plant's designed capacity of 473.18 million gallons per year indicates it has room to accommodate future growth, with current discharge volumes at 227.13 million gallons per year. The treated effluent is discharged into a local water body, likely a tributary of the Alabama River system, which flows into Mobile Bay and ultimately the Gulf of Mexico. The plant's inland location, more than 50 km from the coast, reduces direct marine impact. However, its discharge contributes to the overall nutrient load in the watershed, which can affect downstream aquatic ecosystems and the Gulf's hypoxic zone.

The plant discharges into a local water body within the Alabama River basin, which drains into Mobile Bay and the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and shellfish, and is an important migratory corridor for birds. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in downstream estuaries, making effective treatment critical for ecosystem health.
