Harry Still Sr WWTP - Bay Minette, Alabama Wastewater Treatment Plant

Harry Still Sr WWTP is a municipal wastewater treatment facility located in Bay Minette, Baldwin County, Alabama. It serves a population of approximately 9,600 people, making it a medium-sized plant for the region. The plant is situated inland, about 50 km from the Gulf Coast, and discharges into local waterways that ultimately drain into Mobile Bay. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Alabama Department of Environmental Management. For a plant serving around 9,600 people, secondary treatment is typically required, with possible additional nutrient removal if discharging into sensitive waters. The designed capacity is 1.00 million gallons per day, indicating adequate capacity for current demand. The plant's treated effluent flows into the Tensaw River system, part of the Mobile-Tensaw River Delta, one of the largest river deltas in the United States. This delta supports diverse aquatic life, including fish, shellfish, and migratory birds. The downstream environment is ecologically sensitive, with extensive wetlands that provide natural water filtration and habitat. Proper treatment at this plant helps protect water quality in Mobile Bay and the Gulf of Mexico.

The plant discharges into the Tensaw River watershed, which flows into the Mobile-Tensaw River Delta and ultimately Mobile Bay. This delta is a biologically rich estuary supporting diverse fish, shellfish, and bird populations. The region's wetlands provide critical flood control and water purification services. Maintaining high treatment standards is essential to prevent nutrient loading and protect downstream habitats.
