Project Description

The Dauphin Island Water & Sewer Authority owns and operates a 0.98 MGD wastewater treatment facility. With funding of $11,845,000, a new Biological Nutrient Removal (BNR) water reclamation facility will be designed and constructed, replacing the aging facility. Incorporating the latest technologies, the facility will improve water quality, conserving the health, diversity and resilience of coastal, estuarine and marine habitats. Focusing on long term sustainability, enhanced BNR & solids removal, improved disinfection techniques, removing suspended particulate through filtration and innovation in capacity improvements, this facility will be serve the island’s needs for wastewater treatment. The facility will reduce existing pollutant loads and prevent an increase in future pollutant loads to Aloe Bay and Mississippi Sound. A strong project management and oversight plan will mitigate construction risks associated with construction in a coastal environment and transitioning treatment services over to the new facility. Monitoring is a requirement of the National Pollutant Discharge Elimination System Permit. Effluent values of the new facility during the first year of operation will be compared to those of the aging facility during its last year of operation to determine level of successful avoidance of pollutant discharge. The project will be implemented at 701 LeMoyne Drive, Dauphin Island, Alabama. This activity is located in the Gulf Coast region and will be carried out in the Aloe Bay/Mississippi Sound area along Dauphin Island in Mobile County, Alabama.
