Dale Mabry Advanced Wastewater Treatment Plant (AWWTP) - Northdale, Florida

Dale Mabry Advanced Wastewater Treatment Plant (AWWTP) is located in Northdale, Hillsborough County, Florida, within the Tampa Bay metropolitan area. The facility serves a population of approximately 45,361, classifying it as a medium-sized municipal treatment plant in the region. As an advanced wastewater treatment plant, it likely employs tertiary treatment processes to meet stringent nutrient removal standards required for discharge into sensitive water bodies. The plant's designed capacity is 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flows. Under the US Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Florida Department of Environmental Protection. The plant's treated effluent ultimately discharges into the Tampa Bay estuary, a vital ecological and economic resource. Tampa Bay is the largest open-water estuary in Florida, supporting diverse marine life including seagrasses, mangroves, and fisheries. The bay's watershed drains much of west-central Florida, and nutrient management from wastewater plants is critical to prevent algal blooms and maintain water quality.

The plant discharges into the Tampa Bay watershed, which flows into the Gulf of Mexico. Tampa Bay is a shallow, subtropical estuary that supports extensive seagrass beds, mangrove forests, and a rich diversity of fish and bird species. Nutrient loading from wastewater and urban runoff has historically caused algal blooms and hypoxia, making advanced treatment essential for protecting the bay's ecological health and recreational uses.
