Water Supply Sources

Tampa Bay Water meets the region's drinking water needs with a diverse, flexible supply network, state-of-the-art water quality monitoring, and careful protection of our natural environment.

The region's water is blended from three different sources: groundwatersurface water and desalinated seawater. Tampa Bay Water is the only water utility in the United States to take advantage of these three sources of water combined.

Tampa Bay Water’s regional network of water supply facilities includes a 120 million gallons per day (mgd) surface water treatment plant, a 25 mgd Tampa Bay Seawater Desalination Plant, a 15.5-billion gallon reservoir and 120 mgd permitted capacity of groundwater from wells.
