The client’s needs
The region was dependent on groundwater supplies, but with a fast growing population, this solution wasn’t sustainable and resulted in damage to natural ecosystems.
Tampa Bay Water was seeking a new water supply source and a solution to deal with the variable conditions in flows and in raw water quality due to the adjacent wetlands and other natural systems.
Veolia Water Technologies was chosen to Design and Build the new Tampa Bay drinking water treatment plant.
To relieve the pressure on the groundwater resource, the new plant blends water from the Alafia River, the Tampa Bypass Canal, the Hillsborough River and the C.W. Bill Young Regional Reservoir.
The Actiflo® high rate clarification technology was selected for its unique ability to treat raw water with high variability in water treatment.
The multi-barriers treatment process also includes : ozonation, filtration through granular activated carbon gravity filters, disinfection, chemical dosing and clay and sludge processing.
A hydrobiological monitoring program, which monitors hydrological and biological conditions in the sources, has been implemented and is essential to determine when water production should be adjusted.
The drinking water production capacity went from 307,360 to 524,000 m3/day, and with the use of the surface water sources, the groundwater resource is preserved. This new facility supplies drinking water that exceeds federal and state drinking water quality standards.
The project has won multiple awards including the 2012 Plant Operation Excellence award from the Florida Department of Environmental Protection.
