S.K. Keller Water Treatment Facility

The S.K. Keller Water Treatment Facility treats and distributes 50 to 60 million gallons per day (MGD) of drinking water for more than 700,000 Pinellas County residents, visitors and businesses. This plant was replaced in the early 2010s with a new state-of-the-art drinking water treatment facility. The current facility includes 40 million gallons of water storage with pumps that can move over 100 million gallons of water a day.

The service area begins east of Tarpon Springs and ends at Fort De Soto Park. We also supply water to the cities of Clearwater, Pinellas Park and Safety Harbor.

The water treatment processes include:

• Aeration.
• Primary Disinfection with Free Chlorine Residual.
• Secondary Disinfection with Chloramination – Adding Ammonia and Chlorine.
• pH Stabilization with Sodium Hydroxide.
• Polyphosphate Inhibitor for Corrosion Control of Pipes.
• Fluoride for Dental Health.

Previous Water Sources

Before 1998, Pinellas County used safe and reliable drinking water deep underground. Pinellas County’s groundwater comes from the Floridan Aquifer, a thick porous limestone under the Earth’s surface. The aquifer spreads throughout Florida as well as parts of Alabama, Georgia and South Carolina. This water-rich source is one of the largest freshwater aquifers in the nation and provides the safest, highest quality water available.
