The S.K. Keller Water Treatment Facility is responsible for the treatment and distribution of approximately 50-60 million gallons per day (MGD) of drinking water for more than 700,000 residents, visitors, and businesses of Pinellas County. The water service area begins east of Tarpon Springs and terminates at Fort De Soto Park. The facility includes 40 million gallons of water storage with pumps capable of moving over 100 million gallons of water a day. Wholesale water service is supplied to the cities of Clearwater, Pinellas Park, and Safety Harbor.
In the early 2010s, the aging water plant was replaced with a new state-of-the-art drinking water treatment facility.
The water treatment processes include:
- Primary disinfection using free chlorine residual
- Secondary disinfection using chloramination
(addition of ammonia and chlorine)
- pH stabilization using sodium hydroxide
- Addition of polyphosphate inhibitor for corrosion control of pipes
- Addition of fluoride for dental health
Previous Water Sources:
Prior to 1998, Pinellas County’s drinking water production started with safe and reliable water located deep beneath the ground. In Pinellas County, groundwater comes from the Floridan Aquifer, a thick sequence of porous limestone beneath the Earth’s surface, which spreads throughout Florida as well as parts of Alabama, Georgia, and South Carolina. This water-rich source is considered to be one of the largest freshwater aquifers in the nation and can provide the safest and highest quality water available.
