Drinking Water

Current Water Sources

Pinellas County Utilities’ customers receive potable (drinking) water from sources managed by the regional water supplier, Tampa Bay Water. Tampa Bay Water’s system is a reliable and sustainable water system. It’s unlike any other water supply system in the nation because it blends river water, desalinated seawater and groundwater.

Chloramines In Drinking Water

Pinellas County Utilities changed the disinfection process for potable (drinking) water from chlorine to chloramines in 2002. Chloramine is a form of disinfectant that combines chlorine with ammonia. Chloramine and chlorine are disinfectants that destroy potentially harmful bacteria in the potable water system. You can find answers to our frequently asked Chloramine questions here.

Fluoride In Drinking Water

Pinellas County’s first priority is protecting public health. We are in full compliance with the U.S. Environmental Protection Agency’s (EPA) standard for fluoride in drinking water. Pinellas County’s fluoride level is well below EPA’s Maximum Contaminant Level (MCL) of 4.0 parts per million (ppm) and EPA’s Secondary MCL of 2 ppm. This protects you from the cosmetic dental effects that may occur from excess fluoride consumption. Learn about the fluoridation process here.
