Water Rates

The City of St. Petersburg purchases softened water from the regional supplier, Tampa Bay Water, which operates the Tampa Bay Regional Surface Water Treatment plant. This plant currently produces a blend of surface water and groundwater with desalinated water scheduled to be added to the mix in early 2004. This variety of water sources ensures us a drought-resistant drinking water supply which complies with or exceeds all local, state, and federal drinking water standards.

Upon leaving Tampa Bay Waters facility, the water is further treated at the Cosme Water Treatment facility which has been honored several times as the Best Operated Water Treatment Plant in Florida. And as a customer of the City of St. Petersburg's Municipal Water System, you enjoy high-quality water that has been rated the best tasting municipal water in Florida. For questions or concerns about water quality, call 727-893-7261.

If you recently moved to the St. Petersburg area you may not be accustomed to the taste of our water. This is because water sources are different throughout the state and nation. Some communities use groundwater; other communities rely upon river or lake water for their water supplies. You may have lived where you were served by a private well. Often, private wells receive little or no treatment. However, to assure that a water supply is safe from harmful organisms, state and federal agencies require that all municipal water supplies provide disinfection treatment.

In May 2002, the City of St. Petersburg, like many communities throughout the United States, began chloramination of its water supply in order to disinfect and eliminate any harmful organisms that may be present in the water. In addition, the City of St. Petersburg began fluoridation of its water supply in 1993. Fluoride has been shown to help prevent tooth decay, especially in children. It is important to inform your dentist that fluoride is added to your water so that any fluoride treatments can be adjusted appropriately.

You may be contacted by individuals representing private water firms requesting permission to test your water. They may attempt to sell you a home water treatment system. These companies are not affiliated with nor endorsed by the City of St. Petersburg. Although you may wish to install one of these home treatment systems, please be aware that your water supply meets all public health standards without additional treatment.

The City of St. Petersburg's Water Resources department is committed to providing quality water for your needs and enjoyment. If you have any questions about the quality of your water, contact our 24-hour Dispatch office at 727-893-7261.
