Water Treatment in Osceola County, FL

About the water in Osceola County

Almost every utility in Osceola County draws from the Upper Floridan Aquifer, a limestone groundwater system that runs under most of Central Florida. Toho Water Authority, which serves St. Cloud, Kissimmee, Poinciana and unincorporated parts of the county, pulls and treats aquifer water locally before distributing it to homes. Kissimmee Utility Authority is the electric utility, not the water utility. (USGS Floridan Aquifer System)

Toho Water Authority's 2025 water quality reports do not list a hardness figure, so the number for your home has to be measured at the tap. Disinfection by-products are the local signal that stands out in the reports. Every install starts with a free in-home test before sizing. (USGS hardness map)
