Water Treatment in Orange County, FL

Orange County is the densest part of the Pure Agua footprint. Six utilities serve the Orange County cities we cover, and each one runs a different finished-water profile depending on which plant feeds the address. OUC alone runs seven water plants. That is why a sized-from-spec system in Orlando is rarely the right system in Apopka or Winter Garden without a fresh on-site test.

About the water in Orange County

Orange County water utilities draw almost exclusively from the Floridan Aquifer; OUC and the City of Apopka both name the Lower Floridan as their source. OUC runs seven water plants and treats with ozone and then chlorine. Outside Orlando city limits, Orange County Utilities and the municipal utilities of Apopka, Winter Garden, Ocoee, and Winter Park each run their own treatment. (USGS Floridan Aquifer System)

OUC publishes finished-water hardness of 129 ppm as calcium carbonate, which the utility itself reports as roughly 7 grains per gallon. On the USGS scale that is in the hard band (121 to 180 mg/L). Orange County Utilities does not list a hardness figure in its 2025 report, and the City of Apopka reports a range of 120 to 200 mg/L (7.0 to 11.7 grains per gallon). The exact finished number depends on which plant serves your service address. (USGS hardness map)
