Florida
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 Upper Floridan plant feeds the address. OUC alone has multiple plants and a reverse-osmosis stage at the Southern plant. 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 Upper Floridan Aquifer. OUC pumps from multiple plants across the City of Orlando, and the OUC Southern Water Treatment Plant uses reverse osmosis on a portion of supply, which produces a softer finished water. 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. That is at the top of the moderately hard band. Outside OUC, the smaller municipal utilities run closer to the raw Floridan Aquifer profile, which USGS classifies as very hard. The exact finished number depends on which plant serves your service address. (USGS hardness map)
