Valrico Water Hardness & Quality Report (2026)

Valrico, Florida, an unincorporated community in eastern Hillsborough County — a major east Hillsborough County suburban community (Valrico is one of the larger unincorporated communities in eastern Hillsborough County — a primarily residential suburban community in the Brandon–Valrico corridor east of Tampa), a diverse Hillsborough County community with a significant military family, retiree, and working-class professional population, adjacent to Brandon in the rapidly growing east Hillsborough County I-75 corridor, and part of the broader Tampa–Brandon suburban growth zone — draws its municipal water supply from the Upper Floridan Aquifer via the Hillsborough County Public Utilities. Water hardness in Valrico measures 272.5 mg/L — classified as very hard.

Valrico's very hard supply reflects the east Hillsborough County Floridan Aquifer's highly calcareous limestone geology. The Upper Floridan Aquifer at Valrico–east Hillsborough County is hosted in: the Eocene Suwannee Limestone (highly calcareous limestone — the primary east Hillsborough Floridan host); the Eocene Avon Park Formation (highly calcareous dolomite and limestone); and the Oligocene Tampa Formation (calcareous-moderate limestone). HCPU applies limited lime softening in the Valrico east distribution zone, producing the very hard 272.5 mg/L.

At 272.5 mg/L, Valrico residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. HCPU consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
