South Florida is one of the wettest areas of the country that typically gets about 53 inches of rainfall a year. Approximately 90 percent of the water used in homes and businesses comes from groundwater sources called aquifers. The remaining 10 percent comes from surface waters such as lakes, community ponds, and rivers. Both surface and groundwater supplies are primarily recharged by rainfall.
