Cape Coral is a mid-sized city and the 9th-largest in Florida, home to roughly 175,229 residents. Cape Coral's drinking water comes largely from the same regional sources that serve Florida: Floridan aquifer, Biscayne aquifer, and surface water.
As elsewhere in Florida, the central challenge is saltwater intrusion. Florida reuses roughly half its treated wastewater — one of the highest rates nationally — while fighting saltwater intrusion into the aquifers that supply South Florida.
Florida reuses an estimated 49% of its treated wastewater and maintains established reuse programs; Cape Coral tracks severe to extreme drought conditions on the U.S. Drought Monitor scale.

Related water issues
Saltwater Intrusion
As coastal aquifers are over-pumped and seas rise, saltwater pushes inland and contaminates freshwater supplies for cities from Florida to California.
ExplorePotable Reuse
Advanced purification turns treated wastewater into water that meets or exceeds drinking-water standards — increasingly essential in water-stressed regions.
ExploreAging Infrastructure
Much of America's water infrastructure is decades past its design life, leaking trillions of gallons a year and demanding hundreds of billions in reinvestment.
ExploreAgricultural Demand
Agriculture accounts for the majority of consumptive water use in the West, making farm efficiency and water markets central to any supply solution.
