All of the water that is used by the Collier County Public Water Supply System to produce drinking water comes from wells. Water produced from wells is called groundwater.

The groundwater comes from porous, water-bearing underground geologic layers of sand, gravel, or rock that have the capability to produce water. These water-producing layers are called aquifers. In Collier County, generally, as you go deeper into the ground, the water in the aquifers becomes saltier.

The Collier County Water Department operates two hybrid water treatment plants that have the ability to process both fresh groundwater and brackish groundwater from several different aquifers.
