Raw water comes from 48 wells in the Cocoa well field:
34 wells drilled 400 to 600 feet into the Floridan Aquifer
14 wells drilled into the overlaying intermediate aquifer
Because of concerns about saltwater intrusion, the St. Johns River Water Management District limited any further expansion of the well field.
The well field can produce a maximum of 60 million gallons a day (mgd) with all wells pumping simultaneously.
Safe well field management practices advise an operating rate that allows for well rotation to alleviate stress on the aquifer and provide down time for well repair and maintenance. Such management practices allow Cocoa to operate the well field safely at 27.38 mgd for average flows and 45 mgd for maximum flows during 2012.
