Well permits
Nassau County's health department holds a well permitting delegation agreement with the St. Johns River district. Permits are issued in the county rather than at the District.
Construction, modification and abandonment all require a permit under Chapter 62-532, Florida Administrative Code.
Septic permits
Septic permitting goes through the county environmental health office, and on the newer subdivisions the design flow is set from the bedroom count, which is why an addition can push an existing system out of compliance.
New systems, replacements, repairs to the drain field and tank abandonment are permitted under Chapter 64E-6, Florida Administrative Code.
What that means on the ground
Nassau divides cleanly in two. West of Interstate 95, Callahan, Hilliard and Bryceville are private-well country on large lots, and the septic systems are conventional fields on sandy ground. East of it, Fernandina Beach and Amelia Island are on utility water, where the well work is irrigation and the enemy is salt air on the equipment.
Yulee sits on the line, growing fast enough that the permit the house was built under is often out of date by the time it sells: a bedroom added over a garage changes the design flow the septic system was permitted for, and the county checks.
Both permits are issued by the county health department. Call Flamingo files there for new wells, abandonments, replacement tanks and drain fields alike.
The one number both permits share
A private drinking well has to sit at least 75 feet from any part of a septic system, and an irrigation well 50 feet, under the state onsite sewage rule. Whichever office issues which permit in Nassau County, that measurement is what decides where a new well or a new drain field can go. How the setback plays out on a lot.
