Oceanway septic service where new construction meets old drain fields
North of the airport, Oceanway is a subdivision on sewer beside a farm on a tank beside a 1990s house whose drain field has just been driven over by a concrete truck.

Wells in Oceanway: new subdivisions on JEA next to old farms on Floridan wells
Oceanway's older lots are supply wells, deep ones, on ground that was farmed before it was platted. The new subdivisions beside them are on utility water, and the well work there is irrigation. The two kinds of well sit a fence apart and are permitted, sized and treated differently.
On the older wells the question at a sale is nitrate, because agricultural ground carries it, and the standard lab panel answers it. On the new lots the question is iron, because a shallow irrigation bore in this ground stains a new driveway within a season.

What septic systems in Oceanway are actually up against
Oceanway is where Jacksonville is being built right now, and construction is hard on a septic system that is already there. Heavy vehicles crossing a drain field compact the soil the trenches depend on; a builder's silt fence and stockpile in the wrong place changes how water moves across a lot; a new driveway can cover an inspection port nobody marked. The system that worked for twenty years fails the summer after the house next door goes up.
The other pattern is the split lot: an older house that was on a well and a tank sits next to a new one on JEA water and sewer. When the older one sells, the buyer's lender wants to know why it is not connected, and the answer is usually cost and distance rather than any problem with the system.
Call Flamingo marks tank lids and field edges before construction starts on neighbouring ground, and inspects afterwards, because the damage is done in a week and shows up in a year.

Permits and paperwork in Duval County
New and replacement septic systems inside Duval County are permitted through the county environmental health office under the state onsite sewage rule, and JEA sewer availability is checked first, since a lot on an active sewer line may not be permitted for a new drain field at all. Well permits come from a different building: the City of Jacksonville's Environmental Quality Division. Who issues what in Duval County.
Straight answers
Oceanway well and septic questions
Should an Oceanway well be tested for nitrate?
On former farmland, yes. It is part of the standard panel and it is what a lender asks about first on a rural lot.
A builder drove over the drain field. What now?
Inspect it before the symptoms arrive. Compaction shows as slow acceptance at the trenches, and a field caught early can sometimes be restored rather than rebuilt.
The house next door is on sewer. Does that change anything?
Only if the line is close enough that the county treats it as available. That gets checked before a replacement is permitted, not after.
