What moves the price

Field size. Larger homes need larger fields.
Soil and limestone. Shallow limestone in parts of Ocala can require fill or an engineered design.
Springs protection areas. Near Silver Springs and Rainbow Springs, a replacement may need a nutrient reducing system.
Access and restoration. Removing the old field, moving equipment in, and fixing the yard afterward.
Permit scope through FDEP.

How to know it is the drainfield

If backups return within days of a pump-out, or the ground over the field stays soggy, the drainfield is usually the problem. See signs your septic tank is full or failing.

Comparing bids

Get the estimate in writing.
Ask whether the permit, soil test, old field removal, and yard restoration are included.
A bid far below these ranges usually leaves something out.
