When replacement is needed
When a drain field can no longer absorb water, replacement is the only lasting fix. Common signs are sewage surfacing in the yard, repeated backups even after pumping, and a field that stays wet in dry weather.
How replacement works in Marion County
- A septic company confirms the field has failed, not just the tank, filter or lines.
- A site evaluation checks your soil and the seasonal high water table. That sets the size and type of the new field.
- The permit is filed with the Florida DEP, which has handled septic permitting in Marion County since July 1, 2025.
- The old field is abandoned or removed and the new one is installed, usually in a few days of work.
- DEP inspects the installation before it is covered.
What it costs
Florida drain field replacements commonly run $5,000 to $15,000. Tough sites, such as a high water table that requires a raised (mound) system, can reach $20,000 or more. Tank replacement is usually priced separately.
Near the springs, check the nitrogen rules first
Parts of Marion County fall inside the Silver Springs and Rainbow Springs protection areas. A repair or replacement there may require an enhanced nitrogen-reducing system, which adds significant cost. Read our springs and permits guide before you get quotes.

How long does a new drain field last?
Often 20 years or more with regular pumping. Skipping pump-outs is the most common reason fields fail early.
Can I replace just part of the field?
Sometimes. If only one section has failed, a contractor may be able to add or replace trenches instead of the whole field.
