Septic Tank Installation and Replacement in Ocala
Building on a lot without sewer, or replacing a system that’s failed for good? Installation in Marion County comes with its own permits and, on many lots, its own system requirements. Call (352) 280-3260 to reach a licensed local septic installer who handles both.
Repair or replace?
Not every failing system needs replacing. A cracked baffle, a bad pump or a clogged line can often be fixed. Replacement usually makes sense when:
- The tank itself is cracked, collapsing or rusted through (older steel tanks)
- The drain field has failed and can’t be restored
- The system is too small for the house after an addition
- Repairs keep coming back every year or two
A septic company can inspect the system and tell you which situation you’re in. Septic repair →
Marion County rules you should know
- Permits come from the Florida Department of Environmental Protection. In most Florida counties the county health department handles septic permits. In Marion County, it’s DEP.
- Nitrogen-reducing systems on smaller lots. Much of Marion County sits in the Silver Springs and Rainbow Springs protection areas. Since 2023, new systems on lots of one acre or less without sewer access must be nitrogen-reducing systems rather than a conventional tank and drain field.
- Failing systems may need an upgrade. In priority areas, a system that needs a repair permit may have to connect to sewer if it’s available or upgrade to nitrogen reduction.
A local installer will know which of these apply to your address before you commit to anything.
Types of nitrogen-reducing systems
- In-ground nitrogen-reducing biofilters: a layered drain field that filters nitrogen before it reaches groundwater.
- Aerobic treatment units: a tank that adds oxygen to break waste down more completely.
- Performance-based treatment systems: engineered systems designed for a specific site.
These cost more than a standard tank to install and maintain, so get quotes from a company that installs them regularly.
How installation works
- Site evaluation and soil test to size the system and pick the right type.
- Permit application to DEP with the system design.
- Installation of the tank and drain field or treatment unit.
- Inspection and final approval before the system goes into use.
Timelines depend mostly on permitting. Ask your installer for a realistic schedule up front.
What installation costs
In Central Florida, a conventional system typically runs $3,000–$7,000, and a nitrogen-reducing system $10,000–$35,000, based on published 2026 cost data. Lot size, soil, water table, tank size and permit requirements all move the price. Get at least two written quotes.
Common questions
Do I need a nitrogen-reducing system?
If you’re installing a new system on a lot of one acre or less without sewer, likely yes in much of Marion County. An installer can confirm for your address.
Can I connect to sewer instead?
Only where county or city sewer lines reach your property. Some areas near Ocala and in Silver Springs Shores are being studied for sewer expansion.
How long does a new septic system last?
A well-maintained system often lasts decades. Regular pumping is the biggest factor. Septic pumping →
