Our septic installation Silver Springs FL crews handle the whole job, from the soil evaluation to the final state inspection, across Ocala and Marion County.

What does each type of septic system cost?

The type of system your lot needs is the biggest factor in the price. Deep sandy soil with a normal water table can use a conventional system. A high water table, shallow limestone, a small lot or a springs protection area can call for a mound, an ATU or a nitrogen-reducing system.

System typeBest forApprox. installed cost
Conventional tank and drain fieldDeep sandy soil, normal water table$7,000–$15,000
Chamber drain fieldSmaller areas, faster install$8,000–$16,000
Mound (elevated) systemHigh water table or shallow limestone$12,000–$25,000
Aerobic treatment unit (ATU)Small lots, poor soil, higher treatment$12,000–$20,000
Nitrogen-reducing systemSprings protection areas, smaller lots$15,000–$30,000

Prices are approximate. Your site evaluation sets the final design and price.

What changes the price of a new septic system?

Six things move the price most: soil and water table, system type, tank size, lot access, rock, and whether an old system has to be removed. A flat, open lot with deep sand is the cheapest. A wooded lot with limestone near the surface and a high water table costs the most.

  • Soil and water table. Florida rules set how far the drain field must sit above the seasonal high water table. A high table can mean fill dirt or a mound.
  • System type. ATUs and nitrogen-reducing systems cost more up front and need ongoing service.
  • Tank size. Larger homes with more bedrooms need a larger tank and field. See what size septic tank you need.
  • Access. Tight lots, fences and trees slow the excavator.
  • Rock. Shallow limestone has to be broken out, which adds equipment time.
  • Old system removal. Replacing a failed system means pumping, crushing or removing the old tank.

What permits do you need in Marion County?

A new or replacement septic system in Florida needs a site evaluation, a system design that fits the soil, a construction permit through the state onsite sewage program, and an inspection before the system is covered. Permit and design costs are part of the ranges above. We file the paperwork and schedule the inspections.

Parts of Marion County sit in the Silver Springs and Rainbow Springs springsheds. In those areas, newer rules can require a nitrogen-reducing system for new homes on smaller lots. We check your parcel during the site visit, so the design matches the rules before you pay for anything.

How long does septic installation take?

Most installs take 2 to 5 days of work once the permit is issued. The permit step often takes longer than the build, so plan ahead. Weather can push dates back in the summer rainy season, because the soil must be dry enough to dig and set the field.

  1. Site visit and soil evaluation. We look at the lot, test the soil and find the water table.
  2. Design and permit. The system is designed and the permit is filed.
  3. Excavation and tank set. The tank goes in and the lines are run.
  4. Drain field build. Trenches, chambers or a mound are built to the design.
  5. Inspection. The state inspects before the system is covered.
  6. Backfill and final grade. The yard is graded so water runs away from the field.

Should you repair or replace your system?

Replace the system when the tank has collapsed or is rusted steel, when the whole drain field has failed, or when the home has more bedrooms than the system was built for. If only one part is failing, a repair costs far less. A tank repair runs about $150 to $1,500, and a partial drain field rebuild about $2,500 to $8,000.

Before you replace anything, ask for an inspection. Buying a home with an older system? Order an ocala septic tank inspection before closing. Our Ocala septic inspection checks the tank, baffles, pipes and field and tells you what is actually broken. Many systems only need septic tank repair Ocala work or drain field repair Ocala to keep running.

How do you protect a new septic system?

  • Keep cars, trucks and pools off the tank and field.
  • Plant only grass over the field.
  • Pump the tank every 3 to 5 years.
  • Install risers so the lids are easy to reach. See septic tank risers.
  • Do not flush wipes, grease or chemicals. See what not to flush.
