⚠️ HB 1379: ENR Systems Required in Santa Fe / Silver Springs Basin on Lots ≤1 Acre
If your Alachua County property is within the Santa Fe River basin or Silver Springs basin and your lot is one acre or smaller, a conventional septic replacement is not permitted. Florida HB 1379 (July 2023) requires an ENR system. Properties near High Springs, LaCrosse, and the Santa Fe River corridor are most likely to be in an affected basin. Verify your basin status with your contractor before accepting any quote.
📋 Permit Authority: Alachua County Health Department (Not FL DEP)
As of 2026, Alachua County septic permits are still processed through the Alachua County Health Department Environmental Health division at 352-334-7930 — not FL DEP (as in Marion County). Your licensed contractor files the permit application. Budget up to 30 days for approval after submitting a complete application with site evaluation results.
💡 ENR Rebate: 50% Back, Up to $5,000
If your property requires an ENR upgrade, Alachua County's EPD offers rebates of 50% of the upgrade cost, up to $5,000, for qualifying properties in the Santa Fe River or Silver Springs basin. Apply before work begins — contact 352-264-6829 or Sgreco@alachuacounty.us. The rebate significantly offsets the cost difference between a conventional and ENR system.
About Septic Tank Replacement in Alachua County
Most septic tank replacements in Alachua County involve replacing not just the tank but the drain field as well — systems that have deteriorated to the point of needing a new tank have almost always stressed the drain field in the process. The work requires a permit from the Alachua County Health Department (352-334-7930), not the Florida Department of Environmental Protection. Unlike Marion County, which transferred septic permitting to FL DEP in July 2025, Alachua County still processes all OSTDS permits through the county health department. Your licensed contractor handles the application — budget up to 30 days for permit approval after submission.
Soil conditions divide Alachua County's replacement landscape into two main categories. Properties on Arredondo series soil — the deep, well-drained sandy upland soil that underlies most of Gainesville's suburban neighborhoods from Haile Plantation to Jonesville, Newberry, and Archer — almost always qualify for standard conventional gravity drain fields. Arredondo soil has a seasonal high water table more than 60 inches below grade, giving drain fields ample room to function and making replacement relatively straightforward. Properties on Jonesville series soil — more common in the eastern and southeastern county, toward Hawthorne and Micanopy — have limestone closer to the surface. Jonesville soil profiles are shallower and require careful evaluation before system design. Some Jonesville-soil lots have insufficient depth for a conventional drain field and require a mound system or a low-pressure dosing system.
The basin location question matters most for properties in High Springs, LaCrosse, Newberry's western edges, and the Santa Fe River corridor. If your lot is within the Santa Fe River basin or Silver Springs basin and is one acre or smaller, Florida's HB 1379 (effective July 1, 2023) requires an Enhanced Nutrient-Reducing OSTDS for any new installation or replacement — a conventional system is no longer permitted. The approved ENR technologies are Aerobic Treatment Units (ATUs), In-Ground Nitrogen-Reducing Biofilters (INRBs), and Performance-Based Treatment Systems (PBTS). ATUs cost $8,000–$20,000 and require biannual professional servicing. INRBs are passive — no mechanical components, no service contract — and typically run $4,000–$8,000 installed. Alachua County's Environmental Protection Department offers rebates covering 50% of the upgrade cost, up to $5,000, for qualifying properties. Contact 352-264-6829 or Sgreco@alachuacounty.us to verify eligibility before any work begins.
Frequently Asked Questions — Septic Tank Replacement in Alachua County
How much does septic tank replacement cost in Alachua County, FL? ▾
A standard conventional septic system replacement on Alachua County's typical upland Arredondo soil costs $5,000–$14,000 installed. Mound systems for properties with Jonesville soils or high seasonal water tables run $9,000–$22,000. ENR systems required in the Santa Fe River or Silver Springs basin (lots ≤1 acre) cost $8,000–$25,000, but the Alachua County rebate program offers up to $5,000 back on qualifying upgrades. A site evaluation must be completed before any estimate can be finalized.
Who issues septic permits in Alachua County? ▾
The Alachua County Health Department handles all OSTDS (septic system) permits as of 2026 — Alachua County has not transferred permitting to FL DEP, unlike Marion County. Contact the Environmental Health division at 352-334-7930. Your licensed septic contractor will file the permit application as part of the replacement project.
Do I need an ENR system to replace my septic in Alachua County? ▾
Only if your property is within the Santa Fe River basin or Silver Springs basin and your lot is one acre or smaller. Florida HB 1379 (July 2023) requires an ENR system (ATU, INRB, or PBTS) for new installations and replacements in those areas on small lots. Properties elsewhere in Alachua County — most of Gainesville, Newberry, Archer, Waldo, and Hawthorne — can still use conventional systems. Your contractor should verify basin boundaries before designing a replacement system.
How long does septic tank replacement take in Alachua County? ▾
From initial assessment to completed installation, plan on 5–9 weeks. The site evaluation must be completed before the permit application. Permit approval at the Alachua County Health Department takes up to 30 days. Actual installation takes 1–4 days depending on system type. ENR systems (ATUs or INRBs) may take slightly longer to source and install than conventional systems. Starting the process early avoids delays if your system is failing.
