General questions go to (407) 665-3604 and inspection requests to (407) 665-3239. Source: DOH-Seminole Onsite Sewage and Disposal

Parts of southwest Seminole County fall inside the Wekiwa and Rock Springs Priority Focus Area, which FDEP identifies as more vulnerable to nitrogen pollution from septic systems under the basin management action plan. Source: FDEP enhanced nutrient-reducing OSTDS permitting
Effective July 1, 2023, HB 1379 requires that in impacted basin management action plan areas, new septic systems serving lots of one acre or less install an enhanced nitrogen-reducing system (ENR-OSTDS) targeting at least 65% nitrogen reduction, rather than a conventional system.

Florida's private-provider inspection rule became stricter and far more concrete on July 9, 2025, when the amended OSTDS rule (Chapter 62-6, F.A.C.) took effect. A private provider inspector must file an authorization with the department before the first inspection, submit inspection results within seven calendar days, enter them in the county's inspection portal, and include photographs of the system; a $35 inspection review fee applies to each report that results in construction approval. The rule also states that a master septic tank contractor may not perform the construction inspection on their own repair - a conflict-of-interest limit worth knowing when one Sanford-area company offers to both fix the system and sign off on the work.

Since July 1, 2022, Florida owners or authorized contractors may hire a licensed private provider to perform OSTDS inspections instead of waiting for the health department, which can speed up Seminole County projects. Source: DOH-Seminole Onsite Sewage and Disposal
Seminole County runs a Septic Upgrade Incentive Program through its Holistic Water Policy to help eligible property owners upgrade or convert aging septic systems that affect local water quality; eligibility and amounts are set by the county. Source: Seminole County Septic Upgrade Incentive Program
Septic tank contracting is a registered trade in Florida. The state publishes a searchable Septic Tank Contractors lookup that can be filtered to Seminole County by contractor name, business name, or registration number, along with a separate public list of septic tank contractor enforcement actions - both free ways for a Sanford-area owner to check a company before signing a contract or booking a pump-out.

Pumping is regulated in Florida, not open to anyone with a truck: only a registered septic tank contractor or a state-licensed plumber may pump a septic tank, and they must hold an active service permit issued by the local county health department - DOH-Seminole for Sanford-area properties. Asking a pumper for their registration and current service permit is the simplest way to screen an unusually cheap quote. Source: Florida DEP - Septic Contracting FAQ
Pumping and repair near Sanford
Pumping looks like the one septic job anyone with a truck could do, but Florida regulates it: only a registered septic tank contractor or a state-licensed plumber may pump a septic tank, and the company must hold an active service permit issued by the local county health department - DOH-Seminole for Sanford-area properties. Asking for the registration and the current service permit is the fastest way to screen a suspiciously cheap quote, and the septic pumping cost guide covers what a routine pump-out should include at each price level.

Septic work itself is a registered trade with a public paper trail. The Florida Department of Health publishes a searchable Septic Tank Contractors lookup - filterable to Seminole County by contractor name, business name, or registration number - along with a separate list of septic tank contractor enforcement actions. Both are free, and a two-minute check of the registration and the enforcement list before signing a contract is the closest thing to a background check a Sanford-area owner can run on a septic company.

Repairs go through the health department here: OSTDS repair permits and inspections for Sanford run through DOH-Seminole's Environmental Public Health office at 130 San Carlos Ave., and since July 1, 2022 an owner or contractor may instead hire a licensed private provider inspector to speed the timeline - though under the amended state rule a master septic tank contractor may not inspect their own repair, and every private-provider report carries a $35 review fee. One replacement wrinkle is specific to this area: on impacted Wekiwa/Rock Springs basin lots of one acre or less, a new system must be an enhanced nitrogen-reducing (ENR) design that cuts nitrogen by at least 65%, so if a failing system needs full replacement rather than repair, ask DOH-Seminole early whether the ENR requirement applies to your lot - and whether Seminole County's Septic Upgrade Incentive Program can offset part of the cost. The septic repair cost guide and the emergency septic repair guide break down what the work itself should cost. Source: FDEP - Private Provider Inspections of OSTDS
