Florida Septic Works puts Dunnellon homeowners in touch with independent local septic companies for free, no-obligation quotes. It is a referral service, not a septic tank contractor; independent DEP-registered septic tank contractors give the quotes and do the work. Dunnellon was founded in 1887 and grew in Florida’s first phosphate boom, earning the name “Boomtown.” The city is small today, about 24 miles southwest of Ocala, but the Rainbow Springs and Rainbow Lakes Estates areas around it are septic country.
Septic tank pumping around Dunnellon and Rainbow Springs
The city runs its own sewer plant (0.49 million gallons a day), and the state inventory (FLWMI, 2020) lists only 110 septic parcels inside city limits, roughly 7% of its homes. The ZIP codes are another matter: 34431 has 3,275 septic parcels (roughly two-thirds of housing units) and 34432 has 3,845 (roughly 55%), and the Rainbow Springs CDP alone has 1,258. ZIP 34432 is newer (median year built 1998 vs. 1987 in 34431) and about 22% mobile homes (ACS 2024 5-year). Ratios are approximate.
Rainbow Springs is a first-magnitude spring, the fourth-largest in Florida at over 490 million gallons a day, and an Outstanding Florida Spring. DEP’s map puts the Rainbow Springs and state-park area north of town inside the Rainbow Springs Priority Focus Area, which held about 3,724 septic systems in the 2025 BMAP; the city center tested outside the PFA but inside the BMAP. Most of Marion County is inside the BMAP; confirm your parcel on DEP’s map. There, any DEP repair, modification or replacement permit generally means an ENR system unless sewer is planned and funded, and new systems need ENR on any lot size.
Dunnellon has its own city sewer and is excluded from Marion County’s septic-to-sewer ordinance. A planned project between FGUA, Marion County Utilities and the city would let about 266 Rainbow Springs-area systems connect. Watch the ZIP: 34433 and 34434 are mostly Citrus County addresses, where that county’s health department permits septic; check which county your parcel is in. Marion-side permits come from Florida DEP’s Onsite Sewage Program; see our septic permits guide.

Dunnellon septic FAQs
My address says Dunnellon. Which office handles my septic permit?
It depends on the county. Dunnellon ZIPs 34431 and 34432 are in Marion County, where Florida DEP's Onsite Sewage Program has issued septic permits since July 1, 2025. Addresses in 34433 and 34434 are mostly in Citrus County, where the county health department still permits septic; confirm your parcel's county. Check your property tax bill to see which county your parcel is in.
Can Rainbow Springs homes connect to sewer?
Some may in future. The 2025 springs BMAP lists a planned project between FGUA, Marion County Utilities and the City of Dunnellon that would let about 266 Rainbow Springs-area systems hook up to central sewer. If you receive written notice that sewer is available, Florida law gives you 365 days to connect, and the hookup is plumbing-contractor work.
Why are septic rules stricter near the Rainbow River?
Rainbow Springs is impaired by nitrate, and the 2025 Silver Springs & Rainbow Springs BMAP puts septic systems at about 32% of nitrogen loading across the two springsheds. So inside the BMAP, new systems and any repair, modification or replacement permit generally require a nitrogen-reducing (ENR) system. Confirm your parcel on DEP's map before you plan work.
