Every record Tank411 sells is compiled from Florida public records, reproduced accurately, attributed to its source, and dated. Tank411 is not affiliated with any government agency, and nothing we publish is a statement by the State of Florida.
Our sources
- Florida Department of Health — the Florida Water Management Inventory, the state’s parcel-level record of how each property manages wastewater. We sell only parcels the inventory classifies as known septic — supported by a permit or utility record, not modeled or inferred.
- Florida Department of Revenue — the county final tax rolls (owner name, mailing address, property address, year built, appraised value, land use).
- Florida Department of Environmental Protection — the public registry of septic contractors, used only for our own outreach to those businesses.
Why everything is dated “as of”
We compile from the newest releases the state has published, and each county’s buy page states the tax-roll year and the inventory’s publication date. Public records lag reality: owners change, homes connect to sewer, and inventories are updated on each county’s own schedule. A list is a dated snapshot of the official record — the authoritative, current record always lives with the state and the county.
Estimates, not inspections
We make no claim about the condition of any septic system. A listing means the state’s records indicate the property is served by a septic system and the home was built at least 15 years ago — nothing more. In particular:
- System age is an estimate derived from the home’s year built. Systems older than about 40 years are reported as “40+” because the original system has usually been serviced or replaced by then.
- A listing is not a statement that a system is failing, damaged, non-compliant, or in need of service, and it is not an inspection, assessment, or opinion about any property.
- Our lists are marketing and planning data for septic service businesses — they identify homes where septic service is plausible, not homes where it is needed.
Known coverage limits
The state inventory does not classify homes built after roughly its own creation date, so the newest construction is under-represented — irrelevant to our product, which only includes systems 15+ years in the ground, but worth stating. Matching inventory parcels to tax-roll parcels is imperfect in a small share of cases, so a county list may omit some qualifying homes. We prefer omission to fabrication: no field is inferred, appended, or filled in beyond what the records contain.
Corrections and removals
If you believe a record is inaccurate, or you want your property excluded, use our dispute & correction process. We review against the official record and correct, annotate, or remove the listing where warranted. We never charge anyone a fee to remove, correct, or modify a listing.
