Proper placement of wells and septic systems is critical for protecting Florida’s drinking water and environment. The 2025 Florida regulations outline clear minimum distances between wells, septic tanks, drainfields, and property features to ensure groundwater safety. For example, private potable wells must be at least 75 feet from septic systems, while public potable wells serving more than 2,000 gallons per day require a 200-foot separation. Septic systems must also maintain setbacks such as 5 feet from buildings and property lines and 75 feet from surface or tidal waters.

In addition to horizontal setbacks, Florida requires at least 24 inches of vertical separation from the drainfield to the water table, soil suitability evaluations, and a 50% reserve drainfield area for future needs. A valid septic permit from the county health department is required before installation, including site evaluations and post-installation inspections. Local jurisdictions may enforce stricter rules—particularly in sensitive areas such as spring protection zones or the Florida Keys. By following Chapter 62-6, F.A.C., working with licensed professionals, and consulting local ordinances, contractors and homeowners can ensure new systems are compliant, efficient, and protective of Florida’s water resources. Click here for more information.
