The Onsite Sewage Program has moved to the Florida Department of Environmental Protection
NOTE: Effective July 1, 2021, the Florida Department of Environmental Protection (DEP) is responsible for implementing the Florida Statutes and regulations applicable to OSTDS. Under Florida's Clean Waterways Act of 2020, the county health department offices will continue to do the permitting and inspection for septic tanks; please continue to work with them for all of your permitting-related needs. If you have questions, please contact OSTDS_Feedback@FloridaDEP.gov.
Onsite sewage treatment and disposal systems, commonly referred to as septic systems, can be a safe and effective means of wastewater disposal for 30 percent of Florida’s population. The OSTDS program ensures that the OSTDS is properly designed, constructed, and maintained through permitting and inspection and contributes to safe ground water, which provides 90 percent of Florida’s drinking water. In Monroe County, central sewer is almost universally available, and all locations where sewer is available must be connected. Septic systems are rare in the Florida Keys now, and the ones that are here are required to be Performance Based Treatment Systems.
The governing authorities for this program and all forms can be found at https://floridadep.gov/water/onsite-sewage.
OSTDS Operating Permits
Operating permits are required for aerobic treatment units (ATU), performance based treatments systems (PBTS), commercial septic systems, and industrial or manufacturing zoned (or equivalent) septic systems.
