Onsite Sewage

Roughly 30 percent of Floridians rely on Onsite Sewage Treatment and Disposal Systems (OSTDS) (also known as septic systems), to treat and dispose of household wastewater. This translates to about 2.5 million systems in operation in Florida discharging about 426 million gallons of wastewater per day to underlying soil and groundwater. Wastewater carries pathogens, nutrients (like nitrogen and phosphorus), and trace organic chemicals that may be harmful to human health and ecosystem function. Proper treatment of wastewater is crucial, and septic systems can be one means of effective treatment. Properly designed, constructed, and maintained systems protect Florida’s ground water which provides 90 percent of Florida’s drinking water.

Because of this important public health issue, any time a septic system is installed, repaired, altered, modified, or abandoned a permit is required by the Florida Department of Health. DOH-Brevard ensures these systems are properly designed and installed as required by Florida Administrative Code, Florida Statues, and Brevard County Ordinances through our permitting and inspection process.

OSTDS Construction Permits 

Through the Onsite Sewage Treatment and Disposal System (OSTDS) Construction program, the Florida Department of Health in Brevard County Environmental Health Services permits, regulates and inspects the construction of new systems, repairs and modifications to existing systems, existing system approvals and abandonments of systems. Anyone who plans to install, repair, modify or abandon an OSTDS in Brevard County must first obtain a permit from our office. In addition, any changes to original permitted conditions require approval from our office.

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.

OSTDS Service Permits 

Septic tank manufacturers, septage disposal services (septic tank pump trucks), septage stabilization and land application sites, temporary toilet services, and ATU maintenance entities require a service permit from the county health department. For more information, please visit our Service Permits page.

Voluntary Inspection and Assessment of Existing Septic Systems 

If the home you are buying is on a septic system you may request an inspection and assessment of the system. By law, only a state-licensed septic tank contractor or plumber or a certified environmental health professional can inspect and assess your septic system. The Homebuyer’s Guide to Septic Systems contains more information and frequently asked questions about the voluntary inspection procedures. The Voluntary Inspection and Assessment Report was created for the septic system inspector to use or to assist in creating their own report that meets the requirements of the Florida Statutes and Florida Administrative Code.
