Onsite sewage treatment and disposal systems (OSTDS), commonly referred to as septic systems, are a safe and effective means of wastewater disposal for 30% 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% of Florida’s drinking water. 

Since 2021, the Florida Department of Environmental Protection (DEP) has been responsible for implementing the Florida Statutes and regulations applicable to OSTDS. However, some county health departments, such as DOH-Clay, will continue to inspect and issue permits for septic systems until the transfer to DEP is complete.

Construction Permits

To apply for a permit, download and complete an application (DEP 4015) and submit it, along with a site plan, a building floor plan, and the required application fee to DOH-Clay. You will need a qualified professional to complete a site evaluation to determine the conditions on your property. If you wish, DOH-Clay can perform the site evaluation for a fee, or you can hire a private provider.

The total permitting fee (including any county fees) is based on the type of system needed for your property and any required services. The information in your application, site plan, building plan and site evaluation will allow us to determine the construction needs for the system to serve your property.

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 in Clay County.
