Onsite Sewage Treatment & Disposal System (OSTDS)

Environmental Health

OSTDS Construction 

The main goal of this program is to protect public health by eliminating the potential for the spread of infectious disease, by protecting the ground and surface water from improperly built or maintained onsite sewage treatment and disposal systems.  Through the OSTDS Construction program, our office 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 Walton County must first obtain a permit from our office.  In addition, any changes to original permitted conditions require approval from our office.  Systems producing a domestic sewage flow of more than 10,000 gallons per day (gpd) or a commercial sewage flow of more than 5,000 gpd are regulated by the Department of Environmental Protection.

OSTDS Operating Permits 

Aerobic Treatment Unit (ATU) / Performance Based Treatment System Operating Permits

Aerobic Treatment Units (ATU) are septic systems that achieve enhanced sewage treatment by promoting aerobic bacteria growth.  Most ATUs promote the growth of aerobic bacteria by introducing oxygen into the treatment receptacle via a small air compressor or blower unit.  For a list of ATUs approved for use in Florida please visit http://www.doh.state.fl.us/environment/ostds/products/products.html.

Commercial Septic System / Industrial or Manufacturing (IM) Septic System Operating Permits

Commercial septic systems are those serving a facility that produces non-toxic, non-hazardous wastewater but have the potential of generating higher strength wastewater flows than domestic wastewater.  Examples of establishments included in this definition are commercial and industrial food operations, commercial laundry facilities with no more than 4 machines, beauty salons, and animal holding facilities.

As per Florida Statute 381.0065(4) an operating permit must be obtained prior to the use of any onsite sewage system serving an establishment that produces commercial waste.  The operating permits are valid for one year from the date of issuance and must be renewed annually.  To obtain an operating permit within Walton County, an Application for Onsite Sewage Treatment and Disposal System Operating Permit and Business Survey must be completed and submitted to the Brevard County Health Department with the applicable fees.  Operating permits are not transferrable from one owner to the next.

Industrial or manufacturing zoned or equivalent use septic systems are those receiving industrial, hazardous, or toxic sewage waste that is not otherwise defined as domestic sewage or commercial sewage.  Wastewater carried off by floor drains, utility sinks and equipment drains located in buildings in industrial or manufacturing areas, and wastewater from car and truck washes are included in this definition.

As per Florida Statute 381.0065(4)(i)2., each person who owns or operates a business or facility in an area zoned or used for industrial or manufacturing purposes, or its equivalent, or who owns or operates a business that has the potential to generate toxic, hazardous, or industrial wastewater or toxic or hazardous chemicals, and uses an onsite sewage treatment and disposal system that is installed on or after July 5, 1989, must obtain an annual system operating permit from the department. A person who owns or operates a business that uses an onsite sewage treatment and disposal system that was installed and approved before July 5, 1989, need not obtain a system operating permit. However, upon change of ownership or tenancy, the new owner or operator must notify the department of the change, and the new owner or operator must obtain an annual system operating permit, regardless of the date that the system was installed or approved.  The operating permits are valid for one year from the date of issuance and must be renewed annually.  To obtain an operating permit in Walton County, an Application for Onsite Sewage Treatment and Disposal System Operating Permit and Business Survey must be completed and submitted to the Walton County Health Department with the applicable fees.  Operating Permits are not transferrable from one owner to the next.
