Performance Based Treatment Systems

Performance Based Treatment Systems (PBTS) are an option when a standard system design will not fit.

PBTS are defined by the Florida Department of Health (DOH) as:

“a specialized onsite sewage treatment and disposal system designed by a professional engineer with a background in wastewater engineering, licensed in the state of Florida, using appropriate application of sound engineering principles to achieve specified levels of CBOD5 (carbonaceous biochemical oxygen demand), TSS (total suspended solids), TN (total nitrogen), TP (total phosphorus), and fecal coliform found in domestic sewage waste, to a specific and measurable established performance standard.”

If a site restricts home construction because of setbacks or authorized sewage flow, a system can be designed by an engineer to meet strict levels of effluent pollutant reductions.

The closure of the construction permit, transition to the opening of the annual operating permit.

The PBTS application fee is $465.00. Pay online by visiting MyFloridaEHPermit.com.

The three levels of PBTS are:

• Secondary Treatment
• Advanced Secondary Treatment
• Advanced Wastewater Treatment

These systems can include ATUs, or tanks which percolate effluent down through a medium such as peat moss or synthetic material.

Some additions which increase effluent treatment are:

• Chlorinator/Dechlorinators
• UV Lights, and/or
• Effluent recirculation

Recorded Notice that must be filed with the clerk of courts notifying subsequent owners of the use of the PBTS on the property.

Homeowners are responsible for maintaining PBTS in accordance with Florida law. For the entire life of the system, DOH requires the following:

• A valid operating permit, and
• A maintenance contract between the homeowner and an approved maintenance entity for the system.
• Laboratory samples are required to be submitted by the maintenance entity:
  • Every six months for residential properties.
  • Every 3 months for commercial properties.
  • In both residential and commercial properties, they must include an inspection/maintenance report.
  • Different sample levels are required depending on the level of PBTS and the reductions or increases the system needs to take advantage of, due to the specific lot conditions.
  • Samples are the proof that the reductions are warranted. 

Important Note for Homeowners:

For the system to function properly it is important to be aware of what and how much goes down the drain. Increased waste strength could require added treatment and maintenance.

As a homeowner, it is essential to follow all the maintenance requirements for the PBTS to ensure a properly functioning system. This will prolong the life of the system and maintain cleaner drinking water, ground water, nearshore water, and offshore water.
