Performance Based Treatment
Systems (PBTS) are the next step when there are more
restrictions than a standard septic system or aerobic treatment
unit (ATU) can accommodate.
Performance based treatment systems are defined by the Florida
Department of Health (FDOH) 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 three levels of PBTS are:
Secondary Treatment, Advanced Secondary Treatment, and 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
a homeowner, you are responsible for maintaining your PBTS in
accordance with the laws of Florida. For the entire life of the
system, the Health Department requires the following:
operating permit, and a
maintenance contract between the home owner and an approved
maintenance entity for the system.
samples are required to be submitted by the maintenance
entity every six months (residential) and every 3 months
(commercial) along with 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.
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 home owner, it is
essential to follow all of the maintenance requirements for your
PBTS to ensure a properly functioning system. This will prolong
the life of your system and maintain cleaner drinking water,
ground water, nearshore water, and offshore water.
