ATU & PBTS Maintenance Activity Reporting System (MARS)

Under Florida Law, Aerobic Treatment Units (ATU) and Performance-Based Treatment Systems (PBTS) must have a maintenance contract with a Service Contractor permitted to service these systems. These systems must be inspected and maintained two or more times a year depending on its permitted use. Operators of these systems are required to obtain and record the maintenance contract for their system on this website. Permitted Service Contractors that perform activities under the contract on these systems are required to record them on this website.

If you are a Permitted Operator contracting with a Permitted Service Contractor, or you perform maintenance and inspections for ATU or PBTS systems under contract and do not have access to enter contracts or activities on this site please contact your Florida County Health Department for assistance.
