The bill amends section 403.814 of the Florida Statutes to establish a framework for general permits related to distributed wastewater treatment systems (DWTS). It introduces definitions for key terms, including "distributed wastewater treatment system" and "distributed wastewater treatment unit" (DWTU), which is described as an advanced onsite closed-tank system designed for efficient wastewater treatment. The Secretary of Environmental Protection is authorized to grant general permits for replacing existing onsite sewage treatment systems with DWTS under specific conditions, including ownership and operational requirements.

Additionally, the bill allows for the installation of DWTUs to proceed without further action from the Department of Environmental Protection, provided that the permittee submits a notification at least 30 days prior to installation. This notification must confirm that the DWTU has been designed by a Florida-registered professional and meets various operational and environmental standards. The permittee is also required to conduct monthly reporting, annual inspections, and ensure compliance with performance standards. The act is set to take effect on July 1, 2025.
