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 defines key terms such as "distributed wastewater treatment system" and "distributed wastewater treatment unit" (DWTU), which is characterized 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 the requirement for permittees to notify the department at least 30 days prior to installation.

Additionally, the bill outlines the conditions under which the installation of DWTUs can proceed without further action from the Department of Environmental Protection, provided that certain criteria are met. These criteria include design capacity limits, discharge requirements, and compliance with public health and safety standards. Permit holders are also mandated to conduct monthly reporting, annual inspections, and maintain proper recordkeeping for the DWTUs. The act is set to take effect on July 1, 2025.
