Announcing Draft Bill 97304: Florida Building Water Safety Protocol for Mitigating Legionella Risk

Florida’s reputation is built upon its coastal assets, vibrant tourism sector, and inviting climate that attracts millions of residents and visitors annually. However, the state’s warmth and humidity present an ongoing challenge: building water systems require consistent monitoring, maintenance, and documentation to mitigate potential risks.

The Water Safety Association of Florida (WSAF) introduces Draft Bill 97304, which outlines a proposed statewide framework titled the Florida Building Water Safety Protocol. This initiative aims to systematically reduce preventable exposures linked to Legionella in building water systems by establishing uniform standards for tracking and management of high-risk systems throughout the state.

About Legionella and Public Health Concerns

Legionella refers to a bacteria capable of proliferating within water systems under specific environmental conditions. Inhalation of aerosolized water droplets containing Legionella may lead to Legionnaires’ disease, a serious pneumonia variant. Those most at risk include older adults, immunocompromised individuals, and persons with certain underlying health conditions.

The primary target is not standard residential plumbing, but rather large, intricate water systems servicing a broad population, such as those found in hospitals, hotels, high-rise buildings, senior living communities, and expansive campuses.

Key Provisions of Draft Bill 97304

Draft Bill 97304 sets forth minimum statewide requirements for three system categories frequently associated with elevated risk when inadequately maintained:

• Cooling towers utilized in major building air-conditioning systems
• Domestic water holding tanks employed for large-scale water storage
• Supplemental disinfection systems integrated into drinking water infrastructure

Summary of Proposed Actions

The bill establishes a practical safety protocol centered on several foundational elements:

• Statewide electronic registration system for covered systems to facilitate oversight and assign responsibility.
• Mandated routine monitoring and reporting, including bacteriological assessments and Legionella culture sampling, enabling prompt detection of issues.
• Defined response procedures for test results surpassing specified thresholds to ensure timely and consistent action.
• Obligatory notification to county health departments, complemented by public notification mechanisms when Legionella levels exceed trigger points.
• Introduction of disinfection and water-efficiency standards for cooling towers, featuring metering, automated controls, drift reduction, and overflow alarms.
• Requirement for independent inspections and annual certifications affirming compliance with necessary measures.
• Compulsory record retention for a minimum of three years to support accountability and expedite public health interventions as required.

The intent is to create a consistent statewide standard, allowing responsible parties to demonstrate effective practices while minimizing gaps in regulatory oversight.

Relevance to Florida

Florida’s unique risk profile includes a significant concentration of facilities occupied or frequented by vulnerable population such as  hospitals, rehabilitation centers, and senior living communities as well as large hospitality and residential structures serving thousands daily.

At present, the state lacks an integrated, statewide framework uniting registration, routine reporting, and standardized response protocols for these higher-risk systems. Draft Bill 97304 seeks to address this deficiency through a proactive prevention-based approach.

Implementation Strategy: The Clearinghouse Model

WSAF also proposes a Florida Building Water Safety Clearinghouse to serve as a centralized registry and data repository, enhancing compliance, transparency, early-warning capabilities, and public health coordination without imposing excessive bureaucratic complexity.

The overarching objective is to render state water safety initiatives more systematic, measurable, and manageable.

Proposed Timeline

The draft legislation incorporates a phased implementation schedule to allow adequate preparation for building owners:

• July 1, 2026: Protocol becomes effective
• Nov 1, 2026: Annual certification requirement commences
• July 1, 2027: Initiation of 90-day reporting cycle
• Sep 1, 2027: Maintenance plans mandated for existing cooling towers
• Dec 31, 2027: Final deadline for variance requests (maximum extension of 90 days)

Note: All dates and details remain subject to further legislative refinement.

Next Steps: Collaborative Approach

Effective implementation of building water safety protocols necessitates collaborative efforts among public health officials, facility managers, healthcare providers, hospitality operators, homeowners’ associations, engineers, laboratory specialists, water treatment professionals, and policymakers. WSAF is actively developing this coalition to ensure that the finalized framework is both practicable for property owners and valuable for public health outcomes.

Florida benefits from a skilled workforce already engaged in cooling tower maintenance, waterborne pathogen testing (including Legionella control), system disinfection, and inspection services; such expertise will underpin the establishment of effective statewide standards.
