Water Safety for Cooling Towers, Domestic Water Holding Tanks, and Supplemental Disinfection Systems
HB 1377 creates a new part of chapter 386, Florida Statutes, establishing a statewide regulatory program for cooling towers, domestic water holding tanks, and supplemental disinfection systems. The bill is aimed at preventing Legionella growth and legionellosis by requiring owners to register covered systems with the Department of Health, maintain a written maintenance program and plan, conduct routine bacteriological and Legionella sampling, and keep records of inspections, disinfection, and corrective actions. It also requires periodic reporting through a statewide electronic system and makes certain data publicly available as appropriate.
The bill sets detailed operational standards for cooling towers, including minimum sampling intervals, response thresholds for bacteriological and Legionella results, mandatory disinfection and remediation steps, inspection schedules, certification requirements, and water-efficiency measures such as meters, conductivity controls, and drift eliminators. It also authorizes the Department of Health and county health departments to inspect properties, require additional testing when cases may be associated with a cooling tower, and treat noncompliance as a nuisance subject to civil and criminal penalties. The act takes effect July 1, 2026, with some compliance deadlines extending into 2027.
The bill would add new statutory duties for owners and operators of cooling towers, domestic water holding tanks, and supplemental disinfection systems, while expanding the Department of Health’s oversight and enforcement authority. It creates registration, reporting, inspection, certification, and recordkeeping obligations, and it authorizes county health departments and the department to access properties, require testing, issue waivers, and approve short variances through December 31, 2027. It also references existing standards such as ANSI/ASHRAE 188-2018 and Florida pesticide and environmental laboratory certification requirements, thereby tying the new chapter to multiple existing regulatory frameworks.
No committee transcripts or vote history were provided, so there is no recorded legislative debate or roll-call evidence to assess support or opposition. Based on the bill text alone, the measure appears to be framed as a public-health and safety initiative focused on preventing Legionella exposure and improving maintenance of building water systems. The structure of the bill suggests a strong regulatory approach rather than a voluntary program.
The main likely points of contention are the compliance burden and enforcement scope. Owners of cooling towers and related systems would face recurring sampling, inspections, reporting, certification, and equipment requirements, which may raise cost and administrative concerns, especially for smaller property owners or facilities with older systems. Another possible issue is the breadth of public-health authority, including public notification, property entry for inspections, nuisance determinations, and civil and criminal penalties for ongoing violations. The bill does provide limited waivers and temporary variances, which may be intended to address implementation concerns.
