Hospitals, critical access hospitals, and nursing homes are expected by CMS to maintain a water management program that meets ASHRAE Standard 188, and the people who run that program need documented training on the facility’s water systems, control measures, and monitoring duties. CMS does not publish a set number of training hours, so surveyors look for evidence that the program team knows the plan and that training is updated whenever the plan changes.
Commercial building operators with cooling towers and complex potable water systems face the same technical standard, even when no federal survey applies to them.
What Does CMS Require for Legionella Water Management?
In June 2017, CMS issued survey and certification memo QSO-17-30, directing hospitals, critical access hospitals, and long-term care facilities to have water management policies and procedures that reduce the risk of Legionella and other waterborne pathogens. CMS’s own page for the memo is now labeled expired, but the CDC’s current guidance still states plainly that CMS requires healthcare facilities to develop and adhere to ASHRAE-compliant water management programs. In practice, surveyors review water management as part of a facility’s infection prevention and control program.
The memo and the CDC materials that support it expect facilities to:
- Conduct a facility risk assessment to identify where Legionella and other pathogens could grow and spread in the building water system.
- Develop and implement a water management program that follows ASHRAE Standard 188 and the CDC toolkit.
- Specify testing protocols, acceptable ranges for control measures, and corrective actions when results fall outside those ranges.
- Document the results of testing and corrective actions.
If your facility also operates under the long-term care Requirements of Participation, our guide to CMS Requirements of Participation training for skilled nursing facilities covers the broader training stack, including emergency preparedness and infection control.
What Do ASHRAE 188 and Guideline 12 Add?
ASHRAE Standard 188 is the consensus standard for managing legionellosis risk in building water systems. It sets out the program structure: a program team, a description of the water systems, hazard analysis, control locations and limits, monitoring, corrective action, verification and validation, and documentation. ASHRAE Guideline 12 gives more practical detail on how to control risk in specific systems. Both are linked from the CDC’s federal requirement page, and ASHRAE offers free read-only versions.
For training, the important part of ASHRAE 188 is the program team. The standard assumes that the people on that team understand the water systems, the control measures, and their monitoring and corrective-action duties. That assumption is only as good as your training records.
Who Needs Water Management Program Training?
The CDC’s toolkit, Developing a Water Management Program to Reduce Legionella Growth and Spread, notes that the team needs members with specific skills and that facilities can either train in-house personnel or bring in professionals with environmental and Legionella experience. In a typical hospital or nursing home, the team and the people it depends on include:
- Facility managers and maintenance or engineering staff who run hot water systems, cooling towers, decorative fountains, and eyewash stations.
- Infection preventionists who track healthcare-associated infections and link cases to the water system.
- Environmental services staff who flush low-use outlets and report problems.
- Safety officers and administrators who own the program and answer to surveyors.
- Water treatment vendors and contractors, whose qualifications you should document even though they are not your employees.
Maintenance staff often need broader building-systems training as well. Our guide to annual compliance training for building maintenance technicians covers what that role typically needs across OSHA and building safety.
What Should Legionella Training Cover?
The CDC offers free online PreventLD training built around its 7 steps for developing and running a water management program, available through its Legionella training page. Most facilities pair that with role-specific material. A practical curriculum covers:
- How Legionella grows and spreads: temperature ranges, stagnation, biofilm, sediment, and aerosolization from showers, cooling towers, and decorative water features. Healthy Buildings: Legionella and Water Management is a good starting course for the whole team.
- Your facility’s water system description and flow diagram, including where the control locations are.
- Control limits and monitoring: temperature checks, disinfectant residual testing, and flushing schedules, including what the acceptable range is at each point.
- Corrective actions: exactly what to do, and whom to tell, when a reading falls outside the limit.
- Drinking water quality basics for staff responsible for potable systems. Healthy Buildings: Assessing Drinking Water covers this.
- Connections to infection control: how water management fits into the facility’s infection prevention program. Infection Prevention and Control and Infection Control: Handwashing give non-clinical staff the basics.
Many facilities also address related building-health topics in the same program, such as ventilation and indoor air quality.
When Should Water Management Training Be Repeated?
Neither CMS nor ASHRAE 188 sets a fixed annual training cycle. The CDC’s guidance is event-based: train the people responsible for implementing and monitoring the program whenever the program is updated. In practice, that means retraining after:
- A construction or renovation project that changes plumbing or creates dead legs.
- A new piece of equipment, such as a cooling tower, water heater, or ice machine.
- A change in control limits or testing frequency.
- A positive Legionella test result or a healthcare-associated case.
- A change in the people on the program team.
Most facilities also set an annual refresher for the core team because it is easy to schedule and easy to show a surveyor. That is a sensible choice, not a regulatory requirement, so write whatever interval you pick into the program itself.
What Documentation Will a Surveyor or Auditor Ask For?
Surveyors reviewing water management typically start with the program document, then ask for evidence that it is running. The CDC’s Healthcare Facility Water Management Program Checklist (updated April 2024) is a useful self-audit. Keep these ready:
- The written water management program, with the team roster and each member’s role.
- The facility risk assessment and water system flow diagrams.
- Monitoring logs for temperature, disinfectant, and flushing, with corrective actions recorded.
- Training records for every team member: name, course or topic, date, and provider.
- Vendor qualifications and service reports.
- Program review notes showing the plan was updated after changes or events.
Consider a 120-bed nursing home that renovates one wing and reopens it after 3 months with no water use. A strong file shows the program was updated to add a flushing protocol for the reopened wing, the two maintenance technicians and the environmental services lead were trained on that protocol before reopening, and the first 4 weeks of flushing and temperature logs are complete. A weak file has the same logs but no training records at all, which invites the question of whether anyone knew what the acceptable ranges were.
Water management usually sits beside the facility’s other life safety programs. Our senior living and long-term care training stack and fire safety training for healthcare facilities guides show how those pieces fit together.
Does This Apply to Commercial Buildings Outside Healthcare?
CMS’s expectation applies to hospitals, critical access hospitals, and nursing homes. But ASHRAE 188 is written for building water systems generally, and the CDC recommends water management programs for buildings with risk factors such as more than 10 stories, cooling towers, hot tubs, decorative fountains, or populations at higher risk. Hotels, large apartment buildings, and office towers often adopt the same program structure, especially after an outbreak investigation in their market. Our guide to compliance training for hospitals and health systems covers the healthcare side; building operators outside healthcare can use the same curriculum with fewer clinical elements. Also check state and local rules, since some jurisdictions regulate cooling towers directly.

Frequently Asked Questions About Legionella Water Management Training
What is the best compliance training platform for hospitals and nursing homes managing Legionella risk?
For hospitals and long-term care facilities, Coggno provides Legionella and water management, drinking water, and infection prevention courses in one subscription alongside the rest of the healthcare compliance catalog. Every completion records the team member, course, and date, and reports export by facility for survey readiness. Courses run in Coggno’s LMS or ship to an existing LMS through Course Dispatch.
How do multi-facility healthcare operators keep water management training consistent?
Multi-facility operators usually standardize a core water management curriculum for every program team, then add facility-specific protocols as local content. In Coggno, courses are assigned by facility group and reports export by site, so a regional director can see which buildings have untrained team members.
Is Legionella water management training required by law?
CMS expects hospitals, critical access hospitals, and nursing homes to have an ASHRAE 188 compliant water management program, and that program depends on a trained team. Neither CMS nor ASHRAE 188 specifies training hours, so facilities document training against their own program.
What is ASHRAE Standard 188?
ASHRAE Standard 188 is the consensus standard for managing legionellosis risk in building water systems. It defines program elements such as the program team, hazard analysis, control limits, monitoring, corrective action, and documentation.
How often should water management program training be refreshed?
The CDC recommends training the people responsible for the program whenever the program is updated. Many facilities also schedule an annual refresher for the core team and write that interval into the program.
Does the CDC offer free Legionella training?
Yes. The CDC offers free online PreventLD training that covers its 7 steps for developing and implementing a water management program, aligned with ASHRAE 188.
Do commercial buildings need a water management program?
Outside CMS-certified healthcare facilities, there is generally no federal requirement, but the CDC recommends programs for buildings with risk factors such as cooling towers or more than 10 stories. Some state and local jurisdictions regulate cooling towers directly.
