Legionella Water Management Plans
Custom WMPs Built for Your Facility.
WMA develops practical, defensible Legionella Water Management Plans aligned with ASHRAE 188, CMS requirements, and applicable state regulations — written in language your team can actually use.
What Is a WMP?
It's more than a document- it's a working program
A Legionella Water Management Plan is a documented program that identifies the water systems in your facility that pose a risk for Legionella growth and transmission, establishes control measures for each, and defines how those controls will be monitored and maintained over time.
Regulatory bodies including CMS, accreditation groups (The Joint Commission, ACHC, DNV), and a growing number of state health departments now require healthcare facilities, senior living communities, and other high-risk buildings to have a written, implemented WMP. But compliance alone isn't the goal, a well-designed WMP is your best tool for actually preventing Legionnaires' disease.
WMA develops plans that are grounded in the specific conditions of your facility, not generic templates. We conduct a thorough on-site assessment, document your water systems, identify risk areas, and build a program your facilities team can realistically implement and sustain.
Regulatory Alignment
Plans built to the standards that matter
The foundational industry standard for Legionella risk management in building water systems. WMA's plans are developed in full alignment with ASHRAE 188's requirements for hazard analysis, control measures, and monitoring.
The Centers for Medicare & Medicaid Services requires all Medicare- and Medicaid-certified facilities to have a water management policy and program. WMA's plans are designed to satisfy CMS survey requirements.
Many states have enacted their own Legionella WMP requirements — particularly for healthcare and senior living. WMA stays current on state-level regulations and ensures your plan meets applicable local requirements.
Healthcare accreditation groups' standards require accredited hospitals and healthcare organizations to manage Legionella risk. WMA's plans support these groups' compliance and are written to withstand survey scrutiny.
Plan Components
What your WMP includes
Facility & Water System Description
A documented inventory of all water systems, equipment, and features in your facility which are the foundation of any defensible WMP.
Hazard Analysis
Identification of conditions and locations where Legionella could grow or spread, based on a systematic review of your water systems and facility operations.
Control Measures
Specific, actionable controls for each identified hazard. Including temperature management, disinfectant residual maintenance, and physical system controls.
Monitoring & Corrective Actions
A defined monitoring schedule with clear trigger levels and corrective action procedures so your team knows exactly what to do when a parameter falls outside range.
Verification & Validation
Procedures for confirming that control measures are working as intended, including Legionella culture testing protocols and documentation requirements.
Team Roles & Responsibilities
Clear assignment of responsibilities to specific roles within your organization so accountability is built into the program from day one.
Beyond the Plan
Implementation and ongoing support
Developing a WMP is only the beginning. WMA provides staff training to ensure your team understands the plan and their roles within it, and we remain available as a resource throughout implementation.
We conduct annual plan reviews to keep your WMP current as your facility evolves, regulations change, and new guidance is published. We also provide support when monitoring results trigger corrective action so you're never navigating a positive Legionella result alone.
Included with every WMP
- Staff training on plan roles and procedures
- Annual WMP review and update
- Corrective action support for positive results
- Regulatory update monitoring
- Complimentary Legionella consulting for clients
