Water Management Plans

Water Management Plans That Actually Prevent Legionella 

If your building water system has warm zones, low-flow areas, storage, or aerosol-producing equipment, Legionella risk isn’t hypothetical—it’s operational. A Water Management Plan (WMP) gives your team a clear, documented playbook to reduce risk, respond fast, and prove you’re in control.

The Hidden Risk: “We’re doing maintenance” ≠ “We’re controlling Legionella”

Many facilities think they’re covered because they have routine flushing, temperature checks, or a vendor “binder.” But Legionella thrives in gaps—dead legs, mixed-temperature zones, underused wings, and inconsistent documentation. 

If any of this is true, you’re exposed:

Your “plan” is outdated, incomplete, or spread across spreadsheets and emails 

Corrective actions aren’t clearly defined (or tracked when limits slip) 

You’re relying on tribal knowledge (“only Jim knows how we do this”) 

If an incident happened tomorrow, you couldn’t quickly prove what was done—and when 

You don’t have a clear flow diagram of the systems you’re managing 

ChemREADY Water Safety & Management Plans

A Water Management Plan is a living document that defines your building-specific risks, control limits, monitoring routines, and exactly what to do when limits are out of range. We help you build it correctly, then help you run it.

Clear Program Structure & Ownership

A compliant WMP starts with a defined team and clear responsibilities. We help you identify who owns each part of the program, outline system descriptions, and map every water system in scope with easy-to-follow flow diagrams.

Legionella Water Testing

Comprehensive Risk Assessment

We evaluate each water system to pinpoint where Legionella or other pathogens could grow. Every risk point is documented, prioritized, and tied directly to control measures and monitoring requirements.

Control Measures + Monitoring Plans

Your WMP includes detailed control limits for temperature, disinfectant levels, and system performance. We provide routine monitoring steps, corrective actions for out-of-range conditions, and practical instructions your team can follow.

Verification & Validation

To ensure your WMP works long-term, we outline ongoing verification steps (are tasks being completed?) and validation strategies (is the program effective?), including optional support for testing and documentation management.

Our Approach: Clear, Trackable, Defensible

If your plan isn’t easy to maintain, it won’t stay current. We’ll help you modernize execution so your team can keep up. 

How it Works

Assess The System

We review your building water systems and identify where Legionella risk is most likely to occur.

We document control limits, monitoring points, corrective actions, responsibilities, and communication rules—tailored to your facility.

We help your team implement the plan so it functions in real life—not just on paper.

Ongoing review, documentation checks, and updates as your building usage and risks change.

Who Typically Needs a Water Management Plan?

ASHRAE 188-2021 identifies multiple building types and risk profiles where a WMP is recommended/expected—especially facilities with centralized systems and vulnerable populations. 

Common examples include: 

  • Multi-unit buildings with centralized potable hot water 
  • Buildings over 10 stories 
  • Healthcare facilities and facilities serving higher-risk occupants 

And systems like: 

  • Potable water systems 
  • Cooling towers / evaporative condensers 
  • Decorative fountains, humidifiers, misters, spas 

Make the Plan Easy to Run (Not Just Easy to Write)

A plan is only as good as your ability to maintain it. ChemREADY partners with HC Info to support LAMPS (Legionella Assessment and Management Plan Support)—a cloud-based system designed to keep documentation organized, updates simple, and audits less painful.
