The Importance of Waterborne Pathogen Control  

According to the CDC, reported cases of Legionnaires’ disease have grown by more than five times since 2000. And while Legionella makes the headlines, there are other dangerous pathogens that can cause problems in your building's water systems.

Pathogen control is important for compliance with industry standards, maintaining your organization's reputation, and avoiding possible litigation. (The average cost of a Legionella claim is $11MM). Most important though, is the prevention of an outbreak that could cause severe illness or even the loss of human life.

Having a water safety management plan and the support of a trusted water treatment partner is critical to protect your facility and the people inside. We can help.

Is Your Building At Risk for Legionella? 

The simple truth is that every building with indoor plumbing can harbor Legionella, and no amount of Legionella growth is safe. Still, there are certain factors that put you at greater risk including:

  • Building size – 10 stories or higher
  • Building features – centralized hot water, cooling towers, decorative fountains, hot tubs, etc.
  • Building occupants – age and health factors

The Legionella bacteria exists naturally in freshwater sources such as lakes and streams, but once it enters a closed water system, it can grow and pose a serious threat to the people in your building.

Cooling towers, expansion tanks, water filters, shower heads and hoses, pipes, valves, and fittings are common locations for Legionella growth.



What Causes Legionella to grow?

There are many variables that can cause it to grow inside of pipes and equipment, including fluctuations in pH levels, water temperature, stagnant zones, and insufficient levels of disinfectant. External factors such as water main breaks, construction in or around your building, or changes in municipal water supply can cause Legionella growth as well.

And where there's Legionella, there could be other waterborne pathogens present such as:

  • Pseudomonas
  • Acinetobacter
  • Burkholderia
  • Stenotrophomonas

While any building can be at risk for Legionella, certain facilities need to be especially vigilant:


Hospitals

Healthcare
Centers

Nursing Homes/Long-term Care Facilities

These types of facilities typically house more fragile populations, many with underlying conditions and compromised immune systems. Patients and residents in these facilities are at much higher risk when exposed to Legionella.

The presence of the Legionella bacteria in closed water systems can cause:

  • Legionnaires' disease, a severe form of pneumonia
  • Pontiac fever, a milder illness resembling the flu

It's important to have a clear understanding of the risks of Legionella, what causes it to grow, and how to prevent it. Check out our Legionella Resource Kit for more information.

Preventing Legionella and Waterborne Pathogens


The prevention of waterborne pathogens, including Legionella, requires a water safety management plan for your facility, and a team in place to get the work done and keep the plan on track.

While all water safety plans should be customized to the needs and challenges of individual facilities, most plans include these eight initial steps:

  1. 1.  Formation of a water safety team
  2. 2.  Creation of a water safety management plan and a Legionella prevention plan
  3. 3.  Taking water samples
  4. 4.  Monitoring of disinfectant levels
  5. 5.  Keeping hot water pipes at higher temperatures than Legionella can grow
  6. 6.  Frequent inspection of cooling towers
  7. 7.  Elimination of stagnant water
  8. 8.  Prevention of scale, slime and biofilm

Your operations staff may be able to handle some of these tasks, but it's a good idea to work with a water treatment partner with extensive experience preventing, mitigating and controlling waterborne pathogens. A water treatment expert can help you avoid commonly made mistakes, uncover areas of your facility that need closer monitoring, and keep you compliant with water safety standards for your industry.
