Legionella Control

Legionnaire's disease is 100% preventable. Protect your community and your business with a water management plan.

Water supply contamination is causing increased outbreaks of Legionnaire’s disease — a potentially life-threatening form of pneumonia. The Centers for Disease Control and Prevention (CDC) reports that between 8,000 and 18,000 people are hospitalized with the disease in the United States each year.

Legionella bacteria is found naturally in the environment, usually in warm water, making hot tubs, large plumbing systems, decorative fountains, hot water tanks and cooling towers common areas for risk. In addition, misting systems often found at grocery stores and parks, ice machines and humidifiers can become breeding grounds for the bacteria if not properly maintained.

In 2015, a combination of large outbreaks, standardization and regulation have thrust Legionella into the spotlight and put the water management practices of building owners and managers under a microscope.

Take action now.

Standard 188-2015 requires a Water Management Plan (WMP) for all buildings with a cooling tower and/or multiple other water systems where water mists may harbor Legionella. The WMP serves as a risk management plan that includes hazard analysis, risk mitigation and plan validation through testing and monitoring. If an outbreak occurs and you are not compliant with the standard, you can face more lawsuits, litigation, regulation, and loss of customers than you would if you were compliant, not to mention the detriment caused by Legionnaire’s disease.

Watertech can help you manage your risk for Legionella by providing tools you can use to develop, implement and validate a water management plan that is fully compliant with Standard 188-2015.
