Our experience with the hotel and resort industries

Since 1983 Dr. Richard Miller had been providing his expertise in Legionnaires’ Disease (LD) and Legionella detection to the hotel and resort industry.   By providing sampling, analyses and recommendations for whirlpool spas, potable water, decorative fountains and cooling towers systems he was able to assist in providing safe environments with a reduced risk for Legionnaires Disease at these facilities.  EST has continued to lead the way in Legionella for the hotel and resort industry by constantly innovating and redefining its approach to fit the unique challenges of the industry. 

Dr. Miller sat as a voting member of American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) Standard 188.  This standard was developed as “code ready” language to provide guidance to building owners and operators to develop Water Management Plans (WMP) to reduce the risk of a LD outbreak in their facilities.  On June 26, 2015, the American National Standards Institute (ANSI) approved ASHRAE Standard 188.  This newly approved ANSI/ASHRAE Standard 188-2015 sets forth a plan for the risk management of Legionella in building water systems.  The standard undergoes continuous maintenance and is reviewed every three years.  The latest revised edition is ANSI/ASHRAE 188-2021. 

Many hospitality buildings fit the requirements for compliance with ANSI/ASHRAE 188-2021.  This would include having the following water systems onsite, Cooling Towers, Whirlpool Spas, Ornamental Fountains or Misters.  Another requirement is any building over 10 stories with a centralized potable water system. Once a building is determined to meet these conditions it is required for the owner or operator to develop a WMP to limit the risk of Legionnaires Disease that may be sourced from their building.  EST can help you understand these requirements and assist with the development of your WMP. 

As the hotel and resort industry moves to more comprehensive WMP and great competition, we have moved to increase our services to provide them with even faster and more reliable results.  The introduction of our Viable Legionella vPCR sampling can provide answers in as little as four hours from the time that the samples are received in the laboratory.  This critical speed can provide you the confidence that your water systems are not at risk for a LD outbreak or get your facility back up and running quickly and safely in the event that a disinfection of a water system is needed (e.g. a whirlpool spa).  Click the button below to learn more about Viable Legionella vPCR.

COVID-19 and Legionella

The impact COVID-19 has had on everyone extends to building water systems, both cooling towers, and potable water systems. Inactivity and limited use can contribute to the formation of biofilm allowing for Legionella proliferation. EST can assist in developing a reopening plan for your facility, including highly effective re-commissioning disinfection procedures and follow-up validation testing.
