About the event

The global hospitality sector is expanding at a fast pace to keep up with the booming travel & tourism business. Improvements in the hotel sector infrastructure is typically done by the provision of superior amenities as a value proposition to the guests, which include water features such as spas, lobby fountains, splash pools in guest rooms etc. These water sources and supply lines running into and within the building provide locations for the growth of legionella bacteria and pathways for potential exposure to infection and contraction of legionnaires disease. In addition, hotels with modern HVAC systems which utilize high-efficiency water cooled chillers connected to cooling towers requiring high standards of water hygiene to be maintained in the circulating water, which otherwise could emanate contaminated drifts (aerosols) – one of the main causes for the proliferation of legionella bacteria.

The presentation deals with legionella control in the hospitality sector and traces the origins, proliferation, and monitoring of legionella bacteria and the causes and symptoms of legionnaires disease. Various risk systems are discussed with emphasis on cooling towers as high-risk systems. The concept of a biofilm as the culprit within pipelines is explained. Basics of monitoring the legionella bacteria, various global standards with a specific reference to ANSI-ASHRAE standard 188-2018 and its importance are highlighted. The presentation touches upon solutions to legionella control in hotel water systems with a reference to various water treatment strategies being practiced. The presentation concludes with the emphasis on legionella compliance as the way forward for the global hospitality majors to protect their brand image and ensure continuity of business.
