Water Risk Management for Hotels & Casinos

Managing Legionella risk is a critical component of hotel and casino water system governance. The municipal water that enters a property is not sterile and can harbor Legionella bacteria, which can cause severe illness and even death if not properly managed. As the global leader in water risk management, Nalco Water helps hotel and casino operators implement structured programs to manage Legionella risk across complex, continuously operating hospitality environments.
