Legionella Prevention In Hotels, Resorts & Cruise Lines

Legionella Prevention and Remediation in the Hospitality Industry

Whether you’re managing a luxury hotel, resort, or cruise line, your water systems can be at risk for Legionella exposure, creating a potential safety issue for guests, employees or other visitors to your facility. Mitigating this risk and the risk of other waterborne pathogens by being proactive is a critical step. Cooling towers, spas, pools, and plumbing networks all require vigilant oversight to prevent Legionella bacteria, which can cause Legionnaire’s disease when people inhale or aspirate tiny water droplets containing the bacteria. 

Should any Legionella be detected, IWC Innovations springs into immediate action with our emergency remediation services, dealing with the situation quickly, expertly, effectively, and thoroughly, away from the public eye.  As your partner, IWC Innovations will empower your facility managers to stay ahead of waterborne risks, protecting your guests and your reputation.

Ice machines can harbor Legionella bacteria when heat from compressors or nearby warm areas raises water temperatures inside the unit, creating conditions ideal for bacterial growth. The bacteria can survive freezing and cause infection when contaminated ice melts or is aspirated.
