Ice Machine Maintenance

Low water volumes combined with high temperatures and heavy bather loads make public hot tub operation challenging. The result can be low disinfectant levels that allow the growth and spread of a variety of germs (e.g., Pseudomonas & Legionella) that can cause skin and respiratory Recreational Water Illnesses (RWIs). Operators that focus on hot tub maintenance and operation to ensure continuous, high water quality are the first line of defense in preventing the spread of RWIs.

Hot tubs that are not properly operated and maintained can provide an ideal environment for spreading Legionella, the bacteria that causes Legionnaires’ disease and Pontiac fever. The phrase “hot tubs” in this document includes hot tubs, whirlpool spas, and hydrotherapy spas.

Preventing Recreational Water Illnesses (RWIs) is a multifaceted issue that requires participation from pool staff, swimmers, and health departments. Poor maintenance can result in low disinfectant levels that can allow the spread of a variety of germs that cause diarrhea as well as skin and respiratory RWIs. Although pool staff alone cannot completely stop these complex problems, they play a key role in assuring the health of pool visitors. By following a few simple steps, aquatic managers and staff can lead the way.
