As measures become more effective for controlling the spread of COVID-19, businesses and buildings will reopen at, what we hope is, a safe pace. When this happens, people will be returning to facilities that have been operationally shuttered for at least a month.
In anticipation of buildings reopening, the CDC recently released guidance. Upon re-opening, much of the focus will be on the known measures for preventing the spread of the COVID-19 virus. However, a commonly over-looked hazard is the safety of the building’s water supply and maintenance of the various water systems.
In occupied facilities, water flow is relatively constant and consistent. When water does not flow within a water system, it becomes stagnant and grows bacteria. Further, any disinfectant (e.g. Chlorine) added to the water by the public water source, has likely dissipated.
Of particular concern is a pathogenic, water-borne bacteria known as Legionella Pneumophila. While this bacterium is common to the environment, when introduced into a building’s water systems, it presents a potential hazard. Essentially, by inhaling/aspirating water containing certain strains of this bacteria, humans contract the potentially fatal Legionnaires Disease (LD). Sources of infection are often devices that aerosolize water. These include:
The good news is that LD is controllable and not contagious. The best prevention is to control the growth of this bacteria in water systems and to reduce the likelihood of inhaling the water, especially among the immuno-compromised population. Here are some measures recommended by the CDC
