Hospital-Acquired Infections (HAIs) are often caused by water distribution systems in hospitals that fail to minimize the presence of bacteria, fungi and protozoa. Also, pathogens from tap water will further put hospital patients at risk by contaminating soaps, cleaning and antiseptic solutions.
Patients within health facilities are most susceptible to infections due to open wounds, invasive devices and/or compromised immune systems. To reduce the risk of infections from tap water, many hospitals have chosen to provide additional disinfection of their water supply at the point of entry.
It is particularly important to properly disinfect / decontaminate newly installed plumbing, because plumbers do not work under sterile conditions, and neither are pipes and fixtures supplied in sterile packing. A proper initial disinfection has a lasting effect. This is the work Osorno did, for example, at the Alberta Children's Hospital; after 10 years, there is still no re-contamination.
