[Does automatized disinfection of traps by chlorine reduce water related contamination?]

Sanitary U bends are very contaminated places from a microbiological point of view. They may even be dangerous for immunocompromised patients. Although daily chloride disinfection of U-bends is ineffective, it seems to work when performed after each use of sanitary devices. On line disinfection reduces not only U-bend bacteriological contamination but also all surrounding surfaces.
