Approved for 31 & 62 days and 3 & 4 months (extended life up).
In any public buildings, producting of hot water systems must undergo routine maintenance and monitoring to prevent or eliminate the appearance of biofilms or Legionella. To accomplish this, preventative and corrective procedures must be put in place (see below).
When routine (required) analyses indicate elevated levels of in Legionella sp. or Legionella pneumophilia (or other live aerobic micro-organisms), the responsible parties are alerted. The manager of the public building or the legal owner of the facility must then proceed to:
• conduct a more in-depth risk assessement analysis: confirm the level of contamination, identify the points of use involved, evaluate the vulnerability of the users, record the number of cases, etc.;
• protect users if the risk is judged to be significant (concentration of Legionella pneumophilia greater than 1000 CFU/L).
Installing anti-Legionella showerhead and tap filters is an effective and immediate response, among other corrective measures that are equally essential (see below). This ensures that the sanitary quality of water for users conforms to regulatory requirements. Protection using terminal filters is not intended for constant use but must be maintained as long as Legionella contamination remains above acceptable levels.
aqua-tools H&S sterilizing-grade filters have a fixed porosity of 0.1 µm, which guarantees complete elimination of all cellular micro-organisms (bacteria, yeast, molds, algae, etc.), including Legionella pneumophilia. The filters have been shown to be effective for up to 31 & 62 days and 3 & 4 months.

The principal preventative measures implemented in public buildings most often include:
• preventing stagnation in the water system by carefully managing the overall flow;
• fighting scaling and corrosion through improved system design and re-equilibration of water hardness;
• maintaining water at a high temperature (50°C) within the facility from the source until it is delivered to points of use. However, to prevent the risk of burns, the water should be mixed with cold water upstream of the points of use;
• monitoring the risk of contamination by monitoring different points throughout the system and by performing regular analyses to detect Legionella sp..
Experience shows that effective prevention must include monitoring of water quality. Routine tracking of the total biological burden by rapid microbiological analysis therefore provides numerous advantages. Learn more
Article 4 of the decree of February 1, 2010 specifies that “Legionella pneumophila counts must be less than 1000 CFU/L (colony-forming units per liter of water) at all at-risk points of use. When thresholds are not met, the manager of the facility shall immediately take the necessary corrective measures to reestablish the water quality in order to protect the users.” If the threshold is exceeded, the official must immediately:
• conduct a critical analysis of the contamination by performing new analyses at different points within the system to confirm the results and obtain more complete information (contaminated area, origin of contamination, cause of dysfunction, etc.);
• completely limit access to water usage points or protect users by installing sterilizing-grade filtration devices until analyses confirm the return to a normal situation;
• implement maintenance procedures, whether routine (purging, reestablishing water hardness or the amount of chlorine, etc.) or specialized (disinfecting the system via thermal and/or chemical shock). Complementary analyses must still be undertaken to confirm that the system has returned to normal.
Tracking the total biological load by rapid microbiological analysis is a reliable method for determining the origin of contamination in a system or evaluating the efficacy of a disinfection procedure. Learn more
