Why is water tank cleaning important for legionella control?
Ensuring the cleanliness of water tanks is essential for maintaining water hygiene standards. Here are three critical reasons why this practice is paramount:
-
Eliminating Breeding Grounds for Legionella: Water tanks can become breeding grounds for Legionella bacteria if not properly maintained. Accumulated silt, scale, and sediment in tanks provide nutrients for bacteria growth. Additionally, without proper screening, organic matter like leaves or small rodents can contaminate the tanks, further exacerbating the issue. Cold water storage tanks, often overlooked, may harbor these contaminants unseen.
-
Preventing Water Stagnation: Stagnant water fosters the growth of Legionella bacteria. Scale buildup can trap nutrients and form a biofilm, acting as a barrier to disinfectants. Regular draining and physical cleaning of water tanks help remove scale, sludge, and biofilm, thereby preventing bacterial proliferation.
-
Meeting Legal Requirements: Compliance with legal regulations regarding the inspection, cleaning, and disinfection of water tanks is mandatory. Maintaining thorough records of these activities demonstrates proactive measures to prevent diseases like Legionnaires’ disease.

Recently we carried out a clean and disinfection of a large cold water storage tank, below are photos of before and after the cleaning process. It is clear in figure 1 there was a high level of sediment visible in the water tank which needed to be removed to reduce the risk of legionella bacteria.
