When do you need to carry out cleaning and disinfection?

The Health & Safety Executives guidance HSG 274 Part 2 says:


"2.126 The risk from exposure to legionella should be controlled by keeping the water system and water in it clean and free from nutrients, including those arising from contamination and corrosion; and maintaining its cleanliness. Hardness scale may also trap nutrients, encouraging biofilm formation and so form a barrier to disinfectants.


2.127 Where necessary, hot and cold water services should be cleaned, flushed and disinfected in the following situations, as specified in BS 8558"


  • on completion of a new water installation or refurbishment

  • on installation of new components

  • where the hot and cold water is not used for a prolonged periods

  • on routine inspection of the water storage tanks

  • if the system or part of it has been substantially altered or entered for maintenance purposes

  • following water sampling results

  • during, or following an outbreak or suspected outbreak of legionellosis linked to the system

  • or where indicated by the risk assessment
