How to control Legionella – Part 2: the risks and the options…

Posted by Paul Limbrick on Aug 8, 2018 10:47:52 AM

As discussed in Part 1, temperature has limited effectiveness when treating biofilm bacteria (especially mature biofilm) but colonisation of a system with biofilm bacteria may (in the main) be avoided should water temperature be kept within specification and the water within the system kept in regular movement/turned over. Moreover, when outlets test positive for bacteria of ‘human importance’, it’s first of all important to question ‘why’ and to ascertain to what extent the water system has been compromised (ie, how big is the loss of control…?).

How to control Legionella - Part 1: the risks and the options…

Posted by Paul Limbrick on Jul 31, 2018 2:39:38 PM

Water undertakers have a responsibility to ensure that ‘wholesome’ water is delivered to the point of entry of buildings, this does not necessarily mean that such waters are free from microorganisms. Moreover, whilst drinking water should be free from parasites (cryptosporidium) and faecal contaminants (coliforms/E. coli), it’s common for wholesome water to contain aquatic bacteria, as such bacteria make-up the ‘normal’ microbiology of drinking water. Therefore, bacteria such as Pseudomonas and Legionella live preferentially in the environment and these soil-derived bacteria frequently reside within water supplied to buildings.
