Water Statutory Testing & Inspection

Legionnaires’ Disease is a water borne disease which causes a form of pneumonia. According to the HSE there are around 200-250 cases in the UK every year and 12% of them are fatal.

About half the cases are associated with foreign travel while many cases originating in the UK cannot be traced to their source. However, some outbreaks have been associated with cooling tower systems and hot and cold water systems in factories, hotels, hospitals and other establishments. Risk is increased by the presence of sludge or fouling.

Failure to comply may result inВ fines but in cases of serious neglect, prosecutions for involuntary manslaughter have been sought.

Water Risk Assessment

Water Risk Assessment

Under ACoP L8В a duty is placed on the ‘responsible person’ to carry out and regularly review a water risk assessment of their premises. A written record must be maintained and this now applies to all premises with a water system no matter how small.


The Assessment must include the following key steps ;

management responsibilities, including the name of competent person and a description of your system;

potential sources of risk;

any controls in place to control risks;

monitoring, inspection and maintenance procedures;

records of the monitoring results, inspections and checks carried out;

a review date.

The responsible person may conduct the assessment using standard advice documents or appoint a ‘competent person’ to carry out a professional risk assessment.

      (a) В checking the performance of the system and its component parts;В 

      (b) В inspecting the accessible parts of the system for damage and signs of
      contamination; andВ 

      (c) В monitoring to ensure that the treatment regime continues to control to theВ  required standard.

      According to the HSE routine in house monitoring should be conducted weekly – our water inspectors are happy to advise on the required procedures.
