Col,

Regarding the sampling you undertook during your time with a local authority. Was the work published, or do you still have a copy of the results etc.?

I recently completed an MSc in Occupational Safety and Health where my research and dissertation was undertaken with regards to environmental sampling for legionella bacteria within domestic water systems. I am considering embarking on a PhD, which would again involve legionella in some way, and would be interested in reading the results of your work.

I gather you are obviously very interested in legionella and would in turn be happy to supply you with a .pdf file of my dissertation.

Regards

Giles Davis

I thought I would ask the institute of plumbers this is what they said :

Dear Mr Pope



Please find below, my response to the discussion regarding the above, could you please post it on my behalf.
Regards,
Danny

The contractor concerned has a duty of care upon identifying an installation that does not meet the requirements of the Water Regulations; to advise that these cisterns should be de-commissioned and replaced with cisterns that conform with the requirements of the 1999 Water Supply (Water Fittings) Regulations.
The Water Regulations Guide states that:

“Cisterns storing water for domestic purposes should be watertight and, where required, be lined or coated with a suitable impermeable material; they shall be provided with warning and overflow connections, as appropriate, which are so constructed and arranged as to exclude insects. They should have a rigid, close fitting and securely fixed cover which is not airtight but which excludes light and insects from the cistern; be made of materials which do not shatter or fragment when broken and which will not contaminate any water which condenses on its underside; and, in the case of a cistern storing more than 1000 litres of water, be constructed so that the cistern may be inspected and cleansed without having to be wholly uncovered.”


By informing you that these cisterns should be replaced, the contractor concerned is exercising his/her duty of care, as he/she has identified a situation/situations where a cistern does not comply with the current Water Regulations, and it would not be possible to upgrade it to meet these requirements, therefore the cistern should be replaced one that meets the requirements of the current Water Regulations.
Advice should be sought from the HSE regarding the removal and disposal of the current cisterns.

The Water Supply (Water Fittings) Regulations 1999 are not retrospective and you do not have to do anything to upgrade the system until it is worked upon.
