Three Counties Water were instructed by our client to manage their Healthcare Portfolio in North London and Essex to undertake Legionella Control Services for their properties. We carried out the Monthly visits covering around 8 Hospitals and primary care centres. In order to complete statutory water hygiene monitoring, as recommended in ACoP L8 Guidance and HTM04-01 Part B.

The Problem:

As part of our control checks we were to undertake 6 monthly Cold Water Storage Tank Inspection. During this inspection we identified internal hollow tank supports. Hollow supports should also no longer be used:
