As many businesses are now closed due to the Covid-19 pandemic or are being used less frequently, we would like to remind you of the Legionella risks in unoccupied/less occupied properties where water can stagnate within water systems.
Water outlets on hot and cold water systems should be used at least once a week to help maintain a degree of water flow and to help prevent water stagnation.
You should consider implementing a suitable flushing regime to manage the risks or other measures such as draining the system if the business is to remain closed for a long period.
Guidance has been produced by European Society for Clinical Microbiology and Infectious Disease for managing Legionella in building water systems during the Covid-19 Pandemic.
