The Legionella Policy can be viewed here


Legionella is the name given to a group of bacteria which occur in almost all fresh water, including in all likelihood from time to time, the mains. They are also found in streams, rivers and lakes, in soil and in compost. The name comes from an outbreak of pneumonia affecting delegates at a conference of the American Legion in 1976.

Generally, legionella are not a direct problem as they occur in low concentrations in water and do no harm; it is quite safe for normally healthy people to drink water containing legionella although anyone with a serious medical condition does run a risk of infection. The danger only arises if the numbers increase significantly in warm water is inhaled in fine droplets such as is produced by showers and to a lesser extent taps, ballcocks etc.

The University works to the principles of control and management identified in the Health and Safety Executive (HSE) Approved Code of Practice and Guidance document “The Control of Legionella Bacteria in Water Systems” (ACOP L8), a copy of which is kept by the Estates & Facilities Management.

The University has its own Water/Compliance Manager within Estates and Facilities Management. Tel: 0114 222 9116
