Water hygiene in Derby
Derby's engineering and manufacturing sites, university and healthcare estate include large, complex water systems and process water.
Large warehousing and student accommodation estates in the East Midlands often have long pipe runs and low-use outlets during holidays, both classic legionella risk factors.
Why local water matters
Water in Derby is generally moderately hard to hard. Hard water deposits limescale on shower heads, taps, TMVs and inside calorifiers. Scale gives legionella bacteria a protected surface to grow on and can stop thermostatic valves working properly, so descaling and servicing intervals should reflect it.
The rules that apply in Derby
Legionella and water hygiene. In England, legionella duties come from the Health and Safety at Work etc. Act 1974, the Management of Health and Safety at Work Regulations 1999 and COSHH 2002, with HSE's ACoP L8 and HSG274 setting the standard. Enforcement is by HSE or the local authority, depending on the premises.
Local enforcement. In Derby, legionella law is enforced by Derby City Council's environmental health team for offices, shops, hotels, restaurants and leisure premises, and by HSE for factories, warehouses, hospitals, schools and council-run premises.
