Water Tank Cleaning & Disinfection for Stoke-on-Trent properties
Cold water storage tanks collect sediment, scale, debris and sometimes insects or vermin. That material feeds biofilm and gives legionella somewhere to grow. If an inspection finds contamination, the tank should be cleaned and disinfected. We carry out the work with minimal disruption and issue a certificate when it is done.
Cold water storage tanks in Stoke-on-Trent are often found in roof spaces and plant rooms of industrial units. Local water is moderately hard, which affects how quickly sediment and scale build up in tanks and how often cleaning is needed.
Stoke-on-Trent's former pottery works, industrial units, social housing and healthcare sites often carry legacy pipework from decades of building changes.

Legislation in England
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.
In Stoke-on-Trent, legionella law is enforced by Stoke-on-Trent 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. We cover all ST postcodes in and around Stoke-on-Trent.
