Cleaning & Disinfection Services

Do you have forgotton cold water storage tanks hidden in your roof space?

Are they 'out of site, out of mind?' or are they regulary inspected, cleaned and disinfected?


You’ll be surprised at the horrors we discover in some cold-water storage tanks.


You see, because the mains supplies your cold water, in time your tank will inevitably accumulate debris, sludge and silt. It makes the water look dirty.


What’s more, it’s not uncommon to discover contamination from pigeon poo or even dead, decomposing rodents floating about. It doesn’t bear thinking about right?


Would you drink this water?




It means regular cleaning and disinfection of your cold-water storage facilities are a smart preventative measure to ensure:

  • Your water supply is clean, hygienic and free from visible contaminants

  • Your tank is properly managed to reduce the risk of exposure to legionella bacteria

  • Your tank and its cover are fit for purpose and free from the need for refurbishment or replacement.
