If you fail to correctly maintain water tanks within a building, they are extremely high-risk areas for the spread of disease.

Water Storage Tanks

Cleaning and disinfection of water storage tanks is one of the key factors to ensuring there is a clean water supply to the outlets it serves, without regular cleaning, a build-up of dirt and sediment can be present in the tank. There are numerous types of bacteria that can be present in water, including the potentially fatal legionella. If you fail to correctly maintain water tanks within a building, they are extremely high-risk areas for the spread of disease. Clean and disinfection services are carried out in accordance with ACoP L8 following the procedures outlined in BS8558, and a certificate is issued upon completion of the works, as well as a full report showing pre and post pictures of the clean. A clean should take place:

  • If a routine inspection shows it to be necessary e.g sediment and dirt build up.
  • If the system or part of it has been substantially altered or entered for maintenance or remedial purposes in a manner that may lead to contamination, or
  • During or following an outbreak or suspected outbreak of Legionellosis
Our Service

We start with an initial assessment to identify any health and safety precautions. Then once we have secured a safe working environment, we can begin isolating the cold-water storage tank and pump sets to cease any flow of water. Once isolated, we can then begin to drain the tank and remove any sediment or dirt which may have harvested in the tank, which is then pursued by a chemical clean using predominantly silver based hydrogen peroxide however chlorine may also be used depending on the condition.

Once the clean has been complete and the tank has been flushed through with clean water, samples are taken to test for TVC, e-coli, coliform and Legionella by a UKAS accredited laboratory. Once the entire disinfection process has been completed, the tanks have been refilled and the tests have returned all clear, we are finally able to issue of disinfection certificate and sample results for your logbook.
