Is your water tank compliant?

All cold water storage tanks are required to be internally and externally inspected annually at an absolute minimum to ensure compliance with ACoP L8.

Legionella control engineers or trained in house staff must assess the general condition of cold water storage tanks to ensure they have an adequate turnover of water and no biofilm is present on the water’s surface.

They must also check that there is no build up of sediment on the base of the water tank which has the potential to harbour harmful bacteria such as Legionella.

Routine TVC (total viable count) and Legionella sampling of your sites cold water tanks carried out by Legionella control engineers also help to ensure your sites cold water storage tanks are free from harmful bacteria such as Legionella, E.coli & Pseudomonas.

Annual water tank cleaning is not a legal requirement, however annual water tank inspections are, therefore if any of the issues above are apparent a water tank clean and disinfection is recommended to be carried out.
