Understanding why Cold Water Storage Tanks require periodic maintenance and how this process supports efficient Legionella control, is vital for the effective management of any water system.

In order to minimize the risk of waterborne bacteria in any water system, water storage tanks should be inspected and cleaned on a regular basis.

Why? Over time, water storage tanks are susceptible to contamination of debris and sediment build up, affecting the quality of the water supply. Microbial organisms feed off fouling in a tank and so the risk of multiplication of bacteria is high within poorly maintained systems.

The growth of microbes in a water tank allows formation of slime. The microbial biofilm slime acts as a barrier allowing the growth of harmful bacteria making it difficult to remove. Storage tanks are therefore required to be flushed with disinfecting chemicals to remove any build-up of biofilm and to prevent stagnation of water.

The Enviroliance team are experienced in carrying out tank inspections across commercial, public health and regulatory sectors.

As part of this process, we advise when Tank Cleaning and Disinfection is required to maintain Legionella control, where our fully trained engineers will conduct a full tank inspection to determine the quality of water supply from the source. If a clean and disinfection is required after inspection, Enviroliance will conduct a full drain, clean and disinfection of the tank following the guidelines outlined in ACoP L8.

Upon completion, you will receive a document of certification to acknowledge the cleaning and disinfection of the tank, and thereafter our experienced technicians will offer our monitoring and maintenance service to ensure frequent inspection, significantly reducing the risk of any future contamination.
