          How Often Should You Clean Your Water Tank? Expert Advice


To ensure the safety and cleanliness of your cold water storage tank, it is recommended to have it inspected and cleaned on an annual basis. However, the frequency may vary depending on the results of a site-specific legionella risk assessment. It is important to also keep an eye out for visible signs of sediment, stagnant water, biofilm, corrosion and flora growth during routine inspections, as this may indicate the need for a cleaning and chlorination.

The Importance of Cleaning Cold Water Tanks

Regular cleaning of cold water tanks is essential for maintaining water quality and safeguarding public health. Over time, sediment, debris, and microbial growth can accumulate in these tanks, compromising the cleanliness and safety of the stored water. Cleaning interventions are vital to prevent contamination and ensure that the water remains safe for consumption.

Understanding the Cleaning Process

Cleaning a cold water tank involves several key steps to effectively remove accumulated contaminants and restore water quality:

  • Draining the Tank: The first step is to drain the tank completely to allow access for cleaning and inspection.
  • Removing Sediment and Debris: Sediment and debris at the bottom of the tank are manually removed using appropriate tools.
  • Scrubbing and Disinfection: The interior surfaces of the tank are scrubbed thoroughly to remove biofilm and microbial growth. Disinfection is then carried out using approved chemicals to eliminate any remaining bacteria or pathogens.
  • Rinsing and Refilling: After cleaning and disinfection, the tank is rinsed with clean water to remove any residual cleaning agents. It is then refilled with fresh water from a clean source.

Frequency of Water Tank Cleaning

The frequency of cleaning cold water tanks depends on various factors, including water usage, tank size, and environmental conditions. As a general guideline, tanks should be cleaned at least annually. However, in high-demand environments or areas with poor water quality, more frequent cleaning may be necessary to ensure continuous water safety.

Benefits of Regular Water Tank Cleaning

Regular cleaning of cold water tanks offers numerous benefits, including:

  • Improved Water Quality: Cleaning removes contaminants, ensuring that the water remains clean and safe for consumption.
  • Prevention of Health Risks: By eliminating microbial growth and pathogens, cleaning reduces the risk of waterborne illnesses.
  • Extended Lifespan of Equipment: Proper maintenance through regular cleaning can prolong the lifespan of cold water tanks, reducing the need for premature replacement.
