The Importance of Annual Cold-Water Storage Tank Inspections

Annual inspections of cold-water storage tanks are not just a regulatory requirement but also a crucial aspect of maintaining water hygiene standards within your establishment. These inspections are vital to ensure both the structural integrity of the tank and the quality of the water it holds, particularly during warmer months when temperature control becomes paramount.

To adhere to these regulations, it is imperative to enlist the expertise of a trained Water Hygiene Technician. These technicians are equipped to thoroughly inspect the cold water storage tank, meticulously documenting its condition in the monitoring log book. Should any discrepancies be found, they follow established protocols, escalating issues as per the chain of command outlined in the control scheme, and executing remedial actions promptly to ensure the tank’s continued functionality within appropriate timelines.

During the inspection process, both the interior and exterior of the tank are inspected, along with the quality of the water it contains. Key points of assessment include ensuring a tightly fitting and undamaged lid, the presence of insect and vermin screens on overflow and warning pipes, proper lagging to maintain water temperature, absence of biofilm or stagnation signs on the water surface, and correct positioning of inlet and outlet to prevent stagnation.
