Cold water tank cleaning and disinfection is among a variety of services designed to eliminate the risk of legionella and a variety of other bacteria growth in water supplies in your house. Since legionella species are prone to grow in stagnant water, it makes the cold water storage tanks one of the places where bad bacteria can grow.
Water can also quickly become contaminated by a range of bacteria if the tanks for cold water storage are improperly or irregularly cleaned.
According to the Legionnaires' Disease Technical Guidelines HSG274 issued by the Health & Safety Executive (HSE), cold water storage tanks are subject to regular reviews, which will indicate whether cleaning, decontamination, improvement, or even replacement is required
Over time, cold water tanks, usually located in condos, basements, and airing cabinets, become polluted with waste, algae, scale, sludge, biofilm, fouling, wall molding, stagnation, corrosion & rust, foreign bodies, and plant formation.
If contaminants reach or build up in our water supplies over time, they offer an environment for bacteria such as Legionella bacteria and E.coli to develop.
When and how often you should clean it depends a lot on whether the cold water storage tanks are potable or non-potable. Potable water storage tanks need to be maintained more frequently when they are used to provide drinking water for people.
At the end of the day, domestic water tank cleaning is all about keeping proper water hygiene, human health and safe water supply systems.
Due to age, cracking, damage, or rust, a fresh water tank installation is needed, and trying to fix such a water tank is something that even the most skilled DIY specialist should not attempt because it can be a long and expensive process.
You should only authorize the cleaning, servicing, and substitution of your cold water storage tank to experts.
