ENQUIRE ABOUT THIS SERVICE
Prevent bacteria growth in your Cold Water Tanks

Cold water tank cleaning and disinfection is among the variety of services aimed at eliminating the risk of Legionella and a number of other bacteria growth in your property’s water systems. As legionella bacteria is prone to growing in stagnant water, it makes your cold water storage tanks one of the more likely places where harmful bacteria may appear. Water also can quickly become contaminated by a range of bacteria if cold water storage tanks are maintained poorly or irregularly. According to Legionnaires' Disease Technical Guidance HSG274 provided by Health & Safety Executive (HSE), cold water storage tanks require annual inspections, which would reveal if cleaning, disinfection, repair or even replacement is necessary.

As a result, keeping your cold water tank clean and properly maintained will remove the favourable conditions in which the bacteria can grow, including biofilm, sediment, corrosion or scale. It will also eliminate the risks of the rest of the water system getting infected due to a poorly maintained water tank.
