Water Tank Cleaning & Disinfection for Belfast properties
Cold water storage tanks collect sediment, scale, debris and sometimes insects or vermin. That material feeds biofilm and gives legionella somewhere to grow. If an inspection finds contamination, the tank should be cleaned and disinfected. We carry out the work with minimal disruption and issue a certificate when it is done.
Cold water storage tanks in Belfast are often found in roof spaces and plant rooms of offices. Local water is mostly soft to moderately soft, which affects how quickly sediment and scale build up in tanks and how often cleaning is needed.
Belfast's mix of Victorian terraces, Titanic Quarter offices and apartments, hotels and healthcare sites are managed under Northern Ireland's health and safety framework, with HSENI as the enforcing authority for many workplaces.
