Water sampling and analysis is used to assay the level of bacterial infection before and after the water tank cleaning and disinfection process and to determine the success of the cleaning and disinfection undertaken. Once water sampling is complete, our Legionella Control Association (LCA) accredited technicians thoroughly scrub tanks to remove any biofilm or debris that has accumulated on the walls or floor. Residual dirt can reduce the power of the disinfectant – an effect called ‘sanitation load’.

Using LCA approved disinfectants such as chlorine, hydrogen peroxide and chlorine dioxide – our experienced water hygiene technicians thoroughly clean and disinfect the water tank before completing a second-round of sampling for:

• Legionella Pneumophila
• E.coli
• Total Coliforns
• Total Viable Count (TVC) – an overall view of any background contamination
• After water tank cleaning and disinfection, analysis of these counts should be zero.

As part of the Water tank cleaning and disinfection process, we also carry out thorough water tank defect assessments. The assessments are carried out in line with the requirements of HSE ACoP L8 and provide a detailed summary, and undertaking of any refurbishment required to bring the system up to acceptable standards as described in ACoP L8 where.

It all starts with maintaining your water tank. However, if this hasn’t been the case, we are here to help. We are able to locate anything that needs repairing and advise you on the next steps to ensure that your water tank is up to an excellent standard.
