Water Tank Cleaning & Disinfection
Water tank cleaning and disinfection is necessary for water hygiene, no matter what size water tank you own, it is essential to keep on top of the cleaning and disinfection of the tank.
Mains water can contain low levels of bacteria and dirt (acting as nutrient) which can accumulate in water storage tanks and cisterns. If left unchecked this can flow through to contaminate the entire system. Water sampling and analysis can be used to assay the level of bacterial infection before and after the water tank cleaning and disinfection process.
Regular inspection (including water sampling and analysis) of water tanks, especially those for potable water, is essential Water tank cleaning and disinfection, often referred to as tank chlorination, recommended annually.
Cleaning Water Tanks To Government Standards
Working to BS:8558 – 2015 and the ACoP L8, HSG274 – Ara Environmental Ltd sample, analyse, clean and disinfect storage tanks and pipework throughout the building. Particularly stubborn contamination in the form of biofilms within pipework might require more aggressive disinfection using chlorine dioxide.
Water tank cleaning and disinfection is most effective after it has been scrubbed clean to remove biofilm from the sides and debris from the floor. Any residual dirt can reduce the power of the disinfectant – an effect called the sanitation ‘load’.
As part of the Water tank cleaning and disinfection process we will examine the tank/cistern to the requirements of ACoP L8, HSG 274 and report any defects. We can then undertake the tank refurbishment or repair to bring up to current standards as described in the ACoP L8 and HSG 274.
Water Tank Cleaning, Disinfection and Chlorination
Once the Water tank cleaning and disinfection and chlorination process to BS:8558 – 2015, has been completed, the results can be assessed. This is usually done through water sampling and analysis for various bacteria in particular:-
- Legionella pneumophilla
- Total coliforns
- Total Viable Count (TVC) which gives and overall view of any background contamination
After water tank cleaning and disinfection, analysis of these counts should be zero.
