Water tanks can be cleaned by someone who is competent and trained to do so. Careful consideration should be taken with tanks that supply drinking water as this procedure carried out incorrectly could result in contamination to the water supply. Some water tanks are deemed to be a confined space and specialist training / equipment is required to ascertain the risk and implement a safe system of work. Once a tank has been entered or touched with any requirement it should be disinfected as per BS EN 806-5:2012, BS 8558:2015 and BS PD 855468:2015.
