Water Treatments / Chemical Cleaning
We all know that we need water to survive, but consider what procedures it must go through to be safe for human consumption and use. For example it is vital that cold water storage temperatures are kept below 20°C. It is also necessary to keep stored hot water (HWS) at a temperature of 60°C or above. This then reduces the possibility of bacterial problems occurring. However, it is not as simple as setting temperatures and leaving it at that.
To comply with legal duties, employer’s and those with responsibilities for the control of premises should follow the guidance in the Approved Code of Practice L8 “Legionnaires’ Disease: The control of legionella bacteria in water systems.” Good practice requires that regular inspection and monitoring is carried out and findings recorded to ensure that equipment is maintaining temperatures and operating correctly. Buildings can be complex and pipework configurations within them can be complicated, they can also change over years with refurbishments and extensions, making some pipes redundant but left still attached to the system. If water in these redundant pipes becomes stagnant, flushing will probably not be enough to eliminate baterial risk and therefore it is crucial that these “dead legs” are removed from the system.

Quotation: “Legionnaires Disease is a potentially fatal form of pneumonia which can affect anybody, but which principally affects those who are susceptible because of age, illness, immunosuppression, smoking etc”. www.hse.gov.uk
Quotation: “It is caused by the bacterium Legionella pneumophila and related bacteria that can be found naturally in environmental water sources such as rivers, lakes and reservoirs, usually in low numbers. As they are commonly found in environmental sources they may also be found in purpose built water systems such as cooling towers, evaporative condensers and whirlpool spas”. www.hse.gov.uk
Quotation: “The agent that causes Legionnaires’ disease is a bacterium called Legionella pneumophilia. People catch Legionnaires’ disease by inhaling small droplets of water suspended in the air, which contain the bacteria”. www.hse.gov.uk
