Legionella Prevention

Legionella prevention 

At Richmond Hydrochem Special Projects, we have extensive experience in handling Legionella prevention tests and risk assessments.

You can rely on our expertise

Our business works with many companies like yourselves whether you are in the public or private sector, a business owner or a person responsible for Legionella compliance. Understanding that Legionella prevention is probably only one area of the health and safety responsibilities you manage, we aim to keep our services as straightforward and practical as possible, meeting the requirements of health and safety legislation. Our services are intended to keep the risk of Legionella to a minimum and to control bacteria in order to protect you, your staff and anyone who comes into contact with the water in your building.


In our first meeting, we would need to establish your requirements as it is important to ensure that a current risk assessment has been carried out. You will also require a maintenance plan to keep risks to a minimum, this is developed from the findings of the risk assessment, examples of this can be a tank clean and chlorination carried out annually. A Log book would be provided where all records are kept such as the responsible person being documented and monthly temperatures reported from various taps. Temperature recording is important as this ensures Legionella cannot multiply in their desirable temperature range of 20◦C to 45◦C. These records must be kept for five years should an inspector ask to see them.

The reason we protect against Legionella is due to the fact that it is a potentially fatal form of pneumonia caused by exposure to bacteria. It can affect anyone, however certain people can be more at risk, for example those over 45 years, smokers or those with impaired immune systems. The risks you potentially hold are based in your hot and cold water system. Obviously these systems are all different in design and age, therefore an initial Legionella risk assessment is important to determine the risks from your particular system.

Mentioned below are our relevant services for businesses such as care homes, educational premises, hotels, hospitals, factories, warehouses, offices and many more types of properties. 
Water treatments

Some of the reasons why you should be concerned

Examples of potential risks from your water system include possible dead legs where water is collecting and stagnating; water storage tanks without lids or no cleaning maintenance regime and water temperatures at a level in which bacteria may multiply. These issues are all straightforward to eliminate with the correct assessment. To comply with the law you must have identified and assessed potential sources of exposure. You must then introduce a plan of action to control any recognised risk. If there is an out outbreak of Legionella and nothing is in place you could find yourself liable, if you are the responsible person.
