Legionella Risk Assessment

As a house owner, you may have to get a legionella risk assessment carried out. Legionella is a dangerous bacterium that can cause Legionnaires’ disease and Pontiac Fever. While the latter is a mild illness, the former can prove to be fatal in certain cases. The most high-profile case of Legionnaires’ disease was back in 1976, when more than 29 people were killed. You can’t carry out a risk assessment on your own. Instead, you will have to hire a professional water treatment company to do the job for you. Ideally, it is beneficial to get your tank inspected and the water content. However, if you don’t have enough money to hire a water treatment company, here are a few ways that you can carry out the risk assessment yourself:

Legionella Risk Assessment

Identify the Sources of Risk

The first step is to identify the sources of risk. Here are a few things that you should check:

  • The water is stored at a temperature between 20 and 45 degrees Celsius;
  • The water is exposed to nutrient sources such as biofilms, organic matter, sludge or rust;
  • The conditions where the water is stored encourage the multiplication of bacteria.

Eliminate the Risks

Once you have identified the risks, the next step is to manage responsibilities. While you can eliminate these risks on your own, there are many other factors that can promote the growth of legionella in the water supply. That is why you should seriously consider hiring a professional water treatment company. A professional company will use powerful equipment in order to carry out a full risk assessment.

Apart from using computer aided design technology in order to create three-dimensional models of your water systems, the company will also carry out a thorough assessment of all assets on site. This will give you an idea of all the assets that fail the guidelines. The company will also check whether the water storage tank and the supply lines are hygienic and comply with the guidelines mentioned in the Water Regulations Act of 1999.

The company will also give you a detailed summary of all remedial actions that can be carried out in order to limit the risks of legionella. In case you want on-going monitoring services, the company will also create a dedicated schedule to help with such services.

Getting a risk assessment carried out is an excellent way to ensure a healthy supply of water. Ideally, you should consider getting your water tank and supply checked once a year. However, if the risk of legionella is higher, you may have to consider setting up a monitoring schedule.

Make sure you hire a professional, certified water treatment company. In the UK, there are many companies that offer water treatment services. Most of these companies have websites that you can visit. You can easily check out their services online and contact them for a thorough assessment. You can also negotiate the rates with the company if you use more than one of their services.
