WHAT IS LEGIONELLA

Legionella Bacteria is naturally found in watercourses such as rivers, lochs, ponds and reservoirs but in low numbers. When this water is introduced into a man-made water system, the bacteria could proliferate rapidly. 

Legionella is dormant in temperatures below 20°C and multiplies in temperatures between 20°C and 45°C. Legionella cannot survive in temperatures above 60°C. Legionella enters your body through your respiratory system through vapours or droplets of water and has a 10% mortality rate. More information about Legionella and its effects can be found on the Health Protection Scotland Website.

 

OUR LEGIONELLA SERVICES

At pHX Water, we take the hassle away from water maintenance. You can depend on us for all the cleaning, sampling, and reporting services you need to meet water maintenance regulations and provide safe drinking water.

We can protect your customers, clients, and employees from harmful bacteria.

Legionella is a naturally occurring form of bacteria found in water sources such as rivers, lochs, ponds, and reservoirs. When water is pumped into your hot water tank or cold storage tank, legionella has a new breeding ground. If not properly managed, the non-hazardous amounts of legionella can rapidly multiply and pose a threat to health.

Legionella enters the body through the respiratory system via droplets of water. Even a small amount of legionella causes a 10% mortality rate.

Water systems are an often overlooked yet essential part of any commercial or industrial building. Without a water tank, your building would not be able to serve its purpose. It is important to regularly check the levels of bacteria in your water tank.

Our legionella risk assessment and water tank cleaning services identify and eliminate harmful levels of bacteria, biofilm, and debris in your tank.

 

Who Is at Risk of Legionella?

In Scotland, any building that has a private water supply must be subject to a legionella risk assessment.

Any water system that stores and/or recirculates water is at high risk of breeding excess amounts of legionella. Below are a few water vessels that should be considered for a regular legionella risk assessment.

  • Hot water tanks
  • Cold storage tanks
  • Hot tubs
  • Swimming pools

What Causes an Increase in Legionella?

Legionella is present in small amounts in natural water sources.

Once stored in your hot or cold water tank, legionella is at constant risk of breeding. Temperature is the most important factor when considering how to avoid excess amounts of legionella.

Here are a few important facts about legionella:

  • It is dormant in temperatures below 20°C
  • It cannot survive in temperatures above 60°C
  • It begins to breed between 20°C and 45°

In many cases, it is difficult to maintain a constant water tank temperature. This is why it is crucial to book an annual risk assessment.

WHO IS AT RISK OF LEGIONELLA?

Water systems that store or recirculate water are at a higher risk. These may include cold water storage tanks where poor hygienic conditions can provide a nutrient source for the bacteria or hot water vessels with non-conforming temperatures allowing the bacteria to multiply than be released into the system. 

This may also include recreational water systems such as hot tubs or swimming pools where stored water is at a temperature that would allow Legionella to multiply. This means that everyone in Scotland in is at risk of getting Legionella if a Legionella Risk Assessment isn’t completed by a competent person.

LEGIONELLA RISK ASSESSMENTS FOR LANDLORDS IN SCOTLAND

Landlords in Scotland must ensure a legionella risk assessment has been carried out to determine the level of risk of any of the water in the rental property becoming contaminated with Legionella. The Legionella risk assessment can be carried out by anyone competent to do so.

Most rented properties will be low risk, but it is a requirement for landlords to ensure that the risk of exposure to tenants and visitors by Legionella is properly assessed and controlled. This is a legal obligation and is enforced by the Health & Safety Executive (HSE).

Implementing simple, proportionate, and appropriate control measures will ensure the risk of contamination remains low. At PHX water our certified engineers will tailor a flexible action plan using a traffic light system to make it easy for you to understand and use as a working document. You will also receive a Legionella control scheme with every risk assessment that details what controls are required and at what frequency to ensure that your properties are compliant.

For most domestic hot and cold-water systems, the temperature is the most reliable way of ensuring the risk of exposure to Legionella bacteria is minimised i.e., keep the hot water hot, cold water cold and keep it moving. Our engineers will provide all this information to you in an easy-to-understand report and can assist with regular maintenance as part of your legionella risk assessment.

During our Legionella Risk Assessment, we will:

  1. Flush out the system prior to letting the property
  2. Identify and remove any debris getting into the system e.g ensuring the cold-water tanks, where fitted have a tight-fitting lid and remain uncontaminated
  3. We can set the control parameters to ensure water is stored at the correct temperature
  4. Identify and redundant pipework for removal

 

WHAT CAN A LANDLORD EXPECT A TENANT TO DO TO PREVENT LEGIONELLA?

  1. Inform the landlord if the hot water system is not heating properly
  2. Inform the landlord if the cold-water system is not running cold

The responsibility of the prevention of Legionella stays with the landlord and a regular legionella risk assessment is required to make sure they adhere to the law. Landlords should be aware that the risk of Legionella may increase if the property is unoccupied even for a short time For full details of legal responsibilities and control measures landlords should visit the HSE website.
