5 Strategies for Effective Legionella Control

28 August 2024

Ensuring the safety of your water supply is not just a legal obligation but also essential for the health and wellbeing of everyone who uses your facilities. Here we outlined five key strategies to help you manage and mitigate the risks associated with Legionella in water.



Comprehensive Legionella Risk Assessment


A thorough Legionella risk assessment is the cornerstone of any effective control strategy. This process involves identifying potential sources of Legionella bacteria within your water system, evaluating how bacteria can multiple, and pinpointing areas where people may be exposed. Our experienced team uses the latest techniques to conduct detailed risk assessments, providing you with a clear plan of action to minimise risks.


Regular Monitoring and Testing


Continuous monitoring and regular testing of water systems are crucial to maintaining control over Legionella bacteria. By frequently testing water samples for the presence of Legionella, you can quickly identify any emerging risks and take immediate action to address them. At Caledonian Heating & Plumbing Ltd, we offer comprehensive testing services to ensure your water systems remain safe and compliant with health and safety regulations.


Maintaining Optimal Water Temperatures


Legionella bacteria thrive in stagnant water and temperatures between 20-45°C. One of the most effective methods of control is to maintain water temperatures outside of this range. Hot water systems should be kept at a minimum of 60°C and cold water systems below 20°C. Our team can help you design and maintain your water heating and cooling systems to ensure they operate within these safe temperature ranges.


Implementing Regular Cleaning and Disinfection


Biofilms and sediment in water systems provide an ideal environment for Legionella growth. Regular cleaning and disinfection of your water tanks, pipes, and other system components are essential to control and prevent contamination. Caledonian Heating & Plumbing Ltd offers professional cleaning and disinfection services using industry-approved methods to ensure your water systems remain hygienic and safe.


System Design and Upgrades


The design of your water system plays a significant role in the control of Legionella bacteria. Systems with dead legs (sections of piping where water can stagnate) or those that are poorly maintained are more susceptible to bacterial growth. Upgrading and redesigning your water systems to eliminate these issues can significantly reduce the risk of Legionella contamination. Our expert team can evaluate your current system and recommend necessary upgrades or redesigns to improve safety and compliance.

When it comes to plumbing issues, timing is everything. A small leak can quickly turn into a major problem if left unchecked, while some situations demand immediate attention to prevent costly damage or business disruption. Understanding the difference between emergency and routine plumbing repairs can save you time, stress, and money, and help you know when it’s time to call in the experts. What Counts as a Plumbing Emergency? A plumbing emergency is any issue that poses an immediate risk to safety, property, or business operations. In commercial environments, even a short period of downtime can have serious consequences, so swift action is essential. Common plumbing issues include: Burst or leaking pipes – Sudden water leaks can cause flooding and damage walls, floors, and electrical systems. Blocked or overflowing drains - Particularly in high-traffic areas, this can create health hazards and disrupt operations. No hot water or heating - Especially critical in settings like schools, hospitals, or care facilities. In these situations, it’s vital to contact a qualified plumbing engineer right away. Our team at Caledonian Heating & Plumbing provides rapid-response emergency support to restore safety and minimise downtime for commercial clients. When Is It a Routine Repair? Routine plumbing repairs cover non-urgent maintenance tasks or issues that develop gradually. While they might not cause immediate disruption, they still need attention to prevent bigger problems later on. Examples of routine repairs include: Slow-draining sinks or toilets Minor leaks under basins or radiators Reduced water pressure Regular maintenance of heating systems or water tanks Scheduling routine repairs ensures your systems continue running efficiently and helps you plan maintenance at a time that suits your business, avoiding the cost and chaos of unexpected emergencies. The Benefits of Preventative Maintenance Many plumbing emergencies are avoidable with regular inspections and servicing. Planned maintenance helps identify potential issues before they escalate, ensuring your systems remain compliant, efficient, and reliable. At Caledonian Heating & Plumbing, we tailor maintenance schedules for each client, from small businesses to large facilities, to keep everything flowing smoothly year-round. Proactive maintenance also supports compliance with health and safety regulations, such as ACOP L8 for water systems and Gas Safe standards for heating installations.
