Why Water Tank Safety Matters
Water tanks supply us with water for drinking, cooking, cleaning, and more. But when neglected, these essential systems can become breeding grounds for harmful bacteria, particularly Legionella. This bacterium thrives in temperatures between 20-45°C and can cause severe respiratory illnesses, including the potentially fatal Legionnaires’ disease.
Key Risk Factors in Water Tanks:
- Stagnant water: Idle water provides an ideal environment for bacterial growth
- Sediment build-up: Accumulation of debris offers nutrients for bacteria
- Ideal temperature range: Legionella flourishes between 20-45°C
- Poor maintenance: Neglected systems are more susceptible to contamination
- Scale formation: Provides a surface for bacteria to adhere and multiply
- Biofilm development: Creates a protective layer for harmful microorganisms
Legal Requirements: Staying Compliant in the UK
In the United Kingdom, building owners and managers have a legal duty to manage Legionella risks. This isn’t just bureaucratic red tape – it’s a crucial measure to protect public health. Key compliance requirements include:
- Annual water tank inspections: Regular checks to ensure system integrity
- Risk assessments by qualified professionals: Identifying and mitigating potential hazards
- Adherence to HSE guidelines: Following HSG274 and ACOP L8 recommendations
- Maintaining accurate records: Documenting all inspections, assessments, and treatments
- Employee training: Ensuring staff understand the risks and proper management procedures
Ignoring these requirements is potentially dangerous and could lead to severe consequences, including fines, legal action, and most importantly, putting people’s health at risk.

Temperature Control: Your First Line of Defence
Proper temperature management is crucial in preventing Legionella growth:
Cold water
Store and distribute below 20°C to inhibit bacterial proliferation
Hot water
Store at 60°C or higher and distribute at 50°C+ to kill bacteria
Regular checks
Monitor temperatures monthly at sentinel outlets
Temperature differentials
Ensure hot water reaches outlets within one minute
Thermal disinfection
Consider periodic high-temperature flushes for added protection
Maintenance: The Key to Safe Water
Regular maintenance isn’t just good practice—it’s essential for safety and compliance:
- Regular maintenance isn't just good practice—it's essential for safety and compliance:
- Clean and disinfect systems regularly: Remove biofilm and sediment
- Remove dead legs in pipework: Eliminate areas where water can stagnate
- Flush rarely-used outlets weekly: Prevent water from becoming stagnant
- Clean showerheads quarterly: Remove scale and biofilm build-up
- Insulate pipework: Maintain correct temperatures throughout the system
- Replace worn components: Ensure all parts of the system function correctly
Testing and Monitoring: Stay Vigilant
Constant vigilance is crucial in maintaining safe water systems – that means legionella testing, and legionella monitoring:
- Conduct periodic water sampling: Test for Legionella and other harmful bacteria
- Check hot water cylinder temperatures monthly: Ensure they remain above 60°C
- Inspect cold water tank temperatures bi-annually: Verify they stay below 20°C
- Monitor water quality parameters: Check pH, chlorine levels, and total dissolved solids
- Implement a Legionella control scheme: Develop and follow a comprehensive management plan
- Use accredited laboratories: Ensure accurate and reliable test results
Additional Control Methods for Legionella and Water Tanks
While temperature control and maintenance are primary defences, consider these additional measures:
- Copper and silver ionisation –Effective long-term solution for controlling Legionella.
- UV disinfection – Kills bacteria as water passes through the system.
- Chlorine dioxide treatment – Provides residual protection throughout the system.
- Point-of-use filters – Offer an extra barrier against bacteria at high-risk outlets.
Cost Considerations and Benefits
While the thought of unexpected disinfection costs may be daunting, delaying the process can lead to more significant expenses in the long run. Factors influencing the cost include the complexity of the disinfection, required chemicals, accessibility, and the overall scale.
However, investing in thorough disinfection is an investment in health, safety, and long-term cost savings. Get in contact with our team at PTS for a more direct quote – allow us to answer any questions you may have.

Legionella and Water Tanks - FAQs
How often should I have my water tanks inspected in the UK?
Annual inspections are legally required under UK regulations. However, more frequent checks may be necessary depending on your system’s risk level and complexity. Get in touch with us, and we’ll guide you through the process of an inspections. It’s simple, cost-effective, and we at PTS, operate nationwide.
What are the early symptoms of Legionnaires' disease?
Early symptoms often resemble severe flu, including high fever (above 40°C), muscle aches, and dry cough. As the disease progresses, shortness of breath, chest pains, and gastrointestinal symptoms may occur.
Can Legionella affect cold water systems in the UK climate?
Yes, while Legionella thrives in warm water, it can survive in cold water systems, especially during warmer months. It may multiply when temperatures rise or in areas where cold water pipes are close to heat sources.
How long does a typical water tank cleaning process take for a commercial building?
The duration varies, but most cleanings take 1-2 days, depending on the tank size, condition, and accessibility. Larger or more complex systems may require additional time.
Are there any natural methods to prevent Legionella growth in water tanks?
While professional treatments are most effective, some natural methods can help. Regular flushing, maintaining proper temperatures, and ensuring good water flow can create less favourable conditions for Legionella growth.
What's the difference between a Legionella risk assessment and a water tank inspection?
A Legionella risk assessment evaluates the entire water system for potential Legionella risks, including tanks, pipework, and outlets. A water tank inspection focuses specifically on the condition, cleanliness, and functionality of water storage tanks.
How quickly can Legionella colonise a water system in ideal conditions?
Under ideal conditions (stagnant water at 20-45°C), Legionella can colonise a system in as little as 2-10 days. This rapid growth emphasises the importance of regular monitoring and maintenance.
What are the legal consequences of non-compliance with water safety regulations in the UK?
Non-compliance can result in substantial fines, legal action, and potential criminal charges under the Health and Safety at Work Act. In severe cases involving fatalities, corporate manslaughter charges may apply.
