Legionella

Legionnaires’ disease is a form of pneumonia, caused by Legionella bacteria. Legionnaires’ disease comes from breathing in bacteria contained in small droplets of water, like spray from a shower or taps.

WWHC has a robust management system for maintaining and monitoring our water systems. Our multi-storey properties are served by cold-water storage tanks and we have a specialist water hygiene contractor who inspects and tests the water in these tanks regularly. We also carry out additional follow up works and regular tank cleaning based on our contractor’s recommendations as and when required.

Please be aware that Legionnaires’ disease is rare, and you cannot contract it from another person nor by drinking tap water.   

The bacteria cannot multiply in temperatures below 20°C or survive above 60°C. Stagnant water stored between 20°C and 45°C provides the best conditions for the bacteria to grow and multiply.

Legionella bacteria can be found in most water systems and most people will not experience any health problems.

You can keep the number of bacteria low and prevent disease in your home by following these simple steps:

• To prevent the build-up of bacteria, you should flush out taps and outlets that you do not use often, at least once a week. Run the water through these outlets for roughly 5 minutes.
• To prevent the bacteria being released into the air, you should descale your taps and shower head at least every three months using a household disinfectant cleaning product.
• External hose pipes should be flushed through for several minutes each time they are used, without creating a spray – this is most important during the warmer seasons.
• Water from hot taps should be at a minimum temperature of 50°C – be careful of scalding and remember to supervise children at all times.
• Immediately report any concerns about low hot water temperatures, poor water flow, defective taps, boiler issues or any else unusual from your taps
