Water Tank Disinfection

Regular Water Tank Disinfection helps reduce and prevent biofilm buildup thus reducing bacteria counts and the risk of legionnaires diseases. We can also install new water tanks where required.

Sherpa Guiding you to being compliant

Legionella Risk Assessment

Becoming compliant starts with a legionella risk assessment. This will clearly identify the potential risks Legionella poses in your water systems.

Legionella Remedial Works

Once the risks have been identified they need to be monitored, removed or replaced. A plan is created to undertake any remedial works to reduce and manage the risks identified.

Legionella Monitoring

After the risks have been understood, your organisation will need to control and manage the ongoing risk of Legionella exposure from your water system to employees and visitors by carrying out ongoing monitoring.

Work Estimates

If you know the amount of water tanks you have onsite and whether you need water tank disinfection and or complete system disinfection then we can work out a price over the phone. If you are not sure it may require a quick site visit to allow us to formally quote you.

Product Performance

Let us check that your Water Tank is performing to the required standard – if the water tank is too large, water may stagnate. Sherpa can  modify the water flow layout or replace the tank with a smaller one to reduce the risk.

Quality Materials

Our fully qualified staff can carry out your water tank disinfection to the highest standards, using certified products and materials to help you meet Health and Safety guidelines.

Legionella In Water Storage Tanks

Every year unsuspecting people inhale water droplets containing deadly bacteria and contract Legionnaires diseases. Water tanks can be a source of biofilm where legionella bacteria can breed if not properly maintained thus contaminating down services such as taps, toilets and showers. For this reason, cold water storage tanks should form part of the sites legionella risk assessment and legionella control policy where regular water tank disinfection is carried out.

Water Tank Disinfection

We carry out water tank disinfection to all size’s of tanks to a very high standard, water tanks need regular maintenance and are inspected on a 6 monthly basis to keep them safe. Water sampling can be done periodically to safeguard these systems.

Regular Water Tank Disinfection helps reduce and prevent biofilm buildup thus reducing bacteria counts and the risk of legionnaires diseases.
Sherpa can also install new water tanks where required.

“Having worked with Sherpa for several years now, I have to say they are always a pleasure to deal with. Nothing is ever too much trouble… they are so organised and super reliable!

Most importantly though, they have managed to clear our legionella issues in our very old complex buildings. Thank you for your ongoing help and support – a really great crew!”

Any questions?

Here are the most common questions relating to managing legionella control, if you have any questions, you can book a call with us to see how we can help.

  • Legionella is a type of bacteria that can cause Legionnaires' disease, a severe pneumonia-like illness. It thrives in warm water environments, such as hot tubs, cooling towers, and poorly maintained water tanks.

  • Legionella bacteria spread through inhalation of aerosolised water droplets containing the bacteria. This can occur from showers, faucets, cooling towers, and other water systems where water is dispersed into the air.

  • Symptoms typically include cough, shortness of breath, high fever, muscle aches, and headaches. In severe cases, it can lead to pneumonia and even be life-threatening, especially for those with weakened immune systems.

  • To prevent Legionella growth, it's essential to:

    • Regularly clean and disinfect water tanks.

    • Maintain proper water temperature (below 20°C or above 60°C).

    • Ensure good water circulation and avoid stagnation.

    • Conduct routine inspections and testing for Legionella.

  • Water tanks should generally be cleaned and disinfected at least once a year. However, the frequency may vary based on usage, water quality, and specific regulations in your area.

  • Regulations vary by region, but many jurisdictions require regular risk assessments, maintenance of water systems, and documentation of cleaning and testing for Legionella to ensure public health safety.

  • If Legionella is detected, immediate action is required. This typically involves cleaning and disinfecting the affected system, conducting follow-up testing, and implementing measures to prevent future growth. https://www.hse.gov.uk/legionnaires/legionella-landlords-responsibilities.htm

  • Professional water management ensures that systems are properly maintained, reducing the risk of Legionella growth. Experts can provide the necessary cleaning, testing, and compliance documentation to keep your water systems safe.
