About your Legionella remediation

Project managed - Removing Legionella bacteria - Complete data logs - Ongoing support

There are many ways of removing Legionella bacteria and to prevent it occurring in the first place. It may be that you need to adjust your water system’s design, for example, by removing a dead leg.

In other cases professional cleaning and disinfection is the most appropriate solution.

There are two commonly adopted approaches for disinfecting water services.

  • Thermal disinfection. We would increase your hot water system temperature. Legionella bacteria cannot survive in higher temperatures. Next, we would draw the hotter water through to every outlet. Slow flow rate flushing is then completed for a predetermined period of time.
  • Chemical disinfection. We would complete this by adding an effective agent such as chlorine to your water system. We would then draw this through to every outlet. Closing each outlet to allow it to remain in contact for a suitable period of time.

For more complex water systems you should get a site specific method statement. We appoint a consultant to provide a method statement for your works. We review it for suitability. If necessary, we can recommend any needed adjustments.

Once we approve the method statement, we can then project manage the on-site works. This removes the hassle from the process, enabling you to focus on your business. It also ensures that your remediation works are effective.

On completion of your disinfection project, one of our P901 qualified consultants will attend site. They will collect water samples and arrange for them to be tested for Legionella. If needed we will assess other indicative bacteria levels.

Only when you get satisfactory results can you consider the system safe. We will process the results and confirm this for you.

If you need further disinfection works, we will include this within your original quotation. This provides you with complete peace of mind; from both a financial and safety perspective.

Customer Portal

If you have appointed us to complete your Legionella risk assessment, you will have access to our portal. We will record details of all remediation works completed on this system. Should you ever have to provide evidence of how you have managed the risk of Legionella bacteria, it will provide you with complete records.
