The Importance of Legionella Remedial Works

Legionella Remedial works focus on improving the design of your water system by removing risks that encourage growth. Once you have the
Legionella Risk Assessment, this will help identify all the risks and the practical steps that should be taken. The first step is to always eliminate the risk. Alternatively, when the risk cannot be removed the action is to reduce the risk.  For example, the removal of redundant pipework, however, if pipework cannot be removed then implementing a weekly flushing regime is essential.

Techright Environmental provides practical advice and solutions to all are Northern Ireland clients. We pride ourselves on:

        Legionella Remedial Work Actions  

        After undertaking the legionella risk assessment, you will need to remove or reduce the risk. To demonstrate, the Remedial Team will complete the actions identified in this risk assessment.  

        Firstly, we will supply and fit with a new lid with a R31 tank breather and ingress screens. The pipes and tank will be insulated to provide protection from heat loss or transfer. 

        Secondly, the pipework will be re-routed to ensure the Inlet and Outlet are on opposite sides of the water tank. As a result, this will provide a good crossflow of water, that will help reduce water stagnation.

        Thirdly, the ballcock will be replaced, and in this case, lowered to reduce the stored water volume. With less staff onsite and working at home the volume of water turnaround was identified. These works will not need to be carried out again. 

        Finally, we will clean and chlorinate the water tank. In addition, we will produce a tank chlorination certificate. Furthermore, we will collect microbiological samples.

        Some of these works will only need to be actioned once. The water tank should be inspected periodically and cleaned when necessary.


        All Remedial Works is in line with L8 and ACOPs 

        All Remedial Work will be carried out in line with WRAS and Regulatory Standards. The certified and competent consultants who work to a high set of standards are fully trained. Giving you the reassurance and confidence that your water system is safe, compliant and efficient.

        As a result, this will help lower the chances of a Legionella outbreak.

        Finally, we will produce completion report showing photos of all the completed works. This way you will have evidence and proof of works.
