Following a Legionella risk assessment, it is likely that some corrective or improvement works are identified to bring your water system up to compliance.

How we can help you

Our experienced engineers have confronted a wide range of site issues, so you can be reassured we will recommend the most efficient corrective or improvements solution for your needs.

Corrective or improvement works can include:

Water tank cleaning and disinfection

Following routine inspection, cleaning and disinfection of the water tank and services is recommended when there is visible evidence of sediment, biofilm, flora growth, stagnant water animal contamination and corrosion.

Backflow prevention

Water regulations state that every fitting through which water is supplied for domestic purposes should be installed in such a manner that no backflow can take place. We fit double check valves which are devices consisting of two valves which permit water flow only in one direction.

Example control measures:

  • Staff training
  • Flushing of rarely used outlets
  • Descaling taps
  • Temperature monitoring (Inc. sentinel points)
  • Records audit
  • Servicing Thermostatic Mixing Valves (TMVs) and Integrated Filters
  • Showerhead clean and descale
  • Water tank inspection (annually)
  • Water tank temperature checks (6 monthly)
  • Potable water tank TVC & Legionella sampling
  • Calorifier inspection and blowdown
  • Calorifier flow & return temperatures

Legislation

ACoP L8, The control of legionella bacteria in water systems, paragraph 39:

"If the risk assessment shows that there is a reasonably foreseeable risk and it is reasonably practicable to prevent exposure or control the risk from exposure, the person on whom the statutory duty falls should appoint a person or persons to take a managerial responsibility and to provide supervision for the implementation of precautions"

Record Keeping

Perhaps the single most important aspect of any Legionella management programme is keeping a record of monitoring results and findings.

We will issue each site with a hard copy or electronic log book depending on your requirements. These log books contain standard documentation and site specific information which fully complies with the requirements of ACoP L8.

The key sections of this user-friendly operating and record keeping manual are:

  • Lines of communication and appointed personnel
  • Significant findings from the Legionella risk assessment
  • Written control scheme
  • Monitoring and inspection results
  • Monitoring and inspection templates (when site is undertaking actions)
  • Remedial and attendance logs

How we can help you

Bradley Environmental can assist you with the operational management of Legionella control. Our monitoring and inspection programmes are designed in strict accordance with ACoP L8 to keep you compliant.
Services are carried out under internal procedures which have been accredited by the Legionella Control Association to ensure year round compliance and quality of service to our clients.
Each monitoring contract is assigned an account manager who is responsible for planning all works and liaising with you at all times, providing you a single point of contact.

Re-orientate expansion vessels

They need to be orientated vertically with the drain point at the bottom. This allows water to drain out and not sit and become stagnant.

Dead leg removal

These are lengths of unused pipe work as small as 15mm which have little to no water flow, for this reason water becomes stagnant creating a breeding ground for Legionella bacteria. They need to be cut back as far as possible.

Pipe work and cold-water storage tank insulation

Carried out to minimise heat loss/gain. Loss of heat through lack of insulation and heat gain of tanks and pipe work through exposure to high temperatures and/or proximity to hot water pipes.
