UKAS Water & Legionella Testing

Mawdsleys Water Testing Services

All of our water testings are sent to an independent UKAS Accredited Laboratory.

Mawdsleys Pump Services are able to take samples for microbiological testing including Legionella, e-Coli, Coliforms, Pseudomonas and much more. All completed tests come with a certification of the results and where necessary a report with remedial works required.

Drinking Water Quality Test

Legionella Testing

Do I need a Legionella Risk Assessment?

If you are responsible for a hot and cold water system then you have a legal obligation under current Health and Safety to assess whether there is a risk posed by exposure to legionella, from hot and cold water systems or any work associated with it.

Mawdsleys Pumps Legionella Risk Assessment

Our risk assessor will consider all aspects of the operation of hot and cold water systems. We will specify the various control measures, how to use and carry out those measures, describe the water treatment regimes and the correct operation of the water system.

We will identify a management structure, provide up-to-date schematic plans showing the layout of the system and its location within and around the premises. We will identify remedial action to be taken to reduce the risk, and leave you with an ongoing management system. The Legionella Management System will delegate duties to ensure that the necessary precautionary measures are maintained, and levels of responsible authority will be laid down.

At Mawdsleys Pump Services we have fully trained surveyors who undertake the necessary risk assessments to ensure compliance with the Health & Safety Commission Approved Code of Practice: Legionnaires disease the control of legionella bacteria in water systems.  Your risk assessment is presented as a report which includes images and an easy to understand action list for those with the statutory duty, enabling them to prioritise the work required to control legionella.

As part of our service offering, we can carry out cold water tank maintenance including repair and replacement of essential pipework.

Where Might Legionella Be Present?

All man made hot and cold water systems provide an adequate environment for legionella to grow, but there are factors which can impact how well it thrives:

  • The presence of rust, sludge, scale or biofilm can promote growth.
  • If the water is stored rather than recirculated.
  • The temperature, legionella thrives between 20-45c but will die at 60c.

Additionally, the water temperature and whether the water is stored or recirculated can impact how well the bacteria grows. Legionella can thrive in all water systems of all sizes, but particular attention should be paid to:

  • Cooling towers
  • Hot and cold water systems
  • Evaporative condensers
  • Spas and swimming pools
  • Humidification plants

Who Is Responsible for Controlling the Risk of Legionella?

As an employer, or person in control of premises, you must appoint someone competent to help you meet your health and safety duties and to take responsibility for controlling any identified risk from exposure to legionella bacteria.

A competent person, often known as the responsible person, is someone with sufficient authority, competence, necessary skills, knowledge of the system, and experience.

Under the Health and Safety at Work etc Act 1974, the responsible person must understand how to:

  • Identify and assess sources of risk.
  • Manage any risks.
  • Prevent or control any risks.
  • Keep and maintain the correct records.

The BSI British Standard BS7592:2008 Sampling for Legionella Bacteria in water systems is the code of practice that needs to be adhered to by law.
