Water Quality and Legionella Testing

Assessing the risk of legionella and water quality testing

Legionnaire’s disease is a form of pneumonia contracted when legionella bacteria contaminated water is ingested. There has been an average of 370 confirmed cases of the disease in the UK over the last 10 years. Cooling towers, manufacturing processes and domestic hot and cold water systems are all susceptible to legionella colonization.

Under UK health and safety law, as an employer or person/organisation responsible for a premises such as a landlord or building owner, you have a duty to take suitable precautions to prevent or control the risk of exposure to legionella. Details of the specific law that applies can be found in part 1 of Legionnaires’ disease: The control of legionella bacteria in water systems

As a person responsible for premises, commissioning a legionella risk assessment is your responsibility and will help you to establish any potential risks and implement measures to either eliminate or control risks. 

OCS provides nationwide, comprehensive risk assessments and guidance as well as legionella awareness training for the management and monitoring of assets. We will help organisations to be aware of identified risks and ensure that they understand their duty to monitor and document a schedule of audits.
Once a legionella testing assessment has been completed, any remedial action necessary including cleaning and chlorination may be recommended which can eliminate any immediate non-compliance. If your water tanks do not comply with guidance, are affected by scale and sediment or have poor fitting or missing lids without vents or screens, we can rectify this for you.

Legionella can be fatal and assessment must be carried out by competent trained technicians. OCS will give you the peace of mind that your employees are safe from the risk of Legionella.
