Legionella Risk Assessment

Assessing risk from exposure to Legionella is not just the first step in creating a management plan, but is an ongoing process throughout out the whole lifecycle of a building.

Every building has water systems which need to be surveyed and assessed regularly to identify sources of potential risk, which then forms the basis of a scheme designed to prevent or control these risks, thereby protecting the health and safety of the bulding’s users.

Goodwater is a member of the LCA (Legionella Control Association) and is an UKAS accredited inspection body, one of just a handful of water hygiene experts to achieve this level of approval. We are fully regulated and audited which means our Risk Assessments are the best in the industry and our Assessors are the best equipped and most experienced.

The Risk Assessment itself is essentially a working document. It includes the production of schematic drawings, detailed plant surveys and plans to implement, manage and report on the various precautions identified.

According the HSE, the risks occur when water is in its aerosol state, in other words when it forms small droplets that can be inhaled, as Legionnaires’ Disease is a respiratory illness contracted through inhalation.

The main risk systems include:

  • Cooling Towers (evaporative cooling systems)
  • Domestic hot and cold water services – including tanks, calorifiers, showers and other appliances

…however spa pools, humidifiers, irrigations systems, for example, also pose risks as they too produce aerosol so must be included in any risk assessment.

We work with a variety of clients from FM companies to end users and spend time with them explaining the process and working with them to achieve a management plan that works whilst ensuring they are fully covered from a Compliance perspective.

Thereafter we can offer maintenance and remedial services and equipment solutions that may be necessary to minimise risks and bring a system up to the required standard – and more importantly keep it there, such as –

  • TMV Servicing
  • Temperature monitoring
  • Laboratory sampling
  • Cooling Tower disinfection
  • Tank and system cleaning and disinfection
  • Showerhead de-scaling
  • Deadleg removal
  • Pipework modifications
  • Chlorine Dioxide systems – supply, install and service
  • Water softeners – supply, install and service
  • UV systems – supply, install and service
  • Analytical Testing programmes
  • Inhibitor and biocide chemicals
