Legionella Risk Assessment

Goodwater is a member of the LCA (Legionella Control Association) and a UKAS accredited inspection body under BS EN ISO/IEC 17020:2012 for hot and cold water systems.

Goodwater are one of just a handful of water hygiene experts to achieve this level of approval.

Assessing risk from exposure to Legionella is not just the first step in creating a management plan, but is an ongoing process throughout 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 building’s users.

We are fully regulated and the competency of our assessors is regularly independently audited which means our hot and cold water Risk Assessments can be considered amongst the best in the industry.

The Risk Assessment itself is essentially a working document. It involves the undertaking of detailed site surveys, production of schematic drawings, and details plans to implement, manage and report on the various risks identified.

According to the HSE, the primary route of infection of Legionnaires’ Disease is through the inhalation of dispersed aerosol (fine droplets of water) contaminated with legionella bacteria.

The main risk systems include:

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

…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
