See case studies by relevance for risk assessment, monitoring, and cleaning, flushing and disinfection.

Relevance

  • If water is stored or re-circulated as part of your system.
  • If there are deposits (eg rust, sludge, scale, organic matter) present which could encourage bacteria growth.
  • If water droplets are produced on site (via wash / spray / showers / cooling towers etc).
  • If water temperature is between 20-45°C in all or part of your system.
  • If you pre-treat water drawn from bore-holes or if there are potential sources of contaminated water on-site.
  • If primary or secondary disinfection is required to protect water safety and improve water quality for potable and/or process water.

Water hygiene requires:

  • Risk assessments to evaluate whether suitable control measures are in place.

  • Microbiological analysis of water and UKAS-approved water testing to monitor whether harmful organisms are present.

  • Water management, water system cleaning and chlorination and control of legionella and microbiology of pipes and the water distribution system.

How we can help

We provide a full range of water hygiene services to site and contract managers, estate managers, HVAC and Duty Holders. This enables them to maintain and demonstrate exacting compliance and wellbeing for employees, visitors and the wider community – without compromise.

Water hygiene risk assessment

Formal (independent) assessment of on-site assets, water storage system condition, system hygiene, temperature checks, Legionella control measures, photographic register of assets, schematic to show the inter-relationship of equipment and risks, recommended actions, ACoP L8 risks and how to fully comply and remain safe.

Legionella risk assessment reviews

Required if there are changes to the water system or if Legionella is detected. As for a Legionella Risk Review or Update for peace of mind.

Monitoring services

Outsourced (human) and / or tech-enabled remote monitoring of temperatures, air quality, dust etc linked to risk assessments and recommended risk control measures.
