TestHub Laboratories carries out documented Legionella Risk Assessments for commercial properties across Dubai and the wider UAE, covering cooling towers, tanks, and domestic water systems throughout your building.
Why Your Building Needs This
Warm climates like Dubai’s create ideal conditions for Legionella to grow: water that sits still, a dead leg of pipe, an idle cooling tower, all in temperatures where the bacteria thrives. Add aerosol-generating equipment like cooling towers, showers, or spa jets, and there’s a direct route for that bacteria to reach someone’s lungs.
A documented risk assessment gives regulators and insurers across the UAE a paper trail showing the hazard was identified and controlled, not just a maintenance log that says the system “should be fine”.
Benefits of a Legionella Risk Assessment
- Health protection — reduces the chance of Legionnaires’ disease spreading through your building’s water systems
- Complaince — gives you documented evidence for regulators, auditors, and insurers
- Risk reduction — catches hazards like stagnant water or temperature gaps before they become a positive test result
- Preventive maintenance — turns your maintenance schedule into a targeted plan instead of guesswork
Who Needs a Legionella Risk Assessment?
Anyone responsible for a commercial building’s water system carries this duty, not just the buildings themselves. That includes:
- Building owners and landlords with shared water systems
- Facility and property managers overseeing day-to-day operations
- Hotel and hospitality operators with pools, spas, and cooling towers
- Healthcare administrators responsible for patient safety
- Developers and contractors handing over a completed building
- Any business operating a cooling tower, water tank, or shared plumbing system
What We Check
Buildings We Assess
- Hotels and serviced apartments
- Hospitals, clinics, and care facilities
- Office towers and commercial complexes
- Shopping malls and mixed-use developments
- Residential towers with shared water systems
- Industrial and manufacturing facilities
- Schools, universities, and labour accommodation
Water Systems We Assess
- Cooling towers and evaporative condensers
- Domestic hot and cold water systems
- Water storage tanks
- Swimming pools and spa pools
- Showers, spray taps, and other aerosol-generating outlets
- Humidifiers and misting systems
Our Process
1. Site Survey
We trace your water system from source to outlet, noting pipework, tanks, dead legs, and anything that could let water sit still or heat up.
2. Hazard Identification
We flag the specific conditions on-site that support Legionella growth: temperature gaps, corrosion, and low-use outlets that don’t get flushed.
3. Risk Rating
Each hazard is rated for likelihood and consequence, so you know what to fix first.
4. Water Management Plan and Report
You get a written report with risk ratings, photographic evidence, control measures, and a monitoring schedule.
What You Get
- A full water system survey covering every relevant outlet and system
- Temperature checks at key points across the building
- A review of existing maintenance and water treatment records
- Hazard identification with risk scoring
- A written report with corrective actions
- A recommended reassessment schedule
Risk Assessment vs. Legionella Testing
The risk assessment sets the plan. Testing checks that the plan is working.

FAQ
What is a Legionella risk assessment?
A structured review of your water systems to find where Legionella could grow, plus the control measures needed to manage that risk.
How is it different from Legionella testing?
- Testing analyses a water sample for bacteria. A risk assessment looks at the whole system to find the conditions that let it grow in the first place.
Which buildings need one?
Any building with a water system capable of generating aerosols: hotels, hospitals, offices, malls, residential towers, and industrial sites.
How often should it be reviewed?
Annually, or sooner after a system change, a positive result, or a long period when the building has been unused.
Can TestHub handle both testing and risk assessments?
Yes. Both sit under one roof, so your assessment findings and lab results come from the same team.
What happens after the assessment?
You get a written report with risk ratings and recommended actions, plus help setting up a testing and monitoring schedule.
Do UAE regulations require a Legionella risk assessment?
Dubai Municipality and other UAE authorities require regular water safety checks for cooling towers and building water systems, including periodic testing. A documented risk assessment is the standard way facility owners demonstrate they’ve identified and controlled that hazard, and it’s often requested during audits or insurance reviews.
