Seeing What the Industry Has Been Missing
Every year, thousands of people across the UK are hospitalised with Legionnaires' disease. Between 4,000 and 6,000 cases are recorded annually, and between 7-12% of those infected don't survive. And in almost every case, the bacteria responsible, Legionella pneumophila, was already present in a water system that someone, somewhere, was responsible for managing.
What makes that harder to bear is this: 90% of people in the UK know little or nothing about Legionella. Only 11% of us think to check taps and showers as part of our cleaning routine. The public isn't ignoring the risk, they simply don't know it exists.
That's what makes the professionals in this industry so important. Engineers, facilities managers, water safety consultants, estates teams, contractors, you are the first line of defence between a vulnerable building occupant and a preventable outbreak. The knowledge, the monitoring programmes, the compliance frameworks, they exist because you make them happen.
Hydrosense was built to support that work.
Based in Edinburgh, Hydrosense has spent over two decades developing rapid, on-site Legionella detection technology designed to sit alongside existing water management control plans - adding a layer of fast, field-ready intelligence between scheduled monitoring intervals. Results in 25 minutes. No laboratory required. No waiting.
Their latest innovation, Hydrosense PRO, takes that capability further than any rapid test has gone before. Where earlier rapid detection tools focused solely on Legionella pneumophila serogroup 1, Hydrosense PRO detects all serogroups 1-15. Using a proprietary three-line lateral flow test and an exclusive filtration step, it independently identifies serogroup 1 and serogroups 2-15 at a sensitivity of 100 CFU/L, giving the granular picture that informs remedial decisions, shapes reporting, and shortens the time between detecting a risk and acting on it.
Crucially, the technology's accuracy has now been independently validated. An extensive third-party study conducted by CDC ELITE and ISO/IEC 17025:2017 certified laboratory CHEM Inc. in California tested Hydrosense PRO alongside traditional lab culture methods using CDC reference Legionella materials. The outcome was unambiguous: Hydrosense PRO was 100% accurate in identifying both L. pneumophila serogroup 1 and serogroups 2-15 from blind samples, delivering comparable results to lab culture, but in 25 minutes rather than seven days.
For healthcare estates managing complex water systems and immunocompromised patients, for hospitality operators where a single outbreak can be devastating, for infrastructure teams and contractors across large-scale sites, this is technology built to work in the environments you work in, not just a laboratory setting.
Already trusted by NHS estates teams, facilities management providers, water utilities and compliance professionals across the UK and internationally, Hydrosense PRO is designed to complement, not replace, established testing and monitoring protocols, strengthening the overall picture of water safety for the people who need it most.
Because the public may not know the risk. But you do. And Hydrosense is here to help you stay ahead of it.
Hydrosense sees what you can't.
