Water treatment for hospitals
Critical systems, vulnerable patients, and no acceptable margin for error. Eleven hospitals run on Gotech live monitoring.
Hospitals are the highest-stakes water systems in Hong Kong: the occupants are, by definition, the people most vulnerable to Legionella. Eleven hospitals currently run on Gotech real-time monitoring, with pH, chlorine and other parameters tracked around the clock and dosed automatically.

The systems we look after
What is actually at risk
Legionnaires' disease is far more dangerous in an immunocompromised population. A count that would be a compliance problem in an office is a clinical problem in a hospital. Oversight is correspondingly heavier, and the documentation burden is real.
Why Gotech fits
- Eleven hospitals currently on Gotech real-time monitoring
- Continuous data rather than a reading once a month
- Automatic dosing with alarms when a parameter drifts
- Water-treatment works delivered for the EMSD's E&M Services Department at Hong Kong public hospitals
- Documented to the EMSD Code of Practice, every visit
Client names, including hospitals and government sites, are kept private. Full reference lists are shared with quotations on request.
Frequently asked questions
How is Legionella controlled in hospital water systems in Hong Kong?
Through continuous treatment and continuous measurement. Eleven Hong Kong hospitals currently run on Gotech real-time monitoring, with pH, chlorine and other parameters tracked around the clock, dosed automatically, and alarmed when a reading drifts — continuous data rather than a reading once a month, documented to the EMSD Code of Practice at every visit.
Why do hospitals need stricter water treatment than other buildings?
Because the occupants are, by definition, the people most vulnerable to Legionella. Legionnaires' disease is far more dangerous in an immunocompromised population, so a count that would be a compliance problem in an office is a clinical problem in a hospital — and the oversight and documentation burden are correspondingly heavier.
Does Gotech work in Hong Kong public hospitals?
Yes. Gotech works under the Electrical & Mechanical Services Department as owner/agent on public hospital sites, covering cooling towers, potable and hot water, and chilled water. Client names, including hospitals and government sites, are kept private — full reference lists are shared with quotations on request.
