EMSD announces latest sampling results for legionella at fresh water cooling towers

The Electrical and Mechanical Services Department (EMSD) today (August 7) announced that the department tested 72 water samples collected from cooling towers in 45 buildings in its routine inspections in July 2026. None of them were detected to have a total legionella count at or above the upper threshold, which is 1 000 colony-forming units per millilitre. 

The EMSD also announced the locations of buildings which were served with nuisance notices during the preceding three-month period as the total legionella count was found in the fresh water cooling towers to be equal to or above the upper threshold. 

The EMSD publishes the latest statistics of the above information on a half-monthly basis on its website:

www.emsd.gov.hk/en/other_regulatory_services/cooling_towers/water_sampling/index.html.

The EMSD reminds the owners of fresh water cooling towers that they have the responsibility to design, operate and maintain cooling towers properly. They should arrange regular inspections, timely maintenance and periodic testing of the water quality in their cooling towers in accordance with the Code of Practice for Fresh Water Cooling Towers issued by the department to prevent the proliferation of legionella.
