***********************************************************************************
     The Electrical and Mechanical Services Department (EMSD) today (May 8) announced that the department tested 28 water samples collected from cooling towers in 19 buildings in its routine inspections in April this year. Three samples were detected to have a total legionella count at or above the upper threshold, which is 1 000 colony-forming units per millilitre. The latest statistics are set out in Annex 1.

     The cooling towers in which the three samples were collected are located at Luen Cheong Can Centre, 6-8 Yip Wong Road, Tuen Mun; Katherine Building, 379 Prince Edward Road West, Kowloon City; and Block C, Hong Kong Industrial Centre, 489-491 Castle Peak Road, Sham Shui Po. The EMSD has issued nuisance notice under the Public Health and Municipal Services Ordinance to the owners of the cooling towers requiring appropriate disinfection work to be done. Disinfection of the cooling towers in these cases has already been completed by the owners. Details of the cases can be found in Annex 2.

     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 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.
