EMSD announces latest sampling results for legionella at fresh water cooling towers
     The Electrical and Mechanical Services Department (EMSD) today (November 7) announced that the department tested 60 water samples collected from cooling towers in 57 buildings in its routine inspections in October this year. Four 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.

     Among the cooling towers in which the four samples were collected in October, two cooling towers are located at Kwun Tong Industrial Centre Phase 4, 436-446 Kwun Tong Road, Kwun Tong, and the other two cooling towers are located at Wah Lai House, 1-9 Po Ying Lane, Tsz Wan Shan, and Tak Lee Building, 993 King's Road, Quarry Bay. The EMSD has issued nuisance notices 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 four cases has already been completed by the owners. Details of these four 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

     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.
