***********************************************************************************
     The Electrical and Mechanical Services Department (EMSD) today (October 10) announced that the department tested 107 water samples collected from cooling towers in 102 buildings in its routine inspections in September this year. Six 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 six samples were collected in September are located at Grandview Building, 49-69 Fa Yuen Street, Mong Kok; Kam Lok House, 152 Un Chau Street, Sham Shui Po; 259 Apliu Street, Sham Shui Po; 322-322A Un Chau Street, Cheung Sha Wan; Lee Wo Building, 124-136 Wo Yi Hop Road, Kwai Chung and Zung Fu Industrial Building, 1067 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 six cases has already been completed by the owners. Details of these six 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 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.
