During routine inspections, the Electrical and Mechanical Services Department tested 99 water samples collected from cooling towers in 62 buildings in September. Four samples were found to have a total legionella count at or above the upper threshold, which is 1,000 colony-forming units per millilitre. Disinfections of the cooling towers in these cases have already been completed by the owners.
The cooling towers in which the samples were collected are located at Ming Sau Building, 91A Chun Yeung Street, Eastern; Hong Kong Garden Commercial Centre, 100 Castle Peak Road, Tsing Lung Tau, Tsuen Wan; 9 & 33-36 Sham Hong Road, Tsuen Wan; and Cheung Fung Industrial Building, 23 Pak Tin Par Street, Tsuen Wan.
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.
