The Kai Ching estate, in the middle of the Lead (Pb) ‘scandal’ and the Legionella case associated with Mun Ching House achieved the WSD (http://www.wsd.gov.hk) Quality Water Recognition Scheme for Buildings certification! (see image below). Lead (Pb) is not one of water quality parameters tested.
In the past I highlighted Hong Kong’s building water quality issues (here) but my office building is not listed above, I am certain that WSD will revise the criteria after this incident. So far Lead (Pb) contamination of the residents water has been detected in the following sites:
- Kai Ching Estate, Kowloon City
- Kwai Luen Estate, Kwai Chung
- Shui Chuen O Estate, Sha Tin
updated: 17 July 2015
Late yesterday (16 July 2015) WSD published a circular letter no. 1/2015 (Chinese only) online, dated 13 July 2015, it now requires Flats (subject to interpretation) to provide a declaration letter for No Lead in solder, and additional water quality testing parameters in the laboratory report, including:
Lead (Pb) ≤10 μg/l
Cadmium (Cd) ≤3 μg/l
Chromium (Cr) ≤50 μg/l
Nickel (Ni) ≤70 μg/l
Needless to add that these new requirements only apply to new water meter applications. However, the estimated to be 50,000 renovation projects per year, are not required to conduct any type of water quality test!
