The Quality Water Recognition Scheme for Buildings (QWRSB) Certificate Presentation Ceremony 2011 was held at the Regal Riverside Hotel in Shatin on 30 August 2011. Certificates were awarded to property owners, owners' corporations, property management companies, and management agents of hospitals, hotels, schools, universities and public institutions to recognise their efforts in proper maintenance of their fresh water plumbing systems. The total number of buildings awarded with Gold and Silver certificates under the QWRSB had significantly increased from about 1,300 last year to nearly 1,600 this year.
