Fresh Water (Management System)


The Water Supplies Department (WSD) launched “Fresh Water Plumbing Quality Maintenance Recognition Scheme” in July 2002. The said scheme was re-titled “Quality Water Recognition Scheme for Buildings”, “Quality Water Supply Scheme for Buildings – Fresh Water” and “Quality Water Supply Scheme for Buildings – Fresh Water (Plus)” (Q-Plus) in January 2008, March 2015 and December 2015 respectively to signify enhancement features.

Tap water quality can be affected by various factors inherent to a building’s internal plumbing systems, despite the fact that the water supplied by the WSD is safe for consumption, such as a lack of proper cleaning of the drinking water tank, a lack of proper maintenance of the internal plumbing systems causing contamination, or the use of non-compliant materials in the internal plumbing systems. Noting this, the WSD invited expert consultants to assist in developing a set of risk-management based guidelines and templates for the Water Safety Plan for Buildings (WSPB) in accordance with the recommendations of the World Health Organization (WHO). The guidelines and templates encompass the identification of potential contamination risks in internal plumbing systems and the formulation of corresponding control measures to safeguard the quality of drinking water. The WHO welcomed the WSD’s action in devising these guidelines and templates, which are considered conducive to promoting the implementation of the WSPB. The guidelines and templates have been uploaded to a website jointly managed by the WHO and the International Water Association for international reference.

To promote building owners’ and property management agents’ adoption of WSPB, the WSD has, in consultation with the Advisory Committee on Water Supplies, combined WSPB with the Q-Plus to form a new scheme (the Scheme) to further safeguard the quality of drinking water in buildings.
