Quality Water Supply Scheme for Buildings – Flushing Water 

Introduction

To avoid failures in flushing supply, building owners and property managers have to maintain their internal plumbing systems properly. To encourage the responsible parties to do this and with the endorsement of the Advisory Committee on the Quality of Water Supplies¹, the Water Supplies Department (WSD) launched the Flushing Water Plumbing Quality Maintenance Recognition Scheme in July 2013. The scheme was re-titled "Quality Water Supply Scheme for Buildings - Flushing Water" (the Scheme) in March 2015.

E-Application 

• Objectives

  expand

  The Scheme aims to:

  1. strengthen the capability of building management agents to achieve value-added performance in meeting the expectation of consumers with respect to the reliability of flushing system;
  2. give recognition to those building management agents who can demonstrate consistent compliance of the prescribed criteria under the Scheme;
  3. assist the owners and building management agents in conducting self-assessments on plumbing conditions and to identity areas for necessary maintenance; and
  4. minimise the failure frequency of inside services of flushing system.
• The Scheme

  expand

  Participation of the Scheme is voluntary and the Scheme is a separate scheme from the current Quality Water Supply Scheme for Buildings - Fresh Water. The target groups to join the Scheme are the property owners and management agents of buildings in general. They shall submit applications to the WSD using Form C (PDF / Word) and Annex I to Form C (PDF / Word) (available on http://www.wsd.gov.hk). Besides, "Guidelines for Cleansing Flushing Water Tanks" are available on the WSD website.

  *To enhance the Scheme, WSD has added a new component (i.e. Y-Strainer/ Strainer (s)) on inspection of the plumbing systems in Table 1 of Annex I to Form C, qualified persons should include this new component for their inspections on or after 1 September 2021.

• Benefits of Joining the Scheme

  expand

  Successful buildings will be awarded certificates to recognise their proper maintenance of the flushing water plumbing systems. The names of the buildings, the owners' corporations and management agents are shown on the certificates to commend their contributions. The certificates or their copies could be displayed in those awarded buildings, stationeries and promotional materials, subject to the WSD's guidelines. The certificates are classified into three grades according to the length of the continuous period for which a building has joined the Scheme:

  Type of certificate	Length of continuous participation*	Validity
  Blue - new application	less than 3 years	1 year
  Blue - renewal	less than 3 years	2 years
  Silver - renewal	3 years or more but less than 5 years	2 years
  Gold - renewal	5 years or more	2 years

  *For continuous participation, renewal applications have to be made within 3 months before or after the expiry date of the current certificates.

  Renewals made more than 3 months after the expiry date will be considered as new applications and the validity periods of such new certificates will be reset to 1 year, starting from the new approval dates. The certificates under the Scheme are issued in recognition of proper maintenance of the plumbing systems of the buildings concerned. They are properties of the WSD, and are subject to continuous satisfactory maintenance of the systems during the validity period.

All defects identified in the inspections are promptly rectified by qualified persons.
