Quality Water Supply Scheme for Buildings – Flushing Water 


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.
