Hi, what can I do for you?



Notwithstanding that the water supplied by the Water Supplies Department (WSD) is safe to drink, the water quality could be affected in the internal plumbing systems due to various factors, such as the drinking water tank is not properly cleaned, or the internal water supply system is contaminated due to stagnation of water or use of inappropriate plumbing materials.

Therefore, WSD has been encouraging the property owners and management agents to implement water safety plan for buildings (WSPB) in their buildings to ensure the safety of drinking water in accordance with the recommendations of the World Health Organization (WHO).
