Water Supply

Water Supply Page Banner  


With limited land to collect and store rainwater, Singapore faced drought, floods and water pollution in the early years of nation building. These challenges inspired Singapore to strategise and seek innovative ideas, develop capabilities and secure a sustainable supply of water.

Four National Taps 

Today, Singapore has a robust and diversified supply of water known as the ‘Four National Taps’. Our water supply comprises:
(1) Water from Local Catchment
(2) Imported Water
(3) highly-purified reclaimed water known as NEWater
(4) Desalinated Water 

Our tap water quality is well within the Singapore Environmental Public Health (Water Suitable for Drinking) (No.2) Regulations 2019 and World Health Organisation (WHO) Guidelines for Drinking-water Quality. Water is safe for drinking directly from the tap without any further filtration.
