Water Supply

With no natural aquifers or an abundance of land, Singapore has recognised providing sustainable supply of water for its people as a vital issue in the 1960s. In the early days, we faced and overcame drought, floods and water pollution as the city grew. These challenges have inspired us to innovate and develop capabilities in this area, turning our weakness into strength.

Over the last 40 years, through strategic planning and investment in research and technology, Singapore’s national water agency PUB has built a robust and diversified supply of water known as the ‘Four National Taps’. The water supply comprises (1) local catchment water, (2) imported water, (3) highly-purified reclaimed water known as NEWater, and (4) desalinated water.

Looking back through Singapore’s water journey over half a century, we have, through investment in research and technology, found an integrated, effective and cost-efficient way to solve our water challenges.  

Our experience in effectively addressing our water challenges has earned us international recognition as a model city for water management and an emerging global hydrohub.
