NEWater, Singapore’s third National Tap, is high-grade reclaimed water purified with advanced membrane technologies and ultraviolet technologies.
sustainable water supply over the decades. In a move to become a smart utility of the future, we are increasingly leveraging digital solutions and smart technologies to improve operational ef ciency and deliver better service to customers. Some of these initiatives include Smart Water Meters and Smart Shower devices for customers to better track their water usage, and pre-emptive leak management system to detect potential pipe failures and prevent pipe leaks.
PUB’s strong commitment to innovation has also helped us build capabilities in water management. Water and environment technologies have been identi ed as a key growth sector since 2006, with S$670 million committed to foster leading-edge technologies and create a thriving research community in Singapore. Today, there is a vibrant water ecosystem with over 200 local and international water companies and more than 25 research institutions.
Since 2008, Singapore has successfully hosted the Singapore International Water Week (SIWW). As the global platform for innovative water solutions, stakeholders from the world’s water industry gather at SIWW to share business opportunities, showcase the latest water technologies and co-create solutions.
Explore collaborations and innovative water solutions within a vibrant ecosystem of companies, research institutions and water leaders. Experience Singapore’s “living laboratory” and learn how sustainable water management is essential to liveable cities. Shape the future of water and cities at SIWW, the world’s only integrated event on water and urban sustainability.
The Stamford Detention Tank, together with the Stamford Diversion Canal, are designed to offer long-term flood protection for Orchard Road by detaining, delaying and diverting stormwater runoff.
Singapore one of the few countries in the world to harvest urban storm water on a large scale for its water supply.
The introduction of NEWater in 2003 was a major milestone. This ultra-clean, high-grade reclaimed water is a Singapore success story and the pillar of our water sustainability. NEWater is produced by further purifying treated used water using advanced membrane technologies – namely, micro ltration, reverse osmosis and ultraviolet disinfection – making it ultra-clean and safe to drink. Today, Singapore has 5 NEWater plants producing this high-grade reclaimed water for use in industry.
Desalinated water has been a part of our water supply since 2005 when Singapore’s  rst desalination plant was opened. Today, Singapore has three desalination plants with the third at Tuas opened in 2018. Two more desalination plants at Marina East and Jurong Island will
be completed this year to further strengthen Singapore’s water supply resilience.
Our approach to water management can be distilled into three key strategies: collect every drop of water; reuse water endlessly; and desalinate more seawater.
PUB also works with the community and reach out to a wide group of stakeholders to improve their water consumption habits. We adopt a multi-pronged approach to this: pricing water to re ect its scarcity value; mandating water ef ciency standards; and encouraging water conservation practices.
PUB has been investing in research and technology to meet Singapore’s water challenges, and deliver for Singapore a robust, clean and
