Newater Singapore: The Sustainable Solution to Water Shortages
If you’re interested in learning more about Singapore’s innovative approach to water sustainability, you’ve come to the right place. In this article, we’ll be discussing NEWater, a high-grade reclaimed water produced by Singapore’s Public Utilities Board (PUB) from treated used water. NEWater is a key component of Singapore’s water sustainability strategy, and has been in use since 2003.

Understanding NEWater in Singapore is crucial to understanding the country’s approach to water sustainability. NEWater is produced through a rigorous process of microfiltration, reverse osmosis, and ultraviolet irradiation, which results in ultra-clean, high-grade reclaimed water. This water is then used for industrial and air-con cooling purposes, and can even be blended with raw water for drinking during dry periods.
Overall, NEWater is an impressive feat of engineering and innovation, and has helped Singapore become a leader in water sustainability. In the following sections, we’ll be exploring the regulations and safety measures in place to ensure the safety of NEWater, as well as answering some frequently asked questions about this remarkable resource.

Understanding NEWater in Singapore

NEWater is Singapore’s brand of high-grade reclaimed water that is produced from treated used water. It is a key pillar of Singapore’s water sustainability and is used to cushion the water supply against dry weather, ensuring a stable and reliable water supply for the country. In this section, you will learn about the origins and development of NEWater, the NEWater process, and the uses of NEWater in Singapore.
Origins and Development of NEWater
The development of NEWater in Singapore began in the early 1990s when the government recognized the need to diversify its water supply sources. The first NEWater plant was opened in 2003 after a two-year comprehensive study, and there are currently five NEWater plants in operation. NEWater is now a vital component of Singapore’s water supply, accounting for up to 40% of the country’s water demand.
The NEWater Process
The NEWater process involves several stages, including microfiltration, reverse osmosis, ultrafiltration, and UV disinfection. The microfiltration stage removes suspended solids and bacteria from the treated used water, while the reverse osmosis stage removes dissolved solids, such as salts and minerals. The ultrafiltration stage further removes any remaining impurities, and the UV disinfection stage ensures that the water is free from any harmful microorganisms.
Uses of NEWater
NEWater is used for a variety of purposes in Singapore, including non-potable industrial uses, indirect potable use, and potable use for wafer fabrication plants, air-con cooling, and commercial buildings. The water quality of NEWater is monitored closely, and it is tested rigorously to ensure that it meets the highest standards of safety and purity.
In conclusion, NEWater is a vital component of Singapore’s water sustainability and has played a critical role in ensuring a reliable and stable water supply for the country. The NEWater process is a highly advanced and sophisticated technology that enables the production of high-grade reclaimed water that is safe for potable use. As Singapore continues to face challenges related to water supply and sustainability, NEWater will undoubtedly continue to play a crucial role in meeting the country’s water needs.
Regulations and Safety Measures

Quality Assurance and International Standards
When it comes to ensuring the safety and quality of NEWater in Singapore, PUB, the national water agency, follows strict regulations and standards. The quality of NEWater consistently exceeds the requirements stipulated in the World Health Organisation (WHO) Guidelines for Drinking-water Quality and United States Environmental Protection Agency (USEPA) Drinking Water Standards. This means that NEWater is safe to drink and meets international standards.
PUB also conducts regular quality checks and monitoring of the water source, water treatment, and NEWater plants to ensure that the water is free from viruses and bacteria. The agency also has a comprehensive quality assurance programme in place to maintain the quality of the water.
Infrastructure and Water Management
Singapore has a robust infrastructure and water management system in place to ensure that the water supply is safe and reliable. The country has four national taps – local catchment water, imported water, NEWater, and desalinated water – to ensure that there is a diversified and sustainable water supply.
The water treatment and reclamation process in Singapore involves several stages, including pre-treatment, membrane filtration, reverse osmosis, ultraviolet disinfection, and final polishing. PUB also operates several water reclamation plants and NEWater plants, including the Changi NEWater Plant, to produce high-grade reclaimed water.
In addition, Singapore has several reservoirs and waterworks, including the Marina Barrage and the Deep Tunnel Sewerage System, which help to manage the country’s water resources and ensure a consistent supply of potable water.
Overall, the regulations and safety measures in place in Singapore ensure that NEWater is safe to drink and meets international standards for drinking-water quality.
Frequently Asked Questions

What purposes does NEWater serve in Singapore?
NEWater serves as a sustainable source of water supply for Singapore. It is produced by recycling treated used water using advanced membrane technologies and ultra-violet disinfection. NEWater is ultra-clean and safe to drink, making it an important source of drinking water for Singaporeans. Additionally, it is also used for industrial and commercial purposes, such as in wafer fabrication and petrochemical industries.
How safe is NEWater for consumption?
NEWater is safe for consumption and meets the World Health Organization’s guidelines for drinking water quality. It undergoes a rigorous purification process that removes impurities and contaminants, making it ultra-clean. The PUB, Singapore’s National Water Agency, regularly monitors and tests NEWater to ensure that it meets the highest standards of quality and safety.
Can you provide a brief history of NEWater’s introduction to Singapore?
NEWater was first introduced in Singapore in 2003, following a two-year comprehensive study. The PUB, Singapore’s National Water Agency, recognized the need for a sustainable source of water supply for the country, given its limited water resources and growing population. Since its introduction, NEWater has become an important source of drinking water for Singaporeans, and has helped to ensure the country’s water security.
Where can one find the NEWater facilities in Singapore?
There are currently five NEWater plants in Singapore, located in Bedok, Kranji, Changi, Ulu Pandan, and Seletar. These plants are open to the public for visits and tours, where visitors can learn more about the NEWater production process and the importance of water sustainability.
What proportion of Singapore’s water supply is constituted by NEWater?
As of 2021, NEWater accounts for about 40% of Singapore’s water supply. The PUB, Singapore’s National Water Agency, aims to increase this proportion to 55% by 2060, as part of its long-term water sustainability plan.
How is the pricing of NEWater determined?
The pricing of NEWater is based on the cost of production and supply, and is designed to recover the full cost of its supply and production. The PUB, Singapore’s National Water Agency, takes into account factors such as capital and operating costs, as well as the cost of producing the next drop of water, which will be from desalination and NEWater. The pricing of NEWater is reviewed periodically to ensure that it remains affordable and sustainable for consumers.
