The 3rd National Tap

Use Each Drop of Water More Than Once

A Singapore success story and the pillar of Singapore’s water sustainability, NEWater is high-grade reclaimed water. It is produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, making it ultra-clean and safe to drink.

Developed by PUB after three decades, NEWater has passed more than 130,000 scientific tests and is well within World Health Organisation's guidelines, a testimony of its high quality and reliability.

NEWater is proof that using today's water treatment technologies, water of any quality can be treated into drinking water. It has put Singapore on the world map for innovative water management, including winning for PUB the Stockholm Industry Water Award in 2007.

The first NEWater plants were opened in Bedok and Kranji in 2003. The latest and largest NEWater plant at Changi with a capacity of 50mgd was opened in May 2010. Currently, NEWater meets up to 30% of the nation’s current water needs. By 2060, we plan to triple the current NEWater capacity so that NEWater can meet up to 55% of our future water demand.

NEWater Usage

NEWater is mainly used for industrial and air-con cooling purposes at wafer fabrication plants, industrial estates and commercial buildings. The biggest users of NEWater are wafer fabrication plants which require water quality that is even more stringent than water for drinking. NEWater is delivered to industrial customers via a dedicated pipe network.

During dry periods, NEWater is added to our reservoirs to blend with raw water. The raw water from the reservoir then goes through treatment at the waterworks before it is supplied to consumers as tap water.

External Audit

Twice a year, NEWater undergoes rigorous audit processes by an external audit panel comprising international experts in engineering, water chemistry, toxicology and microbiology.

This high-grade reclaimed water has consistently been awarded top marks for its high quality, safety and for exceeding international standards.
