The 3rd National Tap

NEWater, a pillar of Singapore's water sustainability strategy, is high-grade reclaimed water. Produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, it is ultra-clean and safe to drink.


NEWater has passed more than 150,000 scientific tests and is well within World Health Organisation requirements.

Use Each Drop of Water More Than Once

NEWater was first mooted by PUB in the 1970s. We were ahead of our time as the membranes then were costly and unreliable. In 1998, a NEWater study was successfully conducted to determine the suitability of using NEWater as a source of raw water to supplement Singapore’s water supply. In May 2000, the first NEWater plant was completed and by 2001 we had embarked on this new initiative that would increase water supply from unconventional sources.  

NEWater Today

NEWater, Singapore's five NEWater plants can now meet up to 40% of the nation’s current water needs. By 2060, NEWater is expected to meet up to 55% of Singapore’s future water demand.

NEWater Technology

The source of NEWater is treated used water, which comes from used water that is treated to international standards and safe to be returned to nature.

Part of this treated used water from the water reclamation plant is sent to a separate system at the NEWater Plants for further treatment. At NEWater plant, the treated used water goes through a rigorous 3-step process to produce the ultra clean reclaimed water.

NEWater Usage

Non-Potable Use

As it is ultra-clean, NEWater is used mainly 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.

Indirect Potable Use

During dry periods, NEWater is added to our reservoirs to blend with raw water. The raw water from the reservoir is treated 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 the high quality, safety and for exceeding international standards.
