Construction of an additional Newater factory at Changi’s used water reclamation plant will begin in 2024 following the completion of an environmental impact assessment. It had concluded that discharge from the new factory would not affect the marine environment.
This factory will join two existing ones at the Changi Water Reclamation Plant (WRP) and will cater to the growing demand for water, ensuring that Singapore’s water production is climate-resilient. It is expected to be completed in 2026.
Plans to build the factory were announced in 2020, but its construction could not be carried out until the environmental impact assessment of its development and operations was completed.
Singapore currently has five Newater factories – two in Changi, and one each in Bedok, Ulu Pandan and Kranji.
The new factory will replace the ageing 20-year-old one in Bedok, which national water agency PUB plans to decommission to free up space for other needs.
To produce Newater, treated used water is purified by reverse osmosis. Ultraviolet light is used to remove any remaining viruses or bacteria in the water.
The new Newater factory will receive treated used water from Changi WRP and produce up to 50 million gallons of Newater per day, said PUB. This is equivalent to what the two existing factories at Changi produce a day, and is more than twice the capacity of the Bedok factory, which produces 18 million gallons of water per day.
Newater is mainly supplied to wafer fabrication plants, industrial estates and commercial buildings. By 2065, two-thirds of Singapore’s water demand is expected to come from non-domestic sectors.
