Water treatment works
NEWater reclamation plants
Singapore’s planned potable reuse system, treating secondary effluent by microfiltration, reverse osmosis and ultraviolet disinfection to a quality exceeding drinking water standards.
Key facts
- Operator
- PUB Singapore
- Treatment train
- Microfiltration → reverse osmosis → ultraviolet disinfection
- Share of national water demand
- Up to around 40% at full capacity
- Principal use
- Industrial ultrapure supply, with indirect potable reuse via reservoirs
Context
NEWater is the most successful large-scale demonstration of planned potable reuse anywhere. Most of the output goes to industry, where the very low mineral content is an advantage; a portion is blended into reservoirs before conventional treatment, which is indirect potable reuse. The public acceptance strategy — extensive visitor education and a visible political commitment — is studied as closely as the treatment train.
