Although NEWater is very a very effective process, it has a couple of disadvantages. NEWater will not be able to produce enough potable water to be independent. It is now only able to produce 30 percent of Singapore’s demand . In the future, 2060, it is predicted to meet 55 percent of Singapore’s demand.
Is NEWater energy efficient?
Desalination is an energy-intensive water source. Singapore currently uses reverse osmosis for its desalination, which uses about 3.5kWh/m3 of energy to make seawater drinkable. This process produces pure drinking water by pushing seawater through membranes to remove dissolved salts and minerals.
Why is NEWater expensive to produce?
Rainwater is collected through a comprehensive network of drains, canals and rivers, and channelled to reservoirs before it is treated to become drinking water. Desalination is the most energy-intensive of our four taps. This makes desalinated water the most costly to produce.
How is NEWater produced?
Procedure. NEWater is produced by a multiple-barrier water reclamation process : ... The filtered water after passing through the membrane contains only dissolved salts and organic molecules. second stage of the NEWater production process, uses reverse osmosis (RO).
Is NEWater safe to drink?
NEWater is high-grade reclaimed water 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 .
Why do Singaporeans drink urine?
A parody of a popular nationalist song, “Count on Me, Singapore,” cheerily urged residents to “Drink Our Pee, Singapore.” The queasy reactions of some Singaporeans didn’t deter the utility, which built four more wastewater treatment plants and is about to increase its NEWater production to 555 megaliters a day.

How is NEWater treated?
NEWater is recycled from treated sewage (‘used water’) and produced using a rigorous 3-step purification process involving ultrafiltration/microfiltration, reverse osmosis (RO) and ultraviolet (UV) disinfection.
How do we know if an appliance is energy efficient and saves energy?
Look for the bright yellow EnergyGuide label on an appliance to compare energy-efficient refrigerators and how much energy they use.
Does desalination use a lot of energy?
Energy consumption is one of the biggest hurdles desalination faces. ... The high-pressure system used to desalinate salt water requires a high amount of energy to do. Billions of gallons of water are forced through the pressure treatments, consuming an average of 10-13 kilowatt hours (kwh) per every thousand gallons.
How much does a bottle of water cost in Singapore?
| Restaurants Edit | Water (1.5 liter bottle) 1.59S$ | Bottle of Wine (Mid-Range) 30.00S$ | Domestic Beer (0.5 liter bottle) 5.27S$ | Imported Beer (12 oz small bottle) 5.53S$ |

Which NEWater plants is the largest in Singapore?
The Sembcorp NEWater Plant marks a major step in Singapore’s water sustainability journey with its total capacity of 50 million imperial gallons, or 228,000 cubic metres, of NEWater per day.
Where does Singapore get its water supply?
Currently, Singapore has built a robust and diversified supply of water from 4 different sources: water from local catchments, imported water, NEWater (high-grade reclaimed water) and desalinated water .
Why was NEWater created?
The project was revived when PUB and the then Ministry of the Environment (ENV), now called the Ministry of the Environment and Water Resources, initiated the Singapore Water Reclamation Study (NEWater Study) in 1998 to determine if NEWater could be a viable source to supplement Singapore’s water supply.
Is NEWater desalinated?
Singapore has built a robust, diversified and sustainable water supply from four water sources known as the Four National Taps – Water from Local Catchment , Imported Water, high-grade reclaimed water known as NEWater and Desalinated Water.
Is reverse osmosis used in NEWater?
The filtered water that goes through the membrane contains only dissolved salts and organic molecules. The second stage of the NEWater production process is known as Reverse Osmosis (RO). ... Hence, NEWater is RO water and is free from viruses, bacteria and contains negligible amount of salts and organic matters.
