How was NEWater created?
Procedure. NEWater is produced by a multiple-barrier water reclamation process: first stage of the NEWater production process, uses microfiltration/ultrafiltration to remove suspended solids, colloidal particles, disease-causing bacteria, some viruses and protozoan cysts. At this stage, the water is of potable quality.
Is Singapore tap water NEWater?
NEWater is one of Singapore’s four national taps. In fact, NEWater is cleaner than PUB water. Here’s why. Note: PUB Water/Tap Water is well within the World Health Organisation (WHO) drinking water guidelines, and is suitable for drinking without further filtration.
Where do Singapore’s water supply come from?
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.
Why is NEWater expensive?
The latest NEWater plant is one of the major investments in water infrastructure to strengthen Singapore’s resilience against weather uncertainties, he added. Water costs are being driven up by the rising costs of asset maintenance and replacement, as well as resources like energy, chemicals, materials and manpower.
Will Singapore ever run out of water?
Singapore, a steamy, low-lying island city-state, is the fifth most likely country in the world to face extremely high water stress by 2040, according to the U.S.-based World Resources Institute.
Which country has the cleanest drinking water?
Switzerland
1) Switzerland Switzerland is repeatedly recognized as a country with the best quality tap water in the world. The country has strict water treatment standards and superior natural resources with an average rainfall per year of 60.5 inches. In fact, 80% of the drinking water comes from natural springs and groundwater.
What are some advantages of NEWater?
NEWater improves Singapore’s water security, increases its resilience to climate change, and also reduces the need for large water storage capacity as water is constantly recycled, thereby freeing up limited land for other uses.
Why does Singapore have no water?
Singapore is considered to be one of the most water-stressed countries in the world. It is heavily dependent on rainfall due to the lack of natural water resources, and limited land is available for water storage facilities. Prolonged dry spells cause or threaten to cause water shortages, the most recent being in 1990.
Where is the cleanest air on Earth?
Puerto Rico
Puerto Rico, an unincorporated territory of the United States, has the cleanest air in the world, followed by the French territory of New Caledonia in the Pacific Ocean with the territory of the US Virgin Islands in third.
What kind of water does NEWater NEWater use?
NEWater NEWater, Singapore’s success story and a pillar of water sustainability, is a high-grade reclaimed water produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, hence making it ultra-clean and safe to drink.
How does the NEWater water plant in Singapore work?
NEWater. The NEWater process recycles our treated used water into ultra-clean, high-grade reclaimed water, cushioning our water supply against dry weather and moving Singapore towards water sustainability. Today, there are five NEWater plants supplying up to 40% of Singapore’s current water needs.
Where is the best place to use NEWater?
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.
Why was NEWater called a water reclamation plant?
The PUB was cautious in its usage of terms, avoiding terms such as ‘wastewater’ or ‘sewage’ that carried a negative connotation. Sewage treatment plants were renamed to ‘water reclamation plants’ and sewage or wastewater were referred to as ‘used water’. This contributed to a positive framing of NEWater, enhancing public acceptance of reused water.
