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.
Why is it important for Singapore to have different sources of water?
Both NEWater and desalinated water have allowed Singapore to become more resilient towards weather variability and keep up with the growing demand for water resources. By 2060, the total water demand could almost double, with the non-domestic sector accounting for nearly 70%.
How does Singapore improve water quality?
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.
What are the 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.
What does Singapore water contain?
Singapore’s tap water contains small amounts of chlorine, pesticides, lead and other heavy metals, nitrates, nitrites, fluoride and possibly other people’s medical drugs. Why? The chlorine and fluoride are added to kill bacteria and allegedly strengthen our teeth.
What is Singapore’s main issue with 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.
Will Singapore ever run out of water?
Without importing millions of litres from Malaysia every year, Singapore would simply not survive. Seah’s job is to find new ways to keep Singaporeans topped up with their blue gold. The population is rapidly growing, and demand will have doubled by 2061 – the end date for the country’s import agreement with Malaysia.
What can Singapore do better in sustaining our environment?
Singapore has taken early measures on sustainable development, such as managing the growth of our vehicle population and making the switch from fuel oil to natural gas, the cleanest form of fossil fuel, to generate electricity. Over 95 per cent of Singapore’s electricity is now generated by natural gas.
How can Singapore achieve water sustainability?
Singapore has developed a new technique for recycling wastewater: a four-stage treatment process (conventional treatment, micro-filtration, reverse osmosis and UV treatment), branded NEWater. This water is drinkable, and is distributed to the city’s drinking water reservoirs, but most of it is utilised in industry.
Is Singapore water privatized?
This is a level that no other country can match at present. By comparison, in England and Wales, the only region in the world which has privatised its water more than a decade ago, the best level any of its private sector companies have managed to achieve is more than twice that of Singapore’s.
What is the difference between NEWater and desalinated water?
Desalinated water, which currently meets up to 30 per cent of water demand and will meet 30 per cent of future demand in 2060, is the most energy-intensive water source. NEWater, on the other hand, currently makes up 40 per cent of water demand, and meet up to 55 per cent of future demand in 2060.
Is NEWater energy efficient?
A demonstration study was carried out at Kranji NEWater Factory, where this technology was able to reduce membrane scaling and increase NEWater recovery rate to 90% with no impact on energy consumption.
Why is NEWater expensive?
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.
Is it necessary to use bottled water in Singapore?
Singapore’s tap water quality is well within the Singapore Environmental Public Health (Water Suitable for Drinking) (No. 2) Regulations 2019 and World Health Organisation (WHO) Guidelines for Drinking-water Quality. Our tap water is suitable for drinking directly from the tap without any further filtration.
Is bottled water really better?
Overall, both tap and bottled water are considered good ways to hydrate. However, tap water is generally a better option, as it’s just as safe as bottled water but costs considerably less and has a much lower environmental impact. Plus, with a reusable water bottle, tap water can be just as convenient as bottled.
How does Singapore get water?
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.
