With the search for new water sources that are reaching their limits, Singapore is turning to another key area of research to ensure that it derives more value from every drop of water. clean water that it produces.
million dollars that went into the research and development of water here went into the water treatment processes less electricity consumption. "19659002" We push the frontier of water technology to meet the urgent challenges Harry Seah, deputy general manager for future systems and technologies at the National Water Agency PUB, said Wednesday that
Singapore is becoming increasingly dependent on its two weather-resistant water sources – desalination and reuse of water. "The challenge is to ensure that technological advances continue to keep pace with the increasing demand for water so that these sources remain viable," he added.
million. Seah gave the media an update on Singapore's water research for a global water conference, Singapore's International Water Week, in Marina Bay Sands next week
. its reservoirs or the Johor River in Malaysia to meet its water needs.
A new "faucet" was commissioned in 2002 with the launch of recovered wastewater, or Newater, and in 2005, the first desalination plant in Tuas. 19659002] Today, these two faucets can satisfy up to 70 percent of Singapore's demand for 430 million gallons a day – the equivalent of 774 Olympic-size swimming pools. The two faucets are expected to meet up to 85% of future water demand by 2060. The demand for water is expected to double by then
But these two methods of treating water Water requires a lot of energy.
It takes 17 times more electricity than to treat rainwater to produce water by desalination or treatment of wastewater. The latter also produces sludge, which is finally buried.
PUB said that future demand with today's technology will see its electricity needs increase four times to 4,000 gigawatt hours (GWh) per year, with generated sludge doubling to 600,000 tons According to the PUB Singapore's long-term goal is to meet the demand for water by 2060 without going beyond the current amount of energy used and sludge produced. While Singapore is not constrained by energy as by water and land, it is still in its interest to maintain this low requirement to save on costs and fulfill its international climate commitment for reduce its carbon footprint, said Mr. Seah.
Assistant Professor Winston Chow of the Geography Department of the National University of Singapore said that if new "taps", such as underground water extraction, can be explored further, Singapore has succeeded in
"It is therefore wiser to invest in making these faucets more efficient and less expensive for domestic and commercial water users here."
Asit Biswas, guest expert on Water, visiting professor The School of Public Policy Lee Kuan Yew and winner of the Stockholm Water Prize have warned that demand management should be an essential element to guarantee the future security of water in Singapore
"We have reached a plateau in what technology can do to increase water supply." Other breakthroughs are likely to be incremental rather than transformational, he said. Professor Biswas
