Tap 4 - Desalinated Water

Singapore is surrounded by sea. Desalinating salt water can help to increase Singapore's water supply.
Discuss and evaluate this strategy.

  1. Now do what? Talk about the geography thing.

  2. must be serious... :)

    using desalinated water is much cheaper than using NEWater, because of the hceaper membrane prices :)

  3. Desalinated water is Singapore's 4th National tap.

  4. Like its predecessor NEWater, desalinated water is the result of PUB's continued investments in water technologies and research. Recent advancements in technology and cheaper membrane prices have made desalinated water another viable source of water supply for Singapore.

  9. there is an opening of the Singspring Desalination Plant at Tuas...

    want to go visit???... lol... joking :P

  10. who the hell is Mary Alexander Lim?

  11. ya lah... anonymous. who r u???

  12. called Singspring..funny name. anyway,it is the first public-private patnership programme..
    able to provide 30 million gallons of water a day(130000 cubic metres)

  13. water is cool! like me

    ReplyDelete
  14. what the hell are we supposed to do

    ReplyDelete
  15. but using desalinated water needs a lot of processes, unless we are able to drink salty water... lol...

    ReplyDelete
  16. quite a lot for a day...right? if yes, shouldn it be an advantage?

  17. In September 2005, Singapore turned on its fourth National Tap, with the opening of the SingSpring Desalination Plant in Tuas. The SingSpring desalination plant was PUB’s first public-private partnership (PPP) project. This plant can produce 30 million gallons of water a day (136, 000 cubic meters) and is one of the region’s largest seawater reverse-osmosis plants.

    Like its predecessor NEWater, desalinated water is the result of PUB's continued investments in water technologies and research. Recent advancements in technology and cheaper membrane prices have made desalinated water another viable source of water supply for Singapore.

    At the SingSpring plant, sea water goes through a pre-treatment process where suspended particles are removed. In the second stage, the water undergoes reverse osmosis (RO). This is the same technology used in the production of NEWater. The water produced is very pure and is remineralised in the third stage. After treatment, desalinated water is blended with treated water before it is supplied to homes and industries in the western part of Singapore.

  18. whiteken? water is not cool. It is just clean, healthy for drinking, swimming, and ya, let's better answer the question. Miss Chin Angry le.

  20. yeah isnt that whole thing the info about the desalination

    ReplyDelete
  21. I Don't know. Still got what advantages??? Cause i basically can't think of one. But what type of water are we using?

    ReplyDelete
  22. i think desalination is more convenient..isn singpapore surrounded by nth but water?

    ReplyDelete
  23. Gideon, we are supposed to talk here about wad u noe for destilation.

  25. singapore carries out the desalination of sea water supply.A desalination plant was started in tuas in 2005.although the cost of building and operating this plant is high, it will supply up to 10%of the nation's demand.this plant uses the reverse osomosis method, which is to that used in the production of reclaimed water

  26. desalinated water is one of the largest seawater reverse osmosis inn the region and it is the result in PUB's continued investment in tech. and research.

    We are using seawater right?

    ReplyDelete
  27. disadvantage is high cost

    ReplyDelete
  28. I think we can bath using saltwater.

  29. Increased water conservation and water use efficiency remain the most cost effective priority for supplying water.[26] While comparing ocean water desalination to waste water reclamation for drinking water shows desalination as the first option, using reclamation for irrigation and industrial use provides multiple benefits.[27] Urban runoff and storm water capture also provide multiple benefits in treating, restoring and recharging groundwater.[28] An emerging alternative to desalinization in the State of California and other areas in the American southwest is the commercial importation of bulk water either by very large crude carriers converted to water carriers or pipelines. The idea is presently politically unpopular in Canada where governments have been scrambling to impose trade barriers to bulk water exports as a result of a claim filed in 1999 under Chapter 11 of the North American Free Trade Agreement (NAFTA) by Sun Belt Water Inc. a company established in 1990 in Santa Barbara, California, to address pressing local needs due to a severe drought in that area. Sun Belt maintains a web site where documents relating to the dispute are posted online at Company website

  30. high cost? But it is MUUUCHHHHH cheaper than NEWater(the membranes damn ex)

    ReplyDelete
  31. By using destilation, we can sort of clean the water, remove salt from it and to purify it. So that the water is fit for drinking.

    ReplyDelete
  32. but need to heat up the water to a damn hight temperature

    ReplyDelete
  33. so what are the differences between using desalinated water and NEWAter?

    ReplyDelete
  34. = =
    Saltwater(Or you mean seawater) may contain bacterias and other substances that are harmful to the body.

    And yeah, the cost for desalination is really high.

    ReplyDelete
  35. ANyway, now sea level rising..more water to desalinate=D

    ReplyDelete
  36. oo. Now sea level rising that means there will be more desalinated water, which means MORE WATER to USE!!! But cannot waste water.

    By the way, which type of water you all like? i prefer desalinated water, because drinking NEWater like very weird. Very distilled.
