PUB water plan reveals 7 to 9 milllion population in 2060!

  w

  From 2002 to 2008,  Singapore  total population increased by 16% (4.14 million to 4.84 million),GDP growth of 62% (S $ 1,582 million to 2,576 million Current Market Prices).
  
  However, the sale of potable water is almost the same

  (daily 1,250,000, vs 1,260,000 cubic meters! ) !
  

   

  
  The PUB press release is just like a encrypted message.
  In the recent one issued on the first day of SIWW, it said, among other things,
  hh

   As the population and economy continues to grow, PUB expects the water demand to double in the next 50 years, with about 70% of the demand coming from the non-domestic sector, and domestic consumption making up the other 30%.
  
  By 2060, Singapore plans to triple the current NEWater capacity so that NEWater can meet 50% of its future water demand. There are also plans to ramp up desalination capacity by almost 10 times so that desalinated water will meet at least 30% of its water demand in the long term.

  www.pub.gov.sg/mpublications/Pages/PressReleases.aspx

  28-Jun-2010Long-term water plans released in new PUB publication today

  Desalination target increases by 10 times reveal the secret

  1.1 Assume desalinated water will meet  30% of its water demand in the long term

  the current desalination capacity is 1,360,000 m3.

  Then in 2060, SG water demand @@is 1,360,000 m3 / 0.30= 4,500,000 m3.

  In 2060,Domestic consumption 30%=1,350,000 m3 per day

  Currently,domestics water is 760,000 m3 per day/ 155 liters per day per capita,=4.9 million population.( pl read Key Environmental Statistics I list below for figures)

  Therefore, if my assumption is correct, then in 2060,

  population would be 1,350,000 m3/ 147 liters per day per capita%%

  =9,200,000 !

  %%( domestic water consumption 147 liters per day per capita is PUB 's target in 2020)

   

  Ok u will say what if meet 35%.

  1.2 Assume desalinated water will meet  35% of its water demand in the long term

  Then in 2060, SG water demand @@is 1,360,000 m3 / 0.35= 3,900,000 m3.

  In 2060,Domestic 30%=1,170,000 m3 per day

   

   

  population would be 1,170,000 m3/ 147 liters per day per capita%%

  =7,950,000 !

  1.3 Assume desalinated water will meet  40% of its water demand in the long term

  Then in 2060, SG water demand @@is 1,360,000 m3 / 0.40= 3,400,000 m3.

  In 2060,Domestic 30%=1,020,000 m3 per day

   

   

  population would be 1,020,000 m3/ 147 liters per day per capita%%

  =6,930,000 !

   

   

   

  @@ water demand,In my view there are two types,

  http://app.mewr.gov.sg/web/Contents/Contents.aspx?ContId=682

  1. One is the total sale volumes of all types of water, and another type is just the sale of potable water.I think when PUB say "PUB expects the water demand to double in the next 50 years,",PUB refer to type 2,ie PUB refer only to potable water.
  

  Type 1--all types of waters ie

  A. potable water-- Domestic and - Non-domestic

  B. NEWater

  C. Industrial water

  In the past 2 decades, Singapore population has been increasing 100,000 a year!

  So, it is not a big deal to increase 2 to 4 million in 50 years!

  The URA or MND 's future 6.5 million population is labelled as panning perimeter  .

  But it is SG gov practice of under stated target!

  Nvm LKY critized 6.5 million is too much. Who cares his casual comment?

  Now 3.5 population oredi so crowded..... Imagine SG being 2 or 2.5 X more crowded ......... with Bengalas, Ahbuneh neh and your Ah Tiongs.....................

  i probably won't be around by 2060 anyways. So all the best to you survivors!

  are you staying in North Pole or are u still living in mid 1990'?

  Today, SG total population abt 5 million,consisits of S citizens 3.3 m, PR abt 530,000

  and abt foreigners 1.25 million!

  zao bao mentioned abt 6.9 millions and water increase from currently 380 mgd--milion gallon per day(1,720,000 m3) to 760 mgd(3,458,000 m3)!

  1 gallon [UK] = 4.546 09 liter

  到了2060年，当人�增加到650万至690万时，我国用水需求将从目�的�天3亿8000万加仑增加一�，达�天7亿6000万加仑。

  2. But total sales of all water is 561 million m3 in 2009 and 1,530,000 m3 per day.

  so, where does 1,720,000 m3 come from?

  various sources of water

  all in %......NEWater(*)....desalination........local catchment & imported water

  2010..........30....................10.....................60

  2020..........40....................25.....................35

  2060..........50.....................30.....................20

   

  * *= % of NEWater in potable water.

  it will be intersted to note that in around 2002, there was official data that local catchment provided half of SG water demand. u can rtead from my old threads in Singapore water.

   

  2. Pl dunt litter. All rubbish go to catchments which will lead to reservoirs!

  Variable Salinity Plant (VSP) will treat mixture of rain water and blackish water from seas in one machine  into potable water. This technology is in later stage of development and will increase catchment to 90% of SG land!

  1.HDB areas are planned to have 534,000 more residentials units .This refer to land under management of HDB only!(include HDB and private units) HDB is one of land agency of SG gov!

  www.hdb.gov.sg/fi10/fi10221p.nsf/0/d4a0f107613b79944825766200236310/$file/Key Statistics.pdf

  HDB annual report 2008/2009,as at 31.03.2009, page 8,Town Developments!

  current dwellings units 884,000 , projected ultimate 1,418,000 units

  ie ,planned to have 534,000 more residentials units!(include HDB and private units)

  Cheers1

   

   

  2. PUB projection of 6 million is very low!

  wow--3,000,000 m3 or 3 m m3 by 2060!

  This means the PUB's projected population would be 3,000,000m3 x 0.3=900,000 m3,then divided by 147 liter

  6 million population!what a conservative projection!

  I guess there will be 7.5 to 8 million population by 2030!

  %%( domestic water consumption 147 liters per day per capita is PUB 's target in 2020)

   

  By then, the nation's demand for water will be double what it is now as a result of a growing population and industrial activity. PUB projects the country will need about 3 billion litres a day by 2060, split between domestic use and industrial use in a 30-70 proportion.

  Thats like double now. And we are bloody hell gonna be like Hong Kong.

  That makes me wonder, where the hell will that amount of people come from? Overseas?

  Whats the percentage of locals is to foreigners gonna be like?

  I see food shortage problems, hospital patient intake problems etc. etc.

  Mind you!
  
  Singapore is more crowded to begin with. We are ranked the 3rd most densely populated places in the world.
  
  Hong Kong ranks number 4th.
  
  Singapore's 7023 persons per square km.
  Hong Kong's only 6349 persons per square km.

  pl do not just copy and paste.

  This ranking just refer to all land ,ie gross land,HK has plenty of mountains and lot of lands still in private hands,while now, SG gov own 90 % of all SG lands!

  A more meaningful comparsions would be build up areas.

  Density of Singapore HDB is only 20 % of Hong kong public housing!

  A. Density in HK Residential areas
  Private Residential  3.6 million  2,500 ha ,ie 1,440 persons per ha (note 1 and 2 )
  Public Residential  3.3 million 1,600 ha,  Includes HOS/PSPS ($$ see below )and temporary housing area.ie 2,062 persons per ha
  Rural Settlement 3,400 ha Includes village housing and temporary structures

   

  Private Residential=Residential land developed by private
  developers (except village houses, HOS/PSPS
  and temporary housing area).

  $$ HOS= public housing for sale, like SG HDB ,in HK, majority of public housing is for rental .

  PSPS=like SG DBSS HDB

   

  B .Singapore is much better

  pop. on HDB estates(HDB flats only) 3,020,000 / 7,232 ha= 417 persons per ha!

  Yes, PUB can, But can SG afford set aside much more land for drainage system?

  Suppose SG allow for a mean rain fall plus 100 % allowance, we need a 2 meter

  diameter piple to discharge the rainfall. if we allow a once in 50 years rainfall,

  (like the Orchard rd one, 18 days of June(30 days x 60%) rainfall poured in 3 hours),

  How big is the pipe enough to discharge the rainfall? 5 meter diameter?

  3 meter more time very long distances is no joke!

  the unexpected blockage is the main problem.
