Is this a forewarning of reservoir in Johor Straits?

Within a short span of 4 months, Straits Times has TWICE published a letter to the forum page by readers suggesting a reservoir to be built between Pulau Ubin and Singapore, at the Johor Straits. Surely Straits Times is not forgetful in its old age despite PUB providing an official reply on the forum stating that it's not considering such a reservoir. However, is this a forewarning by our media of greater things at work? If this is an idea that's traversing the brilliant minds of our policy makers, I can only hope they perish that thought forever!

Create reservoir between Pulau Ubin and Singapore
Letter by Chew Wai Soon, Straits Times Forum
Aug 7, 2008

COME 2012, we will have to be more self-reliant for our water supply.

I propose Pulau Ubin be linked to mainland Singapore to create a huge reservoir.

On the eastern end of Pulau Ubin, a two-tier road can be built so the lower deck allows cyclists to cycle between Singapore and Pulau Ubin. The upper deck will be another route for vehicles to go to and from Malaysia. Jetties can jut out from both sides of the link - the reservoir side for smaller boats such as kayaks, sailing and racing boats, and water scooters, while bigger boats can dock on the other side. Bicycle rental kiosks, souvenir shops and so on can be built at the starting point of the link at the Singapore end. Further reclamation at the Singapore end will allow immigration offices and multistorey carparks to be built.

On the link at the western end of Pulau Ubin, bicycle rental kiosks, food centres and souvenir shops with solar-panelled roofs can be built for cyclists to cycle between Singapore and Pulau Ubin.

Pavilions can also be extended from both links into the reservoir for relaxation, photography and fishing.

Pulau Ubin can be promoted extensively as a venue for camping, mountain biking, adventure, trekking, hiking, jogging, horse riding and prawn fishing (to meet strong demand for youngsters to rough it out and enjoy nature).

The proposed reservoir will mean less land use elsewhere - some of the existing reservoirs can be redefined as collection centres for rainwater and Newater, and their water channelled into Pulau Ubin reservoir. The surrounding land can then be freed for other use, such as residential development to house a growing population.

Feedstock for Pulau Ubin reservoir can also be had from excess water from the smaller reservoirs, from rainwater and Newater to be collected from the northern and eastern parts of Singapore and from more Newater that could be generated.

Big water pipes connected to both links at Pulau Ubin would help to drain seawater between Pulau Ubin and the Causeway and provide a change of seawater according to the tides. Energy-generating turbines can be incorporated into these seawater pipes.

Coney Island can be reclaimed further to become part of the mainland and pavilions can be extended from Coney Island into the reservoir.

The damming of the water between Pulau Ubin and Singapore to become a huge reservoir promises many possibilities for development, for meeting future water needs and for recreation.

I urge the authorities to look into these great benefits on our doorstep.

What's wrong with an Ubin-Tekong reservoir?

On April 18, 2008, Syu Ying Kwok wrote in to Straits Times Forum suggesting that after the Marine Barrage, to make the biggest reservoir ever, we should connect Ubin, Tekong and Singapore together to form the biggest reservoir ever. In fact, Syu esq. wrote that "If we can do this, the volume of this new body of water will be at least twice that of MacRitchie, Lower Peirce, Seletar and the new Marina reservoirs combined."

Sure, as we all know, for Singapore to be fully self-sustainable in water supply is one of our most important national prerogative. In fact, somebody commented on ST Online Forum that "it has been long overdue"! However, are we becoming myopic in our hunt for water?


Do you know where we are talking about? Check out the map. The blue placemarker at the far most left of the map is Sembawang Shipyard. Across is Pasir Gudang. The blue boundary indicates possible ubin-tekong reservoir location. within the boundary is Chek Jawa

Here are some reasons why having a Ubin-Tekong reservoir is ecologically, politically and logically problematic:

1) Humans can only drink fresh water. The idea of reservoirs is to dam up rivers, which is a source of fresh water, so that we can pool this fresh water together to become a constant reservoir of fresh water supply. The marina barrage was already a problem because it is at an estuary which we have never dammed up before. This means they have to flush out all the sea water from the area before we can slowly let fresh water from further upstream (from Pierce Reservoir) fill up the reservoir. Now if we dam up the sea, where will we get this supply of fresh water to fill up this mega swimming pool? Malaysia?

2) In the first place, would Malaysia sit back and let us build this mega swimming pool at their door step? When the Pedra Branca dispute is not even settled (results out middle or end of May 08), mere suggestions of such a mega infringement of international boundaries is simply unimaginable. Let's not forget the quarrel over Tekong's reclamation.

3) Why would they be upset you say? Well, you do now that the area between Ubin, Tekong and Singapore happens to be one of the busiest shipping lanes in the world! Ships travel between Pasir Gudang, Sembawang Shipyard and the world. Even if we ignore our neighbors, surely you would not want to kill one of our biggest industry at Sembawang would you? Previously when we wanted to connect Singapore to Ubin and Tekong via MRT line, there was already a big hoohaa. If you look at the google map above, you'll realize that for a ship to want to travel to any of the northern ports and shipyards in Singapore, you'll have to travel through the place where the supposed Ubin-Tekong Reservoir is. We have to keep to our side of the international boundary after all!

4) Being a shipping lane, that area is also potentially polluted and constantly dredged. If we think that technology can overcome everything like the Marina Barrage then alright. But how much do you think this venture will cost? If we look at the cost benefit analysis, it'll probably not be justifiable. As a tax payer, I'm not willing to have my money being spent on building another swimming pool which may start a war when there are now a lot more other technologies out there to provide water in a more intelligent way. Yes, we are all about technology but as a Professor of mine said, it is no longer at technology's forefront to build reservoirs to collect water. Desalinization and reverse osmosis is just some of the examples of newer technologies but even those have been circulated for a while now. Besides, with potential sea level rise, a swimming pool out in the sea risk submergence or infiltration of salt water. Once salt water infiltrates the reservoir, do we have to flush out the fresh water and start over?

5) While most people may not care what happens ecologically but let me highlight a few items. If we are to reclaim Ubin Tekong and Singapore, then it's goodbye chek jawa. Goodbye Sekudu. Goodbye dugongs. Goodbye coral reefs. Goodbye mangroves. If that doesn't mean anything to you? Think seafood. We always see fishers off the waters of Ubin because there are fantastic amount of seafood there. Goodbye fish farms off Ubin. We'll now have even lower self-reliance on seafood supply and have to further import from others. Is it a worthy trade off?

I hope it becomes more apparent now that there are far more issues than benefits to building such a Ubin-Tekong reservoir. Honestly there are more reasons that I did not mention. Although we are a country that prides ourselves in our ability to overcome anything with technology, you could not begin to imagine what a diplomatic and economic nightmare it would be to create such a monster out in the most sensitive area out in our international boundary.

Sincerely, I hope that Singaporeans will make more informed decisions before speaking out in nationally published newspaper that is also read by many of our neighbors in Malaysia and beyond. How come we don't get positive letters in the Forum pages expounding the beauty of our northern islands instead?! Not news worthy enough?

update @ 12.58pm (18 Apr)
Finally somebody who thought things through posted a comment on ST Online Forum citing Malaysia sensitivities in the Straits of Johor.

update @ 2.26pm (18 Apr)
Ria at Wildfilms talks about the amazing northern shores of Singapore and what individuals like us should do when faced with such dam ideas.

update @ 19 Apr
Ivan K. has submitted a reply to Straits Times Forum. Hopefully it gets published.
