China $700 billion water diversion project benefits over 100 million people

[Han Patriot]

Increasing urbanization makes adopting such technologies feasible as it gets more cost efficient. Beijing for example is suitable to adopt new water technologies IMO, instead of diverting water resources from the South.

But of course I know it's still not cost efficient for the hundreds of million of people living in the countryside.

If you are Chinese by descent, you should realise Chinese are not stupid right? Do you know how many desalination plants we need to build to supply those cities?

2 water recycling plants in Singapore can produce 600 million cubic meters of clean water annually. How many such plants does Beijing needs?

新华社8月底的一篇报道指出，北京、天津等北方城市的人均水资源远远低于世界缺水警戒线，其中北京近10年来每年形成的水资源量平均只有21亿立方米，而年用水总量达36亿立方米，缺口达15亿立方米。

At the end of the day it's just about cost efficiency, and Chinese officials decided that it's cheaper to build huge diversions from the South to the North.

Singapore is much smaller than a Beijing‘s ’district, it's no pointless to compare Singapore with Beijing.

北京地下水位四年回升3.16米
2019年06月20日 10:20 来源：北京日报 记者 朱松梅

　　5月底，全市平原区地下水埋深平均为23.32米，与2015年同期相比，累计回升3.16米。

　　南水进京之前，本市地下水位曾经连续16年下降。2015年以来，本市多措并举，通过用好南水、压采地下水、河道补水，地下水进入了快速恢复期。

　　近八成平原区水位回升

　　全市885个地下水监测点数据显示，今年5月底，全市平原区地下水埋深平均为23.32米。与2015年同期相比，地下水位累计回升3.16米，地下水资源储量增加16.2亿立方米。

　　这样的回升，并不是偶然的、小规模的。“四年来，全市共有14个区地下水位上升。平原区地下水回升面积达4957.3平方公里，占全市平原区面积的78%。”市水务局相关负责人说。

　　数据显示，平谷区地下水位回升值最大，四年上升了9.23米。其次为门头沟区，回升值为8.5米。其余各区的回升值在0.3米到5.88米之间。

　　自1999年起，本市经历了连年干旱，再加上经济社会迅速发展，用水量急剧增加，不得不靠超采地下水以维持城市运行。因此，全市地下水位连续16年下降。

　　2014年底南水进京，是本市地下水止跌回升的转折。四年来，南水北调来水成为京城的供水主力，怀柔、平谷等应急水源地得以休养生息，去年，本市还在中心城区完成了近300眼自备井置换工作，相当于每天减采地下水8万立方米。

　　2015年，地下水位停止下降，2016年和2017年分别回升了0.52米、0.26米。

　　京郊的山涧泉眼复涌了

　　距延庆城区10公里，妫水河支流宝林寺河中，6孔泉眼在今年春天复涌了。

　　清浅河水里，几块石头间正咕嘟嘟冒出珍珠般晶莹的小泡泡，一群小蝌蚪围着泉眼游动。汩汩泉水汇成溪流，绵延流淌1.7公里。这样的景儿，让宝林寺村村民张怀恩恍然回到了30年前。“那时候，河里的泉眼可不稀奇，家家户户吃的都是河水、泉水。”张怀恩说。

　　进入新世纪，本市地下水一降再降。据统计，与1980年相比，本市地下水位在30年间下降了近20米，储量减少了近90亿立方米。连年下降的地下水位，使得京郊不少山涧干涸、泉眼停喷。

　　如今，随着地下水位的不断上升，在昌平的连山石村、延庆的艾官营村、怀柔的百泉山，都有泉眼恢复喷涌。

　　六条输水路径涵养地下水

　　今年5月，怀柔雁栖河两岸的居民发现，以往的涓涓细流在这个春天变作清澈宽阔的水面，最宽处超过10米，潺潺流水倒映着两岸绿树繁花，美景醉人。

　　清澈的河水来自京密引水渠，经雁栖闸顺流而下注入雁栖河，能有效补充怀柔应急水源地的地下水亏空。自2015年起，这样的补水就在陆续开展，目前已累计在该地区补水1.08亿立方米。眼下，水头已到雁栖分洪闸下游约5.8公里处，形成水面面积约0.42平方公里。

　　“地下水生态回补的路径总共有6条，主要通过向潮白河、雁栖河、北坞砂石坑、永定河、洳河、泃河等河道补水，河水下渗，能够补充地下水。”市水务局相关负责人说，有效促进了密怀顺水源地、西郊山前、永定河流域等严重超采区的水源涵养修复。

check beijings population n do the math...the water diversion is for 300 mil ppl

I'm talking about Beijing, not the entire North region.

And Beijing is lacking only 1.5 billion cubic meters of water. 6 of similar water recycling plants in Singapore can produce that much clean water.

my friend, check the distance between beijing and the sea. Next, there was already a plan to supply beijing with desal water. You are talking about beijing, BUT THIS WHOLE THREAD is TALKING ABOUT THE NSWT PROJECT. Get it my dear Singaporean Indian friend?

 

[Mista]

Singapore is much smaller than a Beijing‘s ’district, it's no pointless to compare Singapore with Beijing.

Exactly. If Singapore with 5 million people and a land area 20x smaller can produce 600 million cubic meters of clean water annually just from water recycling, why can't Beijing scale up and produce 2 billion cubic meters of clean water?

Hong Kong and Singapore are not water self reliant due to their small size and isolated environment, so they have to use drastic measures to secour water security, it's their life line, Beijing, like all big cities in the world, is not in that dire situation, Singapore's model is for small city states, not for big cities of big countries.

Singapore's water is supplied by Malaysia and Beijing's water was provided by China, there's big difference between them.

Indeed there's a geopolitical aspect to it; Singapore once threatened to invade Malaysia if they cut off our water supply.

But my point is, with increasing urbanization it becomes possible to leverage on water technologies. And Beijing, which is highly urbanized and wealthy, is suitable. Israel for example treats 90% of its sewage water.

Most importantly water recycling is virtually unlimited and climate-resistant. The only limit is plant capacity and cost efficiency, which I think will continue to improve as water technologies advance.
Huge water diversions aren't exactly cheap anyway, and it involves the relocation of thousands of families and unknown environmental impact. As a foreigner I don't know what's the impact as the water diversion goes largely unreported, so I'm just wondering if it's possible for water technologies to replace such mammoth engineering in the near future at least in the cities.

I was talking about desal, then you suddenly talk about recycling, I was talking about north south water transfer, then you suddenly talk about something else...you really change alot of topic. Do you have the figure of Beijing's water recycling? You need to understand that our budget not just being used by beijing, it's being used by 1.4 bil Chinese. Common sense okay. The way you talk is like an appu...it smells of curry...lol

 

[beijingwalker]

China's water policy is being managed well and in hands of very capable professional and experts, we don't need foreigner to teach us what we should do, we know our water issues way more than other peoples.

Nice try.

My original post, which you quoted, is focused on water recycling.

My figure of producing 600 million cubic meters of water annually in SG, which you quoted as well, has 'water recycling' written clearly.

It's you who can't read and now you're wiggling your way out. Continue your prata-flipping and obsession with Indians lmao.

I was trying to correct you because this thread is about NSWT IN CHINA, not recycling plant in beijing. It is not feasible to use the Singaporean model in China. Understand genius. Desal used in Sg is also not feasible because of cost concerns, and also the scale needed. And talking about recycling, please go check the amount of water recycled by Beijing alone. WE JUST DON'T DRINK RECYCLED PEE.

I was trying to correct you because this thread is about NSWT IN CHINA, not recycling plant in beijing.

And I'm talking about the feasibility of using water technologies in urban areas, as compared to water diversion. Is that not relevant? What's there to correct?

China's water policy is being managed well and in hands of very capable professional and experts, we don't need foreigner to teach us what we should do, we know our water issues way more than other peoples.

Why so defensive lol.

The purpose of creating a thread here is to generate discussion among foreigners, isn't it? Why else would you not create a discussion in Weibo or Zhihu?

Or is your intention bragging about mammoth infrastructures in China? Because it seems so, judging by your threads and posts here.

It's not bragging, it's the reality and no one denies it, the reason why all Chinese think you are an Indian is because you consistenly picks on China and do the nitpicking, in your eyes, nothing is right about China. Singapore is small city state, it can be as different as difference can be when comparing with huge continental size countries like China, try to compare Singapore with similar size countries could be more suitable, start with Vatican maybe.
