You see here is the thing about large scale boreholes....They cause cracks in your house.They are extending pipelines from nooitgedacht scheme .
Drilling multiple bore holes .
There is a desalination plant in progress/ about to be built .
Some of these won't be completed before year end when day 0 is most probably hitting us.
You see the water is pressurised in well an underground lake. Suck that up and well there is nothing to hold the landmass up too, so it either collapses (causing a sinkhole) or well it sinks.
So take for example Jakarta. Jakarta as a city is sinking by wait for it 20cm a year into the ocean, nope its not global warming, they are sucking all the fresh water by masses of boreholes from underground. Thus the land is slowly sinking to fill up the gap removed by the fresh water.
Same happened in Tokyo, but well the Japanese noticed it and all boreholes stopped almost immediately. And the Japanese figured out other ways to get to fresh water.
However it doesnt make a difference in the Western Cape...as all the people from the Eastern Cape has already moved here...and we have dams filled to the brim.
