#2 Singapore has been well aware of this problem brewing but their time table is too slow to convert the Singapore river into a reservoir. Also, when I was there over a month ago the river looked too polluted to make a safe reservoir with a lot of street sewers draining directly into it. That water needs to be redirected and cleaned first and the mud needs to have heavy metals and the like cleaned out. They should look at two US efforts. The first Deep Tunnel in Chicago. The second the cleaning up of many badly polluted mid-western rivers.
