I walked from Soi 11 to Esplanade today so the photos are somewhere roughly 1/3 of the way there. You can see where the water level is.
As you can see there’s some sort of measuring stick there. I don’t know anything else about it.
Looking into the sewer system, you can see how far down the water is.
There’s a large pump installed here. I’m not entirely sure which direction it’s going and it’s purpose. Anything would be a guess.
More as things develop.
