Yesterday i have updated the main hole closure underneath.

However, today, after thoroughly recheck, the main hole underneath has two humes round pipes to connect the inlet and outlet to main drainage underneath the road.

However, the face of outlet pipes were below the drain water level. That's why we can't see it. Meaning, technically, if the water rise, can the rain water from the other side pressure into the pipes?

We will update when the actual time is right and when the heavy rain downpour. Whether this method is applicable technically.

If it's not workable, LRT is just doing a nonsense process.
