Lid of manhole

I wrote that TEN likes OSUI smell last week.



I saw some lids of manhole.

There are any kind of lid.



It is written "あめ" at this lid.
I think that "あめ" is rain water.



What's "うすい" mean?
I think that "うすい" is also rain water.


I like this lid very much!
This lid is artistic.
