About Famous Pools

I was browsing the internet yesterday and I stumbled upon this article about some of the most famous swimming pools around the world. Those in the list are quite amazing.

There are these really huge pools in Japan and in Chile, and this really deep one in Belgium, and a whole bunch of other amazing pools.

Seeing those made me wonder what kind of maintenance work they do on those pools. Our small backyard pool is already difficult enough, how much more would it be for those pools. Are there even pool covers for sale that can accommodate those?

That is if they still do cover them. Just thinking about it already drains my energy.
