Biggest pool in the world

I seem to be on a swimming pool theme… I just read about the biggest pool in the world. It is a saltwater pool in Chile that is truly monumental:

  • Almost 1km long
  • 35m deep at the deep end
  • It took 5 years to build
  • Building cost was almost $2 billion and maintenance is about $4million per year!
  • The filtered and recycled seawater is so clear that you can see the bottom, even at the deep end

It is pretty amazing. Here is a link to a short report on the pool.
