Water for Mexico

  • The cenote, or natural sinkhole, stretches 114ft long and is up to 65ft deep
  • It is capped by 13ft of limestone which is gradually being washed away
  • Experts have found it is connected to other caverns and lakes in the area
  • They say it may have had deep religious significance to the Mayan culture

So there is a network of tunnels under Mexico. That are filled by fresh water filtered through limestone. But in places the sea has come in, and turned the water bracish. No problem – we need to clean all organic matter from it anyway.
We have a 10W vacuum pump sited above the underwater river. This sucks up water. And as it reaches 3m above the river, it boils – at 3oC. So it loses all salts and contaminants, Nature has brough the water 100s of km – for free.
We distribute the fresh water in a 3kn radius – and nature brings us more free water. In time the water will percolate down – and re-entre the river anyway.

But now we have a lush arable area. Which we repeat every 6km.
