Anne Gracie found this interesting article from Atlas Obscura which describes how the island of Bermuda has managed to survive and flourish with absolutely NO natural sources of fresh water: no streams, lakes or rivers. Since the Mayhem Consultant and I spent a brief honeymoon there, Anne suggested that I might revise the original travel blog with an emphasis on how how the island has managed with no natural sources of drinking water.
Except one: Rainwater.
On our previous visit, our guide pointed out the white limestone roofs of all the buildings and explained that they caught rainwater and channeled it into cisterns under the houses. At the time, that was just one more interesting fact about the island, but the AtlasObscura article explains a good deal more about this brilliant but simple architectural feature that made it possible to support one of the greatest population densities in the world. (About 65,000 people on a mere 21 square miles of land pieced together from 181 islets.)
All roofs on the island are required to be made of limestone and designed for rain catch. The island is actually made of limestone so when erecting a new building, the stone taken from the ground can be used for the inch thick roofs. And those roof are TOUGH. Some island roofs have lasted since the 17th century.
