[Cob] Farming water bermuda style

> I was in Bermuda a little over a year ago, and found that they have only one real water source: rain. Each house has a slanted white roof with a chemical or something on it that purifies the water as it runs down the roof and into a tank. There are also large slanted "white roofs" at various locations on the island (not on a building, but in a small field) that are community owned, so that, in the case that people start to run out of water in their homes, they can get purified rain water from these public water collectors. Does anyone know anything about this, how it works, how it purifies the water?
