To highlight a new type of water purification system, a restaurant in Kuurne, Belgium, has started serving its customers free drinking water recycled from its sinks and toilets.
The water served at the Gust’eaux restaurant in Kuurne these days is the same as any other potable water – it has no smell, no taste, no color – so it’s impossible to tell that it’s source is actually the restaurant’s toilets. By using a complex, five-step purification system, Gust’eaux is able to turn its sewage into a water so pure that it has to be enriched with minerals before being served to clients.
