Solid Gold
Although sewers are designed to collect waste, not everything that ends up there is worthless. In Japan, for example, workers at a treatment facility received 5 million yen in gold in 2009. They were sifting through sludge when they discovered the precious metal. They were able to use the metal because of the large number of precision equipment manufacturers in the area. They discovered 1,890 grams of gold per ton of garbage!
Luxury Watches
In fact, there is more luck in the sewers than we are aware of. In England, a drain technician named Aaron Large discovered four luxury watches in the drains in 2012. They weren’t ordinary timepieces. They included a £21,000 Rolex Oyster Perpetual Cosmograph in 18-carat gold, as well as another Rolex and two other high-end pieces that he discovered a few days later. The owner of one watch was eventually found, but the other three were unfortunately faked. Despite this, Aaron received a bonus from his boss for his efforts.
