Elképesztő méretű szupercsatorna segíti az Egyesült Királyság vízhálózatának működését

London's existing sewerage network dates back to the second half of the 1800s. With the size of the population set to continue to swell, the need for the Ł4.3-billion ($5.6-billion) upgrade has become critical. The new 25-kilometre (15-mile) "super sewer" is 7.2 metres in diameter and snakes from west to east following the curves of the river. (Photo by Daniel LEAL / AFP)
