News from London (... not so latest though !)
( TOURIST BROCHURE )
London relies on a 150-year-old sewer system built for a population less than half its current size . As a result , tens of millions of tonnes of raw sewage overflow the system each year and end up in the river Thames . We are building a 25km super sewer under the Thames to intercept those nasty spills and clean up our river . The project will also bring thousands of new jobs , as well as new public space , creating a better environment for Londoners .
