Chinese New Year has arrived and as London celebrates the Year of the Dog with the biggest Chinese New Year celebrations outside of Asia, my thoughts turned to this city's longstanding love affair with man's best friend, the dog. There's a lot of puppy love in the Great British capital - a phenomenal 200,000 dogs and counting call London home.  That's almost twice the size of the population of Reykjavik! 

London’s five billion pound Super Sewer is now fully connected and promises a cleaner, healthier River Thames. The 150-year-old sewer network has struggled to cope with the twin challenges of an increase in the population it serves in the capital (from four million people when it was built to over nine million today) together with climate change. With rainfall overwhelming the system, it sometimes discharges into the Thames. With the Super Sewer fully connected, 95% of those spills are stopped.
