The wonderful Christmas lights in Central London are coming down, and red lanterns are beginning to appear around Soho and in particular Chinatown. This is part of the celebration for Chinese New Year which is also known as the Spring Festival. This year it falls on the 28th January, the first day of spring in the lunisolar calendar.

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.
