A glob of fat the size of a school bus was stuck in the London sewers. The 15-ton ‘fatberg‘ formed when waste food fat congealed around discarded wet wipes in the main drains under London Road in Kingston, Surrey. The blockage was removed by engineers before raw sewage started spurting out of neighborhood manholes. Fatberg-damaged sewer pipes will take six weeks to repair.
Lady Bird, a 400-foot-long, $30 million, 1,300-ton German-made tunnel boring machine, will soon be carving miles of 22-foot-wide tunnel 100 feet below the Potomac riverbed. It’s part of DC Water’s Clean Rivers Project, the second-largest civil engineering project in DC history (only Metrorail is bigger). When completed in 2025, the $2.6 billion EPA-funded dig will keep raw sewage from flowing into the Potomac and Anacostia when it rains hard. That’s what happens now (it’s called CSO, “Combined Sewer Overflow”).
Lady Bird will be underground and out of sight, but you can follow her on her own Twitter account.
