LONDON–Every day beneath the streets of London, sewer technicians are fighting a grim war against giant fatbergs which clog the system and threaten to regurgitate putrid waste back into people’s homes. The problem gets worse at Christmas, when two extra Olympic-sized swimming pools of turkey fat are poured down Londoners’ sinks. Most residents are unaware that their actions help create fatbergs �X the nickname for stinking boulders of cooking fat, congealed with everything from wet wipes to sanitary towels and condoms, which block the sewers a few meters below their dining tables. The problem of congealed fat clogging up Thames Water’s 69,000 kilometers of sewers in London and southeast England is getting worse. But in the heart of central London, a few hundred meters from Downing Street and Trafalgar Square, the fatberg fightback is on. Vile, Eggy Stench The sewers �X a confined, pitch-black underworld crawling with flies and worms where staff walk through a deep seam of rotting fat and excrement �X are many people’s idea of hell. But this is where Vince Minney, a supervisor from the Thames Water authority, has made his living for the past 24 years. Wearing waders and a white protective suit, Minney, 54, climbs into a tiny manhole in the road and descends seven meters on a fixed ladder into the putrid bowels of the city. ��The fat situation is definitely getting worse. It’s building up in certain sewers it never did before,�� he told AFP, standing waist-deep in rancid gunk where the Regent Street and Victoria sewers merge. The flow of human waste in the sewers is not the problem, he said �X it’s the heavy ��blanket�� of congealed fat stuck on top. ��It’s about the nastiest stuff you can get. The diarrhea stuff is a pleasure compared to this,�� he added, tapping a spade on the thick fat layer engulfing his thighs. Minney and his team break up the fatbergs using spades or high-pressure water jets. Fungi grow on the crust, which looks like solidified vomit. Walking through it leaves a wake like an icebreaker ship. Each spade chop unleashes the effluent beneath, releasing the revolting stench of hydrogen sulfide which can cling to a worker’s body for up to two weeks. ��It’s very, very sickly. It just smells awful,�� added Tim Henderson, 39, a ��flusher�� or trunk sewer technician of seven years’ experience. ��Like a cross between a sweaty, cheesy-type smell, mixed with sewage.�� Getting splashed with anything in the sewers is no fun, either. ��It’s not nice in your face,�� said Minney. ��I’ve had some good splatterings before. Sometimes the flies go in your mouth. Spit ’em out quick,�� he chuckled. City Beneath a City
A good sense of humor and plenty of dedication is required to work in the sewers, which date back to the 1860s.
