I don't know if my local hellhole has a problem with fatbergs, but the lack of street cleaning due largely to the unwillingness of residents to move their cars once per month gives us a lot of
clogged drains.
Nor is Manila’s sewer system the only one with hardening arteries. London, Cardiff, Melbourne, New York and Denver are all tackling subterranean fatbergs. Many cities around the world are at daily risk of of suffering a municipal coronary. And flooded streets are just one possible outcome. Two years ago a fatberg in a main sewer in Bristol resulted in a discharge of raw sewage into the River Trym, killing hundreds of eels, sticklebacks and bullheads.
