Grease and wipes wreaking havoc on SF sewer system
After a 15-ton block of fat and baby wipes was recently discovered clogging up a sewer near London, sanitation officials in San Francisco on Wednesday were warning residents to think twice about what they flush down their toilets and dump down their drains.
London sanitation officials said the massive 30,000 pound lump of lard was the largest such blob they have ever seen and could take up to six weeks to clear it out.
San Francisco utility workers said the introduction of so-called flushable wipes and animal fat have created a huge problem for the city that ends up hurting the sewer system.
As it turns out, too much grease from fish and chips and other fried foods isn't just bad for your health.
"This is like a clogged artery," said SFPUC Assistant General Manager Tommy Moala. "I would say this is a sewer heart attack if you keep adding grease."
San Francisco sewer workers are waging war against grease buildup in 1,000 miles of pipe.
