More than 211 million gallons of sewage has spilled into Fort Lauderdale's waterways

More than 211 gallons of sewage has spilled into the waterways and streets of Fort Lauderdale, Florida, killing fish, seeping into houses and prompting the city's mayor to plead for state and federal assistance.

The problems began in December, when aging sewer pipes in the beachside city broke six times, releasing 126.9 million gallons of toxic sewage — one of South Florida's biggest spills ever, according to the South Florida Sun-Sentinel. The waste poured into streets in three neighborhoods of the popular tourist destination, plus the Tarpon River and Himmarshee Canal, the paper reported.

Then, over the course of 10 days at the end of January and beginning of February, another 79.3 million gallons spilled, this time into George English Lake, the Sun-Sentinel said. Another 5.4 million gallons flooded streets near George English Park, across from a popular mall.

“All the fish are dead there,” Fort Lauderdale fisherman Jeff Maggio told the Sun-Sentinel on Sunday. “Everything’s just gone. Crabs, oysters, barnacles and plankton. Crews have been out there picking up hundreds of fish out of the water so it doesn’t look like holy hell. Manatees are swimming in that poison.”

Fort Lauderdale's sewage system was built more than a half-century ago. Leaks beginning in 2014 led to a state mandate requiring the city to start improvements immediately and fix the system by 2026.

The city is racing to clean up the 211.6 million gallons of toxic sewage — enough to fill 320 Olympic-sized pools. But Mayor Dean Trantalis fears the efforts will not suffice and plans to discuss a request for federal and state aid overhauling the sewage system at a city commission meeting on Tuesday.

"There's no way anyone could have taken care of every single aspect overnight. It's going to take years to do it," Trantalis told NBC News.

The sewage leaks come amid another crisis hitting Fort Lauderdale's pipes: In recent weeks, a series of water main breaks have forced residents to boil their tap water before using it.
