New York, for example, was one of the first major cities to build a large sewer system, starting construction in 1849. Many of those pipes — constructed of hand-laid brick and ceramic tiles — are still used. Today, the city’s 7,400 miles of sewer pipes operate almost entirely by gravity, unlike in other cities that use large pumps.
New York City’s 14 wastewater treatment plants, which handle 1.3 billion gallons of wastewater a day, have been flooded with thousands of pickles (after a factory dumped its stock), vast flows of discarded chicken heads and large pieces of lumber.
When a toilet flushes in the West Village in Manhattan, the waste runs north six miles through gradually descending pipes to a plant at 137th Street, where it is mixed with so-called biological digesters that consume dangerous pathogens. The wastewater is then mixed with chlorine and sent into the Hudson River.

The engineers who run this system have a miserable job.
“I went to Hawaii with my wife, and the whole time I was flipping to the Weather Channel, seeing if it was raining in New York,” [Bob Connaughton, plant engineer,] said.
