Answer:
Street sweeping is one of those vital municipal functions that affects everyone in the city, even though we know very little about it. Perhaps that's ignorance by choice. In case it isn't, we asked Douglas Marsiglia, chief of cleaning operations for the New York City Department of Sanitation, to give readers some insight into the process. And what better time to do so than the fall?
"A lot of people don't realize what a great service it is," Marsiglia says. "Especially this time of year — you've got all the leaves come down. That stuff would just be sitting in the street."
New York City street sweepers cover 6,000 miles a day at 8 miles per hour, enough to crawl across the country and back. At 7:30 in the morning the sweepers are working the metered parking areas. By 9 a.m., they've moved on to residential streets. Those get swept on alternate sides once or twice a week, with a supervisor ticketing cars that haven't cleared the curb. (A few districts, like Queens 10, don't get swept at all, says Marsiglia.)
The mechanical sweeper itself is a complex piece of equipment. Drivers first complete a training course at Floyd Bennett Field then work with a qualified pro before they're ready to go out on their own. They not only have to maneuver the unwieldy vehicle effectively, but clean all the inner parts at day's end, too. That maintenance is essential, says Marsiglia, because sweeping the whole city without mechanical brooms would be impossible.
"There's no way we could do this manually," he says. "We have to have this piece of equipment working and we have to make sure it's maintained properly, so it's always there when we need it."
There are some 450 mechanical sweepers in the city. To some people, they just look like they're pushing stuff aside.
They actually pick up the litter. They pick up any kind of small debris. They pick up dirt and dust — anything that's in their path.
They have what they call "gutter brooms." They sweep it to the middle, in between the broom. The broom runs it over. Then there's a pick-up broom that puts it onto like an escalator function, which we call "flights," which bring it up and deposit it into a hopper area of the broom. When the broom gets loaded it's very efficiently dumped into the back of a collection truck.
Meanwhile they spray water?
They have a water spray system that shoots the water off to the street, right in front of where the broom's going to pick up. It holds the dust down; it's also easier to pick up something that's semi-wet. It makes it easier for the [gutter] brooms to push it into the middle of the broom and have the pick-up brooms put it up into the escalator area.
I understand there's a cleanliness scorecard.
