For the public area of the city this collection includes the sidewalks, parks, fountains and streets. City workers routinely collect trash throughout the day. In fact, they collect litter off the sidewalks and from the grass in the parks so frequently that it is rare to spot trash lying out in the open in these spaces! When it comes to collecting trash from the private sector of the city, which includes people's homes and businesses, there is a carefully planned system in place.
