Cochran said. "If I swept through their subdivision and then dumped this truck, they'd think 'My God, this is coming off my street?'"The sheer weight of the trash and gravel can be considerable. Public Works Director Jim Karch said Public Works employees can recover as much as 25 to 30 tons of material per day during some spring months, or in the fall when leaves cover the streets.Cochran said that might mean he can't get down one block of a side street without having to turn the brushes off and head back to the city's transfer station on West Oakland to dump his cargo.

After sweepers have been over the streets repeatedly, they may pick up just two to four tons in a day, Karch said.Bloomington doesn't track how much debris its sweepers collect. Robin Weaver, public works director for the town of Normal, said a year of sweeping removes an estimated 4,600 tons of dirt and debris from Normal's 430 lane miles of streets. Normal has fewer sweepers, and a little more than half of Bloomington's total area to cover.Bloomington's sweepers operate day and night, five days a week, as weather permits, Karch said. Cochran said the sweepers hit the downtown Bloomington area during the night twice a week every week. The late shifts ensure there's less traffic and fewer cars to get in the way.Karch said Clean Water Act regulations require cities to take care of their streets, and impose hefty fines if they don't.
