City of Casper Offices Open Tuesday; Garbage Collection Resumes All city services will resume operation as they can, including garbage collection. Ccollection crews will work Tuesday through Saturday, and routes will be one day off their normal collection day, solid Waste Manager Cindie Langston said. For example, the Monday route will be collected on Tuesday. “We expect garbage collection will be running slow, as our trucks try to navigate the deep snow on residential streets and alleys,” Langston said. "Though we may not be able to reach all dumpsters, we will develop a plan to collect those we cannot reach."
