necessary. Their job is also closely connected with the maintenance crew.
The maintenance crew is led by the senior support officer who oversees the whole process and makes sure that every container is in prime condition. You might not realize, but every dumpster contains several smaller components that will wear out over the time. Maintenance crew checks those components and replaces them before they wear out completely and cause injuries to people. This team also works on repairs of commercial dumpsters as they are more complicated than regular containers and thus they may even go to a location of the dumpster to repair it.
