Abstract: Snow removal equipment includes a snowblower on a truck delivering snow into the top of a snow reduction chamber on the back of the truck. The snow falls on several spaced apart, horizontal layers of hot, mutually parallel closely spaced tubes. The snow melts when it hits the tubes and the resulting liquid water is stored in the chamber until it is discharged from the chamber into a storm sewer.
