ABSTRACT:
There is disclosed a method and apparatus for disposal of snow in urban areas. Snow is disposed of using existing manhole or other connections to sewer systems with a portable or mobile disposal unit formed of a snow receiving bin, a grinding device, apparatus for projecting the ground snow in a controlled and linear confined manner and into a trajectory downwardly into the sewer and preferably with sensing apparatus to sense whether there is a blocked sewer conduit as well as to determine the load carrying capacity of the sewer liquid. In this way, the grinding device may be driven by variable speed motors. The system and method permit the use of already existing sewer systems, and is more economical than trucking snow to disposal sites. The system and method also permit the ready disposal of snow in areas where there are no disposal sites or where disposal sites are not allowed.
