Abstract: A wheeled trailer main frame is provided including an upwardly opening tank supported therefrom for receiving a quantity of water therein from a below frost line pressurized supply of water. Motor driven agitator structure is disposed in the tank for mechanically agitating and rendering turbulent the water therein to thereby effect some heating of the water as a result of the turbulence thereof. Water is continuously admitted into the tank from the below frost line supply thereof and bulk quantities of snow intermittently may be dumped into the tank for melting therein as a result of the heat of the water supplied to the tank from the below frost line supply. An upper weir-type water outlet is provided and is operative to discharge water from the tank at a rate substantially equal to the rate of water supplied to the tank, plus the water volume added to the tank as represented by the intermittent dumping of bulk snow therein.
