1. A compost leachate distribution device comprising a composting chamber for receiving material to be composted, a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber and a leachate mixing arrangement comprising a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads for mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement comprises a dosing arrangement for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber, wherein the leachate mixing arrangement comprises a venturi mixing tube provided between the first inlet and the outlet of the mixing chamber and a dip tube providing a fluid path from the leachate collection chamber to the venturi mixing tube, wherein the venturi mixing tube and the dip tube act as said dosing arrangement.
