The present invention relates to a mobile pumping station (10) comprising a mobile base frame (12), a primary feed hopper (14), a primary conveyor system (16), and a slurry vessel (18). The primary feed hopper (14), primary conveyor system (16), and slurry vessel (18) are all mounted to a support structure (20). The support structure (20) is fixedly connected to a turntable (22) which is rotatably mounted to the mobile base frame (12). The slurry vessel (18) has connected to it a liquid supply via a pipeline. A water supply pump is provided on land for pumping water to the slurry vessel (18). The mobile pumping station (10) further comprises a relatively large slurry pump (50) used to pump slurry from the base of the slurry vessel (18). The mobile pumping station (10) can be used to move predominantly sand from a beach area that is being excavated. An excavator or wheel loader is used to dig sand from the beach and load sand into the feed hopper (14). The primary conveyor system (16) carries the sand to the slurry vessel (18). A predetermined flow of water is pumped into the slurry vessel (18). The quantity of water pumped to the slurry vessel (18) is controlled so that the resulting slurry can be pumped from the slurry vessel (18) via the slurry pump (50). As the beach portion adjacent the feed hopper (14) is excavated the support structure (20) can be pivoted relative to the mobile base frame (12) so as to conveniently locate the feed hopper adjacent the next section of beach to be excavated. The mobile pumping station (10) can then move via the track mounted base frame (12) to another location on the beach.
