A transportable system for receiving, storing, and distributing granular material includes a surge bin with two storage compartments. A distribution conveyor assembly is movably mounted to the surge bin, has two conveyors, and can be manipulated to discharge into selected adjacent bins. An elevating conveyor assembly has two conveyors and each can discharge into either compartment of distribution conveyor and into either of the distribution conveyors. A receiving conveyor assembly has first and second receiving conveyors configured to receive granular material from side by side transport vehicles at the same time and deliver same to the input of either elevating conveyor. A surge bin output diverter assembly can receive granular material from either one of the storage compartments and direct same into either one of the first and second elevating conveyors for elevating to either one of the distribution conveyors.
