PURPOSE: A prefabricated rainwater reservoir is provided to allow a worker to conveniently construct a reservoir by elastically controlling the expansion of the reservoir in construction, and to reduce the transportation time and transportation costs of a prefabricated block. CONSTITUTION: A prefabricated rainwater reservoir comprises assembly blocks(10,10'). The upper part and the lower part of an assembly block comprise a fixing groove(11) to insert a guide support bar(12). The guide support bar is fixed to a fixing wire(13) penetrating an assembly block. One side of the guide support bar is fixed to the fixing groove of the other side of the assembly block, and is inserted into each block assembled in the left and right direction.
