Abstract: The temporary storm water storage system comprises a storage tank, an inlet pump, an outlet pump, a graded top drain, a plurality of sensors, a timer, a first valve, a second valve, and a plurality of interconnecting pipes. The temporary storm water storage system may pump flood water from a street into the storage tank when flooding is detected by the plurality of sensors. The temporary storm water storage system may pump the flood water from the storage tank into the street after a predetermined time interval once the flooding has subsided. The flood water pumped from the storage tank to the street may be drained from the street via one or more catch basins into a storm drain.
