Day Tanks were originally specified as an above ground, local, source of fuel for emergency and stand-by generator sets. These tanks were sized to automatically maintain 24 hours of fuel next to the generator set. As the industry grew, however, the term "day tank" became synonymous with any above ground tank that has a pump, motor and control circuitry mounted on top.
