PURPOSE: A wall panel of a storage tank for water treatment is provided which has ensured durability against expansion and shrinkage due to a change in the temperature of water treated or the air by a seasonal change by forming an internal wall of the panel using stainless steel having good corrosion resistance, thereby increasing a life of the storage tank. CONSTITUTION: The wall panel(3) comprises: embossed reinforcement units(2) recurring in every direction on the wall panel(3); and a hemispherical expansion adjustment unit(1) provided between each of the reinforcement units(2), for absorbing shrinkage and expansion in a vertical direction.
