A floor for a water tank on a tank support tower is made of a dome of steel bar-reinforced concrete over a lower steel base in a central portion encircling a center access tower, the dome being surrounded by and continuous with an annular rim also of concrete reinforced with steel bars but over a circular steel beam at the base of the dome. Studs are welded from the concrete area into the steel base and the steel beam. The floor is built by first centering the steel base between a bottom section of the tank support tower placed there to start and the center access tower and then constructing the tank support tower by the slipform or by the jumpform method while raising the steel floor base, lifting the circular steel beam and placing it on top of the tank support tower, installing the lower portion or cone of the elevated water tank above the tank support tower, securing the steel base of the dome in place on the circular steel beam and, after positioning the steel reinforcing bars where the concrete is to be poured and welding the studs into the steel base and the steel beam, pouring and curing the concrete thereover. The floor is bounded on the outside by the cone or lower portion of the tank.
