A tank of generally oval configuration created by the use of a plurality of curved, precast concrete panels of uniform size and rectangular configuration. Each panel is constructed utilizing a diaphragm liner either made of corrugated structural material or else of rubber-like material. The diaphragm liner of corrugated structural material possesses a degree of arcuate curvature, so as to be concave on one side and convex on the other. Both types of liners are intended to receive concrete poured to a desired depth on the convex surface of the liner, with the outer surface of the concrete then contoured to a finished condition to form the exterior surface of the tank made from the panels. One or more horizontally disposed ducts are installed in the concrete prior to hardening, placed in accordance with a consistent pattern. As a result, when a suitable number of precast panels are installed on a floor surface to form a generally oval configuration, it can be expected that each set of horizontally disposed ducts will reside in substantial alignment, and thus be in a position to receive an elongate tensioning member. After the precast panels have been drawn together, a suitable fastening arrangement is utilized to hold the precast concrete panels together to form a tank usable for a variety of purposes. This invention comprehends the novel method of making a tank as well as the construction of tanks of circular, elongate or elliptical configuration.
