<p>The water tank comprises a number of peripherally disposed modular wall components, each modular wall component defining a radially inner exposed surface, for direct engagement with the water inside the water tank, and a radially outer formwork area, for receiving liquid concrete to be cured. An integral hinge edgewisely interlocks each pair of successive modular wall components. An expansible joint is mounted into each hinge, wherein the expansible joint cooperates with the hinge so as to releasably interlock the modular wall components in their peripherally disposed fashion. The expansible joint provides a water tight seal at the hinge when soaked in water for a sufficient period of time. A second bevelled seal joint is further mounted against the hinge adjacent each wall component inner exposed surface spacedly from and radially inwardly from the expansible joint. Both first and second seal joints are for direct liquid engagement with the water tank water. A biocide agent is integrated within the radially outward second seal joint, wherein bacterial/fungus contamination of the water tank water is mitigated.</p> |
