Zusammenfassung:	Disclosed is a method for the construction of a prestressed concrete tank for the storage of liquids. The method includes erecting precast concrete panels on a foundation in a generally cylindrical shape while allowing an opening to allow the passage of people and equipment there through during the construction of the tank. Anchors are provided along both vertical edges of the opening. Strands are inserted into the anchors along both vertical edges of the opening and wire wrapped under tension over the outer surface of the inner tank wall. In one embodiment, a structural frame is secured within the opening and the strands are anchored to the vertical members of the structural frame. Once the opening in the tank wall is no longer needed, the opening is sealed with concrete panels. The sealed opening is then wire wrapped under tension using strands anchored to the anchors provided along both vertical edges of the opening.
