Abstract
An assembly of hollow frustum-shaped bodies arranged and supported on a horizontal support structure is used to form a core structure for water retention cells. The assemblies are arranged in alternately inverted layers with the ends of the frustum-shaped bodies interconnected to form vertical support columns which are horizontally stabilized by horizontal support structure.
