Title:
LEACHING FIELD CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO1998053147
Kind Code:
A9
Abstract:
A leaching field constructed from a plurality of rectangularly shaped elongated geotextile covered in-drain core elements (16, 18, 20, 24, 26) provided alongside one another. The elements have equally spaced fold lines (16a, 16c, 16e, 16g) extending laterally across their adjacent semi-folded portions so that a stack of such elements in a flattened condition occupies a minimal space whereby these elements can be readily transported to the site. When expanded honeycomb configuration is achieved so that a self-supporting in-drain structure greatly facilitates construction of the leaching field without the need for templates and the like to support the structure during the filling of the voids between the adjacent in-drain elements themselves. If desired, expandable stakes may be used to support the in-drain assemblies in an optimum configuration.
