Abstract

A leaching field module (10) including a plurality of arrayed pockets (12). Preferably the pockets are arrayed edge to edge and in generally parallel rows. The pocket edges may be connected to form sleeves. At least some of the pockets have a stiffener (32) disposed therein so that the pocket and stiffener combination may define an internal void area. The pockets and stiffeners are connected to provide the leaching field module. In some embodiments, the module advantageously has void areas between connected pockets. In some embodiments the stiffeners and pockets can be deformed to expand the module.
