ABSTRACT:
A leaching system (10) includes arched leaching chamber sections (12) and an angled adapter (18) connected adjacent chamber sections at a 22.5.degree. angle. The adapter includes a first portion (122) having sidewalls (140, 142) spanned by a vaulted portion (144) and a female end collar (126). A second end portion (124) has sidewalls (140, 142) spanned by a vaulted portion (144) and a male end collar (130). The first and second end portions are connected at an arched, vertical ridge (136). The adapter connects the leaching chamber sections in a nonlinear configuration to curve the leaching system to follow contours and avoid obstacles.
