Abstract
A leaching chamber for gathering and dispersing liquids in soil has an end with an angled terminus, so that chambers may be connected as a string in a rough curve. An angled chamber end is severable from the chamber at an indicant, to convert the chamber to one having a different angled end, e.g., a square end. Intentional looseness of fit at the joint enables further angular adjustment. Thus, a combination of chambers with original and severed ends, having a basic 6 degree end angle and 3 degree of looseness, can form a chamber string where the alignment angles between adjacent chamber axes range from minus 3 to plus 9 degrees. Such leaching chamber strings may be installed in practically level trenches which follow the contour of a hillside.
