Abstract
A leaching chamber for burial in the ground includes biased ends which permit a series of chambers to arch clockwise or counterclockwise or to continue straight to form a leaching field. Each chamber is identical to every other chamber and includes identical mating flanges. For tighter arches, short adaptors can be used which have ends identical to the chambers.
