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.

Angled adapter for a leaching chamber system

A leaching chamber (10) includes first and second side walls (46) which have louver sections. The side walls are connected by vaulted portion (48) to define a chamber potion (12) terminating at a first end (16) and a second end (18). Male and female coupling collars (20, 30) are integrally connected with corrugation peaks at the first and second ends. An intermediate peak or structure (70) has a first portion (72) with a profile of the male coupling collar and a second portion (74) with a profile of the female coupling collar upon cutting between the two portions, two subchambers (12', 12') are formed each having a female coupling collar at one end and a male coupling collar at the other. An inlet end cap (14) is telescopically connected to the female coupling collar (30). The inlet end cap (14) has a sleeve (102) to receive a conduit carrying effluent and a diffuser (104) to diffuse the received effluent. The diffuser includes a sloping surface with diverging ribs (106). A sloping surface (108) extends along a bottom edge of the end cap aligned with the diffuser to absorb the erosion inducing force of fluid falling from the diffuser.
