Abstract
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.
