Abstract
The endplate of an arch shape cross section leaching chamber for dispersing liquid in soil has an inlet duct which enables the pipe delivering liquid to the chamber to be at higher elevation than the top of the chamber. Liquid flowing from the duct is guided downwardly by a channel and onto an integral baseplate extending into the chamber, to lessen any erosion of the soil within the open bottom of the chamber. Preferably, the endplate has double walls which, with sidewalls, form the channel. And, a slot opening near the bottom of the inner wall discharges the liquid into the chamber interior.
