Abstract
Barriers are placed over openings in the opposing sidewalls of leaching chambers used for receiving and dispersing water within soils. The barriers enable outward flow of water and hinder inward movement of soil. Exemplary barriers such as geotextile may be attached directly to the sidewall of the chamber. In another approach, panels comprised of barrier material contained with a frame, and the panels are placed on the chamber sidewall at the location of the openings.
