A molded plastic leaching chamber, for dispersing or collecting liquids in soil, has a corrugated arch shape. The sidewall of the chamber is comprised of alternating slot-perforated peaks and valleys connected by slot- perforated deep webs. The unit surface length of perforated sidewall is greater than the unit length of chamber. A combination of interrelated dimensions and angles provide high leaching capacity, strength, and capability to nest for shipment. The sidewall is reinforced by vertically running ribs; the perforated web is reinforced by zig-zag struts. Ribs and struts are shaped and positioned to minimize blockage of the slot openings and injection molding.
