A leaching chamber for burial in the ground includes non-symmetrical corrugations extending laterally across the leaching chamber. Each corrugation has a ridge and a shoulder with the ridge being higher than the shoulder and sloping down from the ridge to the shoulder. Additionally, the ridge of each corrugation is also wider than the shoulder. The corrugations are oriented relative to each other such that the ridge of each corrugation is adjacent to the shoulder of an adjoining corrugation.
