Abstract
A plastic leaching chamber having an arch shape cross section and corrugations running transverse to the chamber length has peak corrugations which are substantially wider than the intervening valley corrugations. One or more hollow pillars extend downwardly within the interior of some chamber embodiments, to support the load applied to the chamber. Chambers nest together to form a stack of chambers for transport or storage. Chambers having different widths and vertical profiles have common size connectors for interconnecting as chamber strings.
