Abstract
An aggregate chamber for leaching effluent comprises a chamber cavity, at least one panel positioned along a periphery of the chamber cavity, and aggregate for filtering effluent. The chamber unit may include a plurality of foldingly connected panels, and at least one conduit for delivering effluent. A leach line comprises a trench excavated in a leach field, and a plurality of chamber units having a cavity, at least one panel, and aggregate for filtering effluent. A leach field comprises a source of effluent, a plurality of trenches excavated in the soil adjacent the source of effluent, and a plurality of leach lines positioned in the plurality of trenches in fluid connection with the source of effluent, each leach line having at least one chamber unit comprising a cavity, at least one panel, and an aggregate for filtering effluent. A method aspect of the invention includes leaching effluent by conducting effluent from a source to a chamber, filtering the effluent through an aggregate, and leaching the effluent into the leach field. A method of constructing a leach field comprises excavating a plurality of trenches, positioning a plurality of panels in the trenches to define a plu…
