Apparatus and a method for constructing a sewage drain field without a rock media. The drain field includes a plurality of lengthwise connected drain pipes suspended above the trench bottom within a channel formed by a plurality of elongated mesh-like channel forming members and in overlying relation to which assembly a porous, conforming length of sheet goods is mounted. As necessary, mesh-like end caps seal the ends of the channel forming members. Independently mounted filter elements may be used to filter the grey water and/or channel the grey water in lieu of the conduit.

In a sewage disposal system apparatus for distributing effluent over the trenched surface of an effluent absorption bed and wherein no filler gravel is required comprising: (a) a lightweight soil supporting framework including a plurality of rib members coupled to one another to subtend an elongated hollow chamber having an open bottom and ends and mountable in a prepared trench; (b) a rot resistant, soil supporting first meshwork mounted over said assembled framework, the porosity of said meshwork being dense enough to prevent the infiltration of dirt and rock into the chamber, yet permit evaporation and the permeation of liquid therethrough; and (c) means suspended within said hollow chamber for receiving and distributing effluent over the surface of the absorption bed; (d) the effluent thereby being absorbed by the underlying soil and evaporating through the air and liquid permeable walls of said apparatus.
