A drain field and a drain field assembly for use with a sewage disposal system are provided that do not require the use of aggregate in the form of rock, gravel, shale, or the like. The assembly contains a distribution pipe having a plurality of holes disposed along its bottom half for receiving liquid effluent. Alongside and beneath the distribution pipe are positioned a plurality of void pipes that serve to retain and distribute the effluent received from the distribution pipe. Draped over the top and along the sides of the assembly is a protective sheeting that is impervious to soil and liquid permeable that serves to keep soil from entering the pipes and also to aid in evapotranspiration. The drain field of the present invention contains the assembly positioned within a trench and covered in backfill material.
