Capillary permeation driven pottery pipe trench waste water treatment system

Abstract

A pottery trench system treats the down stream wastewater from a soil covered biological septic tank without power. The wastewater flows through porous pottery pipes buried underground surrounded with rock filter. U type polyolefin primary pipes buried under the pottery pipes prevent direct contamination of the underground water with the wastewater. Secondary porous pipes are buried under the polyolefin pipes with one end exposed to the air. Air is supplied from the pores of the porous pipes to the soil surrounding the trench. The system of this invention uses neither artificial chemicals nor powers. Maintenance cost is low. The system is constructed utilizing naturally occurring materials and plants. The effluent, water, exceeds the quality of needed for irrigation recycling or other effluent disposal methods.

What is claimed is  
     
         1 . An environmentally affirmative trench wastewater treatment system consists of pottery pipes, supplemented by secondary porous pipes, installed beneath the U type pipe surrounded with rock filters and one end open to the air, by supplying air to the soil and reserving overflow of the wastewater from the septic tank, rock filters, sands, U type plastic pipes, gauzes, and soil for effluents from a soil covered biological septic tank, the surface of which is covered with planted grasses and flowers of the area.
