FIELD: methods of sewage gas gathering and withdrawal; applicable in neutralization of solid household and industrial wastes by burial them at wastes grounds. SUBSTANCE: method includes preparation of ground base; mounting of system of vertical gas drainage from holes-tubes with perforated walls, laying of wastes by layers, mounting of system of horizontal gas drainage on surface of each completed layer of wastes in the form of drains, isolating coating of surface of formed ground, withdrawal of sewage gas from holes. Holes-tubes of vertical gas drainage of definite height are installed on foundations distributed over ground surface. Then internal space and outer surface of each hole is filled. After laying of the first layer of wastes, formed on its surface are horizontal drains adjacent outer filling of holes. Perforated holes are added to definite height. Outer surface of holes is filled with draining material for height of next layer of wastes. In last cycle of hole adding, holes are provided with walls without perforation and height rising above surface of formed waste ground and without filling of their surface with draining material. EFFECT: higher efficiency. 3 cl, 4 dwg
