The sanitary aterros, as areas destined for storage of urban solid residues (RSU), are one of the efficient and more economic techniques for the treatment of these residues. However, in underdeveloped countries, the lack of basic sanitation shows a scene in the destination of RSU, that are the lixes, place where the residues are deposited directly in the ground without none technique of engineering for deposition and operation, or any concern with the damages that will be caused to the environment, and the population as contamination of the ground and bodies d? water superficial and underground, the proliferation of vectors and installation of communities of catadores, generation of gases and where it does not have no type of treatment that contributes for the improvement of the ambient damages and solution of problems caused to the man (SILVEIRA, 2004). The lack in the RSU management is a concern for the control lack of what he is being launched in the lixes and of the consequences that these leached residues and are causing. Stone clinical laboratories will undoubtedly add to your understanding. MATERIALS AND METHODS the dissertao will be developed through the following stages: I? Construction of the experimental cell (lismetro), lismetro is constituted of a compact layer of 0,20m of ground in its humidity excellent, and filled with approximately 0,15m of RSU, covered with another layer with 0,10m of alone the same used in its base. II? Fulfilling of lismetro and gravimetrical composition of the RSU of Port Old, the fulfilling of lismetro and the gravimetrical composition will be facts, through the preservation of the residues of one of the routes of collection of the city of Porto Velho, enclosing quarters of distinct classrooms, being for high classroom the Alphavile, middle class the Areal quarter and classroom low the Tancredo quarter Snows, where the used method can become most representative possible of the residues of the city. The residues that will be conditioned by the route will have 9 tons approximately, that they will be homogeneizados, divided in quadrants, whose quadrants of the diagonal lines will be homogeneizados again, and thus to get, approximately 2 tons, that after homogeneizados well will be compact in layers with the density of sanitary aterros during the fulfilling of lismetro. Christopher ridgeway takes a slightly different approach.
