A main problem refers to the sanitary discharges generated in rural communities, since they cause health and safety problems due to the lack of adequate drainage and a suitable treating system. Resulting from the need of sanitary discharges to be treated, an anaerobic system has been created; this includes an integral handling of excreta which is environmentally efficient, since it may reduce the pollutants from the phreatic surface such as rivers and underground aquifers, also reducing the emission of atmospheric gases of green house effect. On the other hand, the invention is technologically viable and cost affordable due to the use of the generated methane gas. In addition, the invention offers a sustainable handling of the residues with biogas production (methane gas) and a substrate as a soil enhancer. The present Project complies with the current standards of: NOM-003-SEMARNAT-1997 and NOM-004-SEMARNAT-2002. The sanitary discharge resulting from a toilet is led to a sanitary man hole which is also fed from the sanitary discharges of animal excreta, the discharge being subsequently led to a biodigestor, which, by means of an anaerobic digestion, performs the degradation of the organic matter in about 50% and 60%, odour reduction in about 80%, the anaerobic degradation generating methane gas, which may be used in a burner that is supplied by biogas through a piping system. The invention may also have a dredging system for sludge, which must be removed and used as soil enhancers (bio-fertilizers). The biodigestor effluent is now the influent of a wetland where the final treatment is performed, the inner portion of the wetland including gravel for supporting plants intended to depurate wastewaters and absorb heavy metals. The wetland effluent may be useful for the agricultural irrigation of plants of long stems and ornate plants.
