Solid waste, fecal sewer or used water cause pollution if they will not be managed rightly or infiltrated in the soil. This management sometimes is not technically and economically possible. To resolve this problem, one experience to treat used waters, fecal sewers and biodegradeable solid wastes of a house was developed. This treatment unit is composed basically by aerated filter and biodigester with accessories to nutrition and cleaning. The final products are filtrated and aerated water, combustible gas and fertilizer.
