Abstract

Home sewerage treatment system by surface discharge is a second rate treatment where sewerage application occurs on the upper part of the ground at a determined slope so that it slides down into a canal or receiving body. Application occurred intermittently and the system under analysis within the CODAY treatment station; the soil was clayey and characterized by low permeability. Mean ground slope was approximately 10% and Tifton grass (Cynodon dactylon) was placed at the effluent to guarantee an increase of absorption rate of the nutrients in the soil and loss of water by evaporation-transpiration. Vegetation increased residence time of the effluent in the soil and worked as a barrier against free discharge, avoiding erosion and retaining suspended solids. Current analysis deals with the contribution of the effluent in ETE CAPIM to increase the pollution load of the Córrego das Toldas, the receiving body, or rather, to verify whether the method is really efficient for the situation in the municipality of Uberaba MG Brazil.
