The water balance is an important aspect on development of a landfill project, and the choice of material for the cover layer will influence the generation of percolated liquids. Considering the composition and characteristics of cover layers, it becomes necessary the conventional material substitution. Therefore, this study compared the construction civil waste (CCW) to the soil from the university campus - UEFS in Feira de Santana/BA as used in evapotranspiration cover layer for landfill, using the water balance models Fenn et al. (1975) and São Mateus et al. (2012). The results showed that both materials have the same behavior for the Fenn et al. (1975) method, where the CCW generates less liquid than MSW to the ground. By the method of São Mateus et al. (2012), the CCW and the soil allow the passage of water to the MSW in different behaviors, and the soil promoted greater liquid infiltration, about 95.5% higher than the CCW. When the methods were compared, São Mateus et al. (2012) presented higher water infiltration to the MSW in the simulation with the soil, in relation to the method of Fenn et al. (1975), and smaller with the CCW, this occurs due to the distinction of the input parameters for the materials, highlighting the influence of the permeability coefficient in the water balance.
