The water from the wastes (W) consists approximately 25% of thetotal wastes volume. The retention capacity (∆R) was determined at the level of 50% of the watercontent of wastes (from tests on the Lubna and Radiowo landfills).It was assumed that the landfill surface obtained 21.64 ha, while the surface of open waterreservoirs was 0.28 ha. The components of the average annual water balance for the Lubnawaste body are presented in Table 3.11
