A STUDY ON THE BEHAVIOUR OF ALTERNATIVE DRAINAGE SYSTEMS IN LANDFILLS

Drainage and liquid collection systems are components of fundamental importance
in landfills and waste disposal areas. Sand, gravels and geosynthetics are materials commonly
used as filters and draining media in landfill drainage systems. However, the waste itself
contains elements that could be employed as drainage material. This paper presents an
investigation on the use of recycled rubble and tires (whole and shreds) as drainage materials of
domestic waste disposal areas in combination with geotextile filters. Two large experimental
cells and two metallic containers were employed in the research. The results showed the
potentials of the use of alternative drainage materials in combination with geotextile filters in
drainage systems of landfills.
