A STUDY ON THE BEHAVIOUR OF ALTERNATIVE DRAINAGE SYSTEMS IN

SUMMARY: 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. 1
