The potentiality of water treatment sludge as the alternative liner and cover materials in landfills is investigated. A series of tests were performed on sludge admixtures to examine their compaction, compressive strength, leaching, hydraulic conductivity characterisit its and the compatibility with representative leachate within landfills. Results from the tests show that low hydraulic conductivity can berachieved with sufficient stabilizer contents and curing. It is recognized that the hydrauac conductivity decreases with increasing bentonite content and the percentage of bentonite needed to make the hydrauic conductivity below 1$ imes$10-7cm/ sec was 40% for water treatment sludge. It was found that the effect of the municipal waste leachate on the hydraulic conductivity of the admixtures is negligible.
