In order to determine the feasibility of using water treatment plant sludge as a construction material, sludge samples were collected from two water treatment plants and tested. Both chemical and physical characteristics were determined. Water content, specific gravity, grain size, and pH values of the dewatered sludge were determined. It was noted that the permeability characteristics of the sludge samples were not altered by soaking in a landfill leachate. Other tests included compaction test, consolidation test, and pinhole dispersion test. The experimental results indicate that the water treatment plant sludge is impervious and nondispersive. It was noted from these tests that one of the water treatment plant sludges investigated has the potential to be used as a liner for sanitary landfills and the other to be used as a fill to support light loads.
