Abstract

See full text

The installation of prefabricated drains in a horizontal, generally co-planar pattern below the surface of the CCR with suction or a vacuum to withdraw water from the CCR material to lower the water level down to the level of the prefabricated drains below the CCR surface. Dewatering may be coupled with imparting vibrations to the material to further promote both additional dewatering and compaction of the CCR material in the pond. A suitably graded bottom ash, fly ash, sand or large-diameter-solid particle layer may be added on top of the horizontal drains to enhance dewatering of finer CCR material.
