Arrangement for collecting seepage water from depositories

摘要

To control the spread of water from a waste depository body, a drainage layer and a sealing body are provided below the depository body. A control room underlies a major portion of the depository body and a major portion of the sealing body for facilitating visual inspection and repair of the sealing body and the drainage layer. The sealing body includes one or more plastic sheets inclined at an angle with respect to the horizontal to define water collection fields or areas. The sealing body may comprise a platform forming the ceiling of the control room, the ceiling platform being provided with pipelines for drawing off depository gases and with passages or openings for draining off seepage water.
