Criss-cross the pie crust with licorice whips to represent the leachate collection pipes.

Laboratory testing of perforated leachate collection pipes.

Key words: leachate collection pipe, landfill, polymer pipe, trench, arching.

Laboratory investigation of the effect of coarse stone backfill on the performance of leachate collection pipe.

The design of a new laboratory facility for evaluating the structural response of small-diameter buried pipes (e.g., leachate collection pipes in landfills) is presented.

Key words: leachate collection pipes, HDPE pipes, leachate collection systems, landfill design.

The application of the new test cell is illustrated by using it to assess the response of a small-diameter landfill leachate collection pipe under two different backfill conditions.

Leachate Collection Pipe System - Perforated pipes, surrounded by a bed of gravel, transport collected leachate to specially designed low points called sumps.

Filter Geotextile - a geotextile fabric, similar in appearance to felt, may be located at the top of the leachate collection pipe system to provide separation of solid particles from liquid.

This paper reports the results obtained after 6 years operation of nine mesocosm experiments that simulate the 50 cm of the drainage layer closest to the leachate collection pipe in a landfill.

Outline: Work has been conducted to assess the impact of using large size gravel and large size perforations with plain HDPE leachate collection pipes to minimize biologically induced clogging.

Leachate collection layer - a layer of sand or gravel or a thick plastic mesh called a geonet collects leachate and allows it to drain by gravity to the leachate collection pipe system.
