The possibilities of using suitable plastic underdrain pipes as an alternative to the conventional metallic small diameter pipes are investigated. The lower material and fabrication cost and the light weight of the plastic are cited as reasons for choosing this type of underdrain pipe. Three different design underdrains were evaluated comparatively. Emphasis on the load carrying and the drainage capability of the materials is evaluated. Test results and discussion are given. The study concluded that the high-density polyethylene (HDPE) and the acrylonitrile-butadiene-styrene (ABS) samples performed well under all load tests. The drainage tests showed that the ABS samples performed better than the other plastic samples for the test conditions. The ABS and HDPE performed well under testing for load capability and drainage. Lastly, the ABS and the HDPE's resistance to corrosion was not affected by basic or acidic drainage water.
