An ordinary perforated drainpipe is often clogged with fines due to soil erosion or breakage of rock mass. Three different types of fiber drainpipes were proposed and tested for drainage capacity using laboratory soil box. A perforated drainpipe with inner fiber layer showed a good performance of drainage and selected for field testing. From the field testing, a perforated drainpipe with inner fiber layer drained well compared to an ordinary perforated drainpipe.
