A weeping tile is a porous pipe used for underground drainage. The pipe is typically plastic with small slits cut lengthwise into it. It is buried and surrounded by aggregate larger than the slits. The aggregate rocks prevent excessive soil from falling through the slits into the weeping tile. With this arrangement, water in the surrounding soil above the weeping tile flows into the weeping tile. The weeping tile then drains into a storm sewer or a sump pump.
