French Drain. A French drain is used to gather water. Categorized by the use of crushed gravel, French drains are placed in the places where water needs to be collected from, such as a swampy section of a yard or along the baseboard of a basement. In a yard, a French train can be created by digging a 6-inch-deep by 12-inch trench.
