Constructing Drainage Swales

   One simple way to make water drain where you want it is to contour the ground into swales, or long depressions, that guide surface runoff . Water in swales moves naturally toward its intended destination, usually the street. A dry creek bed along the swale can make an attractive landscape feature.
   Keep in mind that swales work only after the soil is completely saturated.











Step by Step: Constructing A Drainage Swale

   1. Cut or grade a long V-shaped depression in the soil.
   2. Adjust the grade so there's at least a 1-foot drop for every 50-foot length of swale.
   3. Check with a line level if necessary.
