Swales - harvesting rainwater to rep
Rain water harvesting into the ground/ contour ridges/ swales
The ‘S’ Principles: Looking at the rain as the main source of water, we need to harvest it at the source by slowing it down and stopping it from flowing using swales and mulch or ground cover. Swales are ditches on the ground that are dug truly on contour. Swales cause flowing water to spread slowly and thus more of it will get a chance to sink into the ground thereby recharging the ground water store. Over time the springs that may have disappeared in the past will spring back to life. The contours along which we dig the swales are determined using a simple instrument called an ‘A’ frame.
