How to collect rainwater in ground catchments

Ground catchments are another way to collect rainwater. They work by capturing surface runoff from the rain (for example from a road) in a shallow area or basin. To make a ground catchment, dig a shallow depression in the ground and press down the earth or line it with clay, tile, concrete, or plastic sheeting. This reservoir can provide water for animals, for irrigation or for activities like bathing. If you want to use this water for drinking, it’s best to fence off the area to keep animals out, as they can contaminate the water. Tarmacked roads produce more run-off water than dirt roads but the water may contain harmful tar components for people and livestock and should therefore be used for irrigation only. 

The water collected from roofs or ground catchments can also be diverted into underground tanks. Storing water underground is a good way to keep water cool and covered. It may also be less costly than building or buying above ground tanks. Underground storage can be an affordable and practical solution for keeping a safe and steady supply of water.
