A catchwater device is a large-scale man-made device for catching surface runoff from hills and the sky from precipitation by channeling it to reservoirs for commercial and domestic use later. Freshwater is a scarce natural resource due to pollution, droughts, and overpopulation. Catchwater is a sustainable mechanism to increase freshwater in areas facing droughts or polluted waterways.
