SCALL rainwater collection system

A rainwater collection and use system (SCALL) consists of a design that allows intercepting, collecting and storing rainwater. A technique for collecting this type of water, appropriate for small-scale agriculture, is to collect it from the roofs of houses, usually made of zinc, and farmers' warehouses, to convey it through gutters and plastic pipes to a storage tank. This system does not rule out the replicability of the technique on a large scale, depending on the precipitation in the area and the infrastructure of the catchment system. Current international experiences show that rainwater harvesting systems are a solution to the growing water scarcity in rural and urban areas, which is why their study is increasingly relevant worldwide.
