SCALL rainwater harvesting system

Rainwater harvesting and use systems (SCALL) intercept, collect and store rainwater, and can be used in small-scale agriculture on the roofs of houses and wineries.

A rainwater harvesting and use system (RACS) consists of a design that allows for the interception, collection and storage of rainwater. One technique for collecting this type of water, appropriate for small-scale agriculture, is to do so from the roofs of houses, usually made of zinc and farmers' cellars, to conduct 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 rainfall in the area and the infrastructure of the collection system. Current international experiences show that rainwater harvesting systems are a solution to the growing scarcity of water in rural and urban areas, which is why their study is increasingly relevant worldwide.
