|WATER CATCHMENT FROM COVERING
Definition characters description and diffusion
Terrace habitation is the most apt method for the collection of rainwater. The practice was diffused in the Byzantine world and in an Islamic environment.
General characters description and diffusion
In Yemen, even houses built with raw earth allow the collection of water thanks to the impermeability of the lime. Every mosque works as a collector and water captured on the terrace is channeled into the courtyards. In the Sassi di Matera, the roofs of houses do not come out of the walls, but the rest on the inside of the terrace so as to permit the channeling of rainwater using the vertical ducts of the cistern dug in the courtyard. The practice is associated with the creation of suspended or hanging gardens on the terraces that contribute to the maintenance of optimal technical conditions in the houses.
Advantages and sustainability
Roofs or covers are used to aid in water catchment methods. Since these roofs serve a dual purpose they contribute to the sustainability of the technique.
