V.E.R.A. project

Save every year at least 25% of the potable water consumption, combining ancient technology and processing power of GIS. Water saving is met by gathering, for all the non potable use, rain water fallen on the roof of the building and storing it in special tanks. The engineering design is wide range and smart: it creates a demand-harvesting capacity map that combines Comunity’s requirements, citizen water demand, rainwater harvesting capacity and hydraulic security.
Technology validated in lab.
Basic technological components are integrated to establish that they will work together. This is relatively “low fidelity” compared with the eventual system. Examples include integration of “ad hoc” hardware in the laboratory.
Most of the components (collection of information, rainfall simulation, engineering tank design and sizing, upscaling of water saving potential) have been formulated and integrated into an unique toolbox. Computer-based simulation tests have been performed in the Venice districts (25 municipalities), and the modeling strategy validated. The innovation need further development to test the technical combination of ancient and GIS-spatial analysis technologies. Computer simulations need to be validated against on-site experimental tests.

How does it work?

V.E.R.A aims to reduce the negative effects of future scenarios of water scarcity by reducing the domestic water consumption by 25% yearly. This is reached combining the old technology of the ancient Repubblica Serenissima di Venezia with spatial analysis and GIS technologies. Saving is obtained gathering rainwaters fallen on the roof of the buildings, and storing it in reservoirs. Each system is designed and sized according a demand-harvesting capacity map which takes the water demand of each building type and its location. V.E.R.A. combines comunity’s and citizen water requirements, neighborhood’s rainwater harvesting capacities and the district’s hydraulic security.
