Environment: All-women research team designs first anti-flooding roundabout


ROTH₂O  is the first roundabout improving urban traffic by avoiding sudden flooding from extreme weather events, thanks to an underground reservoir holding up to 70 cubic meters of water[1].  Designed by an all-female team, ROTH₂O  won the 1st edition of Climathon-Rome, the marathon of ideas against climate change organized by ENEA and Roma Capitale. "We are closely following the work of these young researchers, supporting them in the design of each single part of the roundabout with a detailed analysis of the implementation costs. The objective  is submitting the project to companies as soon as possible, and some companies  in the building sector have already shown some interest",  Gabriele Zanini, Head of the ENEA Division" Models and Technologies for the Reduction of Anthropic Impacts and Natural Hazards ", explained.

"We have calculated a 10% cost increase for the installation of ROTH₂O as compared with a standard roundabout of the same size. As for size, the cost effectiveness of the investment is guaranteed starting from roundabouts with a 13 meter diameter  and a 7 meter reservoir, but the project is easily replicable on larger portions of urban land and of a different shape", Zanini said.

City streets flooding are sudden and dangerous events increasingly common, as a result of soil sealing and heavy rainfall caused by climate change. "ROTH₂O, in addition to reducing electricity consumption thanks to the absence of traffic lights, is a mitigation tool of urban flooding, minimising diversions and delays caused by traffic in the days of heavy rainfall. Its underground basin - a modern reinterpretation of the Roman impluvium- is both a drainage tool and a water reservoir, which can also meet specific needs of neighborhoods, starting from the reduction of the overload of sewage networks. Depending on the needs, the water can be used to irrigate green areas, clean roads, supply firefighting networks and, where possible, contribute to groundwater recharge, " Agnese Metitieri of the ROTH₂O team, explained.
