The aqueducts of the roman empire are marvels of engineering and soaringly elegant design .
罗马帝国的导水管是工程奇迹，设计优雅高贵。
A great deal of water is often lost in association with irrigation through evaporation from open storage areas ( e.g. reservoirs ) and open transport canals and aqueducts .
灌溉中有大量的水，往往是在露天储存区（如水库）及开放交通的运河和沟渠中通过蒸发流失的。
Those " trillions of dollars " are represented by the dams , canals , aqueducts , and pipelines that have been used throughout the developed world to safeguard drinking water supplies .
代表那“数万亿美元”的是发达国家在保卫饮用水供应过程中使用的水坝、运河、沟渠和管道。
Today , water has drifted so far from civic celebration that many people visit the roman aqueducts without any sense at all that they moved water , or how .
