Sustainability of Underground Hydro-Technologies: From Ancient to Modern Times and toward the Future

An underground aqueduct is usually a canal built in the subsurface to transfer water from a starting point to a distant location. Systems of underground aqueducts have been applied by ancient civilizations to manage different aspects of water supply. This research reviews underground aqueducts from the prehistoric period to modern times to assess the potential of achieving sustainable development of water distribution in the sectors of agriculture and urban management, and provides valuable insights into various types of ancient underground systems and tunnels. The review illustrates how these old structures are a testament of ancient people’s ability to manage water resources using sustainable tools such as aqueducts, where the functionality works by using, besides gravity, only “natural” engineering tools like inverted siphons. The study sheds new light on human’s capability to collect and use water in the past. In addition, it critically analyzes numerous examples of ancient/historic/pre-industrial underground water supply systems that appear to have remained sustainable up until recent times. The sustainability of several underground structures is examined, correlated to their sound construction and regular maintenance. Moreover, several lessons can be learned from the analysis of ancient hydraulic works, particularly now, as many periodically hydrologic crises have occurred recently, overwhelmingly impacted by climate change and/or over-exploitation and degradation of available water resources

Ancient hydraulic systems for collection, transport and storage of water in karst settings of southern Italy.

The karst landscapes of southern Italy, even though showing lack or scarce presence of water at the surface, host a variety of ancient hydraulic works realized to collect and store water resources, at the advantage of the local settlements and for agricultural purposes. Ancient populations were forced to gain a deep knowledge of the territory in order to exploit the few available water resources, and developed at this aim several techniques, until reaching a high level of capability to collect, transport, and distribute water, even at long distances. Many areas in southern Italy still nowadays present hydraulic works of remarkable interest and historical values, which are briefly described in the present paper, together with other features used for water storage in karst

Collecting, transporting and storing water in karst settings of southern Italy: Some lessons learned from ancient hydraulic systems

The karst landscapes of southern Italy, even though they show a lack or scarce presence of water at the surface, host a variety of ancient hydraulic works realized to collect and store water resources, to the advantage of the local settlements and for agricultural purposes as well. Ancient populations were forced to gain a deep knowledge of the territory in order to exploit the few available water resources, and developed for this aim several techniques, reaching a high level of capability to collect, transport, and distribute water, even at long distances. Many areas in southern Italy still nowadays present hydraulic works of remarkable interest and historical value, which are briefly described in the present paper, together with other features used for water storage in karst. Studying these ancient works, and safeguarding them, should be a priority aimed at educating the young generations toward a sustainable use of the water resource. © IWA Publishing 2013
