The Development Objective of the Vega Flood Prevention and Drainage Project of Argentina is to increase the resilience of the City of Buenos Aires to flooding, particularly in the Maldonado Vega and Cildáñez watersheds. It will aid in the betterment of the populations quality of life, a reduction in related economic losses, and the efficient delivery of essential services such as energy, transportation, health and education, among other benefits. In addition, the development of a large scale drainage infrastructure will strengthen the construction sector and create jobs. The major potential environmental adverse effects are associated with the construction of the tunnel and complementary works in the Vega basin, but are not considered irreversible. Key considerations associated with the physical location and characteristics of the project area include health and safety issues (for workers and the population), disruptions to a highly congested part of the city, and specific groundwater quality characteristics, as well as the management of excavation and the hauling of soil and waste generated during the construction of the drainage tunnel. There will be specific mitigation measures to ensure the proper management of waste materials from excavations, and identify and assess alternatives of potential disposal sites. The environmental adverse impacts of the construction stage are considered more important than those of the operational stage although they are reversible with the application of relatively routine and standard mitigation measures.
