Well system inspect as consequence agricultural emergency in Chile
January 29, 2013, Chile.
The 23 wells built by the Department of Hydraulic Works MOP of Chile, are part of the Integral project of Water Infrastructure for Aconcagua, which generate a large supply of water deficit areas. An estimated that extracted flow is 3.5 m3 / s. Another innovative initiatives to increase water availability is the infiltration or aquifer recharge. Therefore, the Ministry of Agriculture, through the CNR is developing recharge studies in rivers Copiapó, Marchigue, Ligua and Petorca. It works to reverse fifty years of delay in the development of irrigation works and mitigating the effects of climate change.
In the Region of Valparaíso, were inspected the operation of wells Curimón sector, in the Aconcagua Valley, those with new technology for better performance and greater extraction of water for the irrigation season. The 23 wells built by the Department of Hydraulic Works MOP are part of the Water Infrastructure Integral Project for Aconcagua, which will create a great contribution to deficit areas, especially those located downstream. Extract an estimated flow 3.5 m3 / s, of which 1 m3 / s will benefit the lower part of the first section of the river Aconcagua, distribution is done through Curimón channel and 2.5 m3 / s remaining be conduced directly to the benefit of the irrigation areas of the third section.
Another innovative initiatives promoted by the Government to increase water availability is the infiltration or groundwater recharge. Therefore, the Ministry of Agriculture, through the CNR is developing recharge studies in rivers Copiapó, Marchigue, Ligua and Petorca, in order to analyze and develop alternatives to pre-feasibility level, as regulation works groundwater for use in irrigation, proposing infrastructure for optimum utilization of surface and groundwater resources.
The Government of President Piñera is committed to finding new alternatives for water accumulation. It is working tirelessly to reverse fifty years of delay in the development of irrigation works and mitigating the effects of climate change, it is here to stay, said Agriculture Minister Luis Mayol. The ministerial authority stressed that these true underground reservoirs present a great economic advantage, since the cost per cubic meter is between thirty and fifty pesos, which do not compare to the nearly one thousand that cost, on average, large surface reservoirs . These projects will complement the existing surface infrastructure and the National Plan of Reservoirs.
Meanwhile, the MOP is promoting a pilot groundwater recharge in the Aconcagua basin, through the construction of two pools that will form the basis for testing the performance of the system. In this regard the Minister of Public Works Loreto Silva said that from March we will work on a pilot project to create true infiltration groundwater to improve the quality of the groundwater in this area. In addition, the authority said that the MOP is working facing drought, but also with a long term perspective to ensure the resource for all individuals and for irrigation. We can safely say that this year the water for people is assured and that the condition of irrigation is much better, although we are experiencing drought for the third year running.
For other part, the executive secretary of the CNR, explained that the project of artificial recharge of aquifers has a great socio-economic value, since Chile has a structural water deficit. We loss about 175 billion cubic meters annually discharge at sea, through the main basins of the country. This reality requires us to move quickly in water infrastructure, and we hope to start the infiltration in Ligua and Petorca area this winter so to store the water that today draining into the sea without being utilized.
