Underground water storage and reuse of water in battling drought
With its extremely elongated shape, 4,000 kilometres from north to south, and geographic diversity, Chile has a multitude of water issues. The availability of water is one of the most urgent issues. The north of Chile in particular is extremely dry. In 2019, the Netherlands and Chile started the GIRAgua recharge pilot project aimed at water retention and underground storage in the Coquimbo region.
The GIRAgua recharge pilot project is looking at the catchment area of the Elqui River which flows from the Andes to the Pacific Ocean. This catchment has hardly any water in the dry season, but does have water in the rainy season which then disappears straight into the sea. The project consists of aquifer recharge and underground storage practices to contribute to integrated water management of the Coquimbo region. The project is an initiative of a Dutch consortium led by Deltares and co-implemented with Chilean partners. Financially, GirAgua is supported by the subsidy scheme of Dutch Partners for Water programme and the Government of the Coquimbo region.
