Argentina advances water infrastructure upgrades in Buenos Aires, Tucumán and Chaco

The Buenos Aires provincial government awarded the renewal of the French–Carlos Casares aqueduct to Oreste Durante S.A., allocating more than AR$19.7 billion for a new parallel conduit that will replace a strategic segment and serve the towns of Carlos Casares, French and part of Pehuajó over a 720‑day period.

In the same province, the Tramo V of the Salado River basin master plan progressed, covering 59 municipalities and benefiting over 1.5 million people. The project, financed partly by a US$110 million loan from the European Investment Bank and provincial funds, includes 95 km of river work, bridge reconstruction and flood‑mitigation measures, with a total estimated cost of US$138 million.

In Tucumán, the Villa Muñecas water‑treatment plant received an AR$800 million valve‑replacement upgrade, a 60‑day intervention that will improve service for roughly 800 000 residents and form part of a broader modernization program.

The Chaco water utility SAMEEP installed a new pumping system on the First Interior Aqueduct, restoring and enhancing service for six towns in the province’s southwest and preparing for future linkage of a second aqueduct.

The Buenos Aires government also presented a US$270 million sanitation plan for the Río de la Plata basin, featuring an advanced primary treatment plant in Berisso, an underground conduit and a sub‑river discharge system, seeking World Bank financing and additional provincial investment.
