IDE builds Aconcagua desalination EPC

Published May 27, 2026 by The Daily Scout

- IDE Technologies said on May 27 it is building the Aconcagua desalination plant in Chile under a full EPC contract for Aguas Pacífico SpA. - The project’s key figure is 86,400 cubic meters a day, or 1,000 liters per second, from a seawater reverse-osmosis plant in Quintero Bay. - IDE’s project page and company materials identify Quintero, Valparaíso Region, and Aguas Pacífico as the next-step reference points.

Why it matters

IDE Technologies’ latest push on the Aconcagua desalination plant puts a long-running Chile water project back into view through an EPC lens. The company’s project materials describe Aconcagua as a full engineering, procurement and construction job for a seawater reverse-osmosis plant with nominal capacity of 86,400 cubic meters a day in Quintero Bay, in Chile’s Valparaíso Region. IDE says the plant is designed to supply fresh water to multiple users, including municipal, industrial, agricultural and mining customers in the Aconcagua basin. ### Who is building what, and for whom? Aguas Pacífico SpA is the project company that awarded IDE the EPC contract, according to IDE’s earlier contract announcement and third-party industry coverage. The scope covers engineering, supply, construction, start-up and commissioning of the desalination plant, making IDE the turnkey delivery contractor rather than a narrow equipment supplier. (ide-tech.com) The Quintero Bay location matters because IDE’s materials place the plant on Chile’s central coast while linking its output to inland demand in the Aconcagua basin. That setup makes the project more than a standalone treatment facility; it is part of a broader water-delivery chain serving several end users across the region. ### Why does the 86,400 m³/day number matter? (watertechonline.com) The 86,400 cubic meters a day figure is the plant’s nominal production capacity, which IDE and industry publications also express as 1,000 liters per second. That is the number that defines the project’s scale in practical terms: intake, pretreatment, reverse-osmosis trains, pumping, power systems and discharge infrastructure all have to be sized around that throughput. (ide-tech.com) IDE’s project page says the plant is intended to serve municipal, industrial and mining clients, while earlier company statements also included agricultural users. That multi-client design is a notable feature because it means the plant is being presented as shared regional infrastructure rather than a captive desalination unit for a single mine or utility. (watertechonline.com) ### What makes this an EPC story rather than just a water story? The contract language is explicit about delivery. IDE says the award covers engineering, procurement, construction, start-up and commissioning, which is the classic full-EPC package. In practical terms, that means one contractor is responsible for integrating civil works, process equipment, electrical systems, piping, controls and handover performance. (ide-tech.com) IDE’s broader project portfolio shows the company works across EPC, BOT, O&M and other delivery models, but Aconcagua is presented specifically as an EPC desalination job in Chile. That distinction matters because turnkey accountability is central to how the company is framing execution. ### Where does this sit in the project timeline? March 20, 2023 is the date IDE said it commenced construction of the Aconcagua desalination plant in the Valparaíso Region. (watertechonline.com) That means the current company messaging is not announcing a new award; it is resurfacing or detailing a project already under construction. (ide-tech.com) A 2023 financing note from Carey said construction of the project was expected to be completed in 2025, tied to funding for both the Aconcagua desalination plant and the San Isidro Quilapilún aqueduct. Public materials surfaced in this search do not independently confirm final completion or commercial operation as of May 27, 2026. (ide-tech.com) ### What should readers watch next? IDE’s current reference points are its Aconcagua project page and related company materials, which continue to identify Quintero Bay, Aguas Pacífico SpA and the 86,400 m³/day capacity as the core project facts. Those are the clearest public markers for tracking any future update on start-up, commissioning or handover. (ide-tech.com) (carey.cl)
