Compras MX now lists 24 July at 11:00 for proposal opening and 29 July at 17:00 for the ruling on Rosarito's first 2,200 l/s desalination module. The live record includes a notice deferring the opening date and replaces the earlier 21 and 24 July programme dates.

Published scope and current milestone

The live Compras MX detail gives the current timetable, vigente status, evaluation split, advance, guarantees and delivery term. The federal project register provides the first-module capacity and wider programme. The September 2025 agreement identifies the wider 2,200 l/s project components, while SEMARNAT's 2024 filing describes a larger 4,400 l/s full-site environmental envelope. No award is public, and the available documents do not show that every component in the 2025 agreement forms part of the current invitation.

Marine-system delivery and operating implications

The procedure remains vigente and now discloses a 50:50 technical-economic points split, a 30% advance, a 10% performance guarantee and separate liability and environmental insurance each at 10%. The plant is tied to a real coastal utility system, but the current description still names the desalination plant and pumping plant without defining which intake, brine-discharge or CFE connection works sit inside the invited package.

Evidence conclusion

Testing, acceptance and operating evidence

The procurement is active on a changed timetable and has not reached award. The invited firms and selected contractor are not named. The 1,096-day term and 1 August physical-start date are tender-stage plans. The 4,400 l/s capacity in the 2024 environmental file describes the full-site envelope; the current procurement is for a 2,200 l/s first module.
