    Rio Tinto–WA A$1.1bn desalination JV: water security lens for Pilbara mines

    March 5, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Rio Tinto and the Western Australian Government have formed a 50:50 joint venture to deliver the A$1.1 billion Dampier Seawater Desalination Plant, comprising Stage 1 and Stage 2. When fully operational, the plant will supply 8 GL/y of desalinated water into the West Pilbara Water Supply Scheme, easing demand on stressed regional aquifers that currently support mining and communities. For mine planners and water engineers, the scheme signals a shift towards coastal desalination as a primary source for Pilbara process and potable water security.

    Technical Brief

    • Reduced abstraction from stressed regional aquifers will alter long-term hydrogeological drawdown and recharge behaviour.
    • The joint venture model provides a template for co-funded desalination in other resource-dependent regions.

    Our Take

    A 50:50 JV structure between Rio Tinto and the Western Australian Government on the Dampier Seawater Desalination Plant signals an unusual degree of public-sector risk sharing for a mine-adjacent A$1.1 billion water asset, which could set a template for future Pilbara infrastructure where social licence and long-life water security intersect.

    Adding 8 GL per year into the West Pilbara Water Supply Scheme gives Rio Tinto more headroom to decouple iron ore production growth from groundwater abstraction limits, which have been a binding constraint for several operators in Western Australia in our Infrastructure coverage.

    Within the 726 Infrastructure stories and 2042 tag-matched pieces in our database, very few large-scale desalination projects in Australia feature such a clear sustainability framing, suggesting Rio Tinto is positioning this asset as both a production enabler and a visible decarbonisation and climate-resilience measure for its Pilbara operations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.

    Hudson Tunnel funding deadline: schedule and risk takeaways for project teams

    Federal funding for New York’s US$16bn Hudson Tunnel Project has been frozen, forcing the Gateway Development Commission to suspend works from 6 February after spending over US$1bn and employing about 1,000 site workers. A Manhattan federal judge has issued a temporary restraining order, giving the administration until 5 p.m. on 12 February to restore reimbursements or appeal, while contractors warn that demobilisation, resequencing and remobilisation will add cost and delay. Sites are now in “safe-pause” mode, with dewatering, ground support and environmental monitoring maintained, and assembly of two Herrenknecht TBMs in New Jersey likely to slip beyond the planned spring 2026 launch without funding certainty.

    Implenia/Marti JV MehrSpur Zurich–Winterthur: design and risk notes for engineers

    Swiss Federal Railways has awarded an Implenia/Marti 50:50 joint venture five of six MehrSpur Zurich–Winterthur lots worth just under CHF 1.7 billion, including the 8.3 km Brüttener tunnel (Lot 240) with twin 10 m diameter single-track tubes and a 1 km spur to Zurich Airport. TBM excavation will start in August 2029, with a roughly ten-year construction phase using BIM for planning and execution and extensive special foundations, earthworks and embankments. Additional works cover full redevelopment of Dietlikon station, about 6 km of new track across Dietlikon and Wallisellen sections, multiple underpasses, bridges and the Neumühle railway bridge and Storchen underpass near Winterthur.
