Case study: 20-year partnership with International River Foundation

Thiess’ longstanding commitment to sustainable water management is underpinned by our status as a founding member of the International RiverFoundation (IRF), a not-for-profit organisation established in 2003 to champion the restoration, protection, and resilience of the world’s rivers. In association with the IRF, Thiess awards a biennial International Riverprize, recognising organisations who have achieved remarkable outcomes for their local rivers and communities.

In 2022, Thiess sponsored the 25th International Riversymposium in Vienna, bringing together experts from all over the world to advance efforts towards resilient rivers. In addition, Thiess Group Executive Chair and CEO Michael Wright, transitioned from his position as Director on the IRF Board to Chair.
