Preliminary Program

The IDRA World Congress 2026 brings the global desalination and water reuse community to Riyadh for five days of dialogue, deep-dives, and decisions.

Hosted by the Saudi Water Authority under the patronage of the Ministry of Environment, Water and Agriculture, the Congress unites policymakers, utilities, developers, financiers, researchers, and innovators around a single purpose: accelerating the technologies, partnerships, and policies the world needs to deliver water security at scale.

Across four full days plus the Water Regulations Forum and Pre-Congress Workshops, the program moves from global framing through finance, energy, reuse, technology, and policy, building a unified industry voice on the road to the 2026 UN Water Conference in the United Arab Emirates.
