01 / Make the call
Is this the right room?
Emitree's assessment of audience fit. Conference access does not establish buying intent or guarantee meetings.
Consider it if
You sell water treatment technology, desalination, non-revenue water management, or wastewater resource recovery solutions to utilities, and want a global, research-adjacent audience with strong UK and European utility representation.
Consider another event if
You need the full congress program on a small budget, or a purely commercial, sales-floor audience. Congress passes start at GBP 1,090 plus 20% VAT for high-income-country non-members, and the program leans toward utilities and researchers alongside buyers. Exhibition-only trade access is free, so floor-walking is the cheap way in.
02 / Understand the audience
Who attends
IWA projects over 10,000 participants from more than 100 countries for Glasgow across the Congress and Exhibition combined, an organizer target well above the roughly 1,461 congress participants its own site reports for the 2024 Toronto edition. The projected room spans utility leaders, academics, government and NGO representatives, technology providers, consultants, and media. Principal sponsor is RSE; platinum sponsors are Grundfos and Xylem.
How large is the event?
IWA projects over 10,000 participants for Glasgow 2026 across the Congress and Exhibition combined, an organizer target for an event that has not happened yet. The official homepage cites the prior 2024 Toronto Congress at roughly 1,461 congress participants with 53 exhibitors, while a separate page on the same site shows different, apparently partial, figures for the same edition. Treat exact past attendance as directional.

The practical questions
Before you decide
Is IWA World Water Congress & Exhibition 2026 still upcoming?
This edition ended on October 8, 2026. We have no later confirmed edition in this guide. Use the information as historical context.
Where can I find the IWA World Water Congress & Exhibition exhibitor list?
We have not linked a public exhibitor directory for this edition. Ask the organizer about current directories and attendee access.
Does a company listing confirm who will attend?
A sponsor, exhibitor or speaker listing establishes that published role. It does not establish which employees will attend or whether they are buying. Previous-edition examples remain historical.
How can Emitree help with IWA World Water Congress & Exhibition?
We can research relevant accounts and prepare follow-up using your event notes, contacts and public sources. We qualify the accounts against your offer and run agreed outreach in your team's voice.
