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 reuse or reclaimed water technology (advanced treatment, membranes, potable reuse systems) or water stewardship consulting, and you want the utility engineers, regulators, and researchers who set reuse policy and specify equipment.
Consider another event if
Your buyers sit outside municipal or industrial water reuse. The room skews to utility and engineering staff, not general corporate sustainability buyers.
02 / Understand the audience
Who attends
Water utility staff, engineers, regulators, researchers, and water reuse technology and service providers, drawn from across the US and internationally. Trade press coverage of the 2025 Symposium (its 40th anniversary) put attendance at more than 1,000 water industry professionals. The organizer does not publish per-edition headcounts, and no figure is available yet for 2027.
How large is the event?
Trade press put the 2025 Symposium (40th annual) at more than 1,000 attendees. No attendance figure is available for 2027, and registration had not opened as of late August 2026.

The practical questions
Before you decide
Is WateReuse Symposium 2027 (42nd Annual) still upcoming?
This edition is listed for March 1–4, 2027. Check the organizer's page for changes before booking.
Where can I find the WateReuse Symposium 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 WateReuse Symposium?
We research relevant accounts using public conference sources and any lists you provide. We qualify the accounts against your offer, run agreed outreach and record replies and meetings in your CRM.
