Member Rate Qualifications:
To qualify for member rates, you must have a current individual WEF or IWA membership, valid through the event date. You should have your own individual member ID number. Though your institution may be a member of WEF, you must maintain an individual WEF membership to be eligible to receive the member rate. Learn more about WEF Membership.

If you are not a member or your membership lapses and is not renewed by the time of the event, you will either have to join/renew your membership or pay the non-member rate for the event.

Students that are not a member of WEF must pay the student nonmember rate and provide proof of student status.

Online registration payments are by credit card only (Visa, Mastercard, or American Express).

Cancellation and Substitution: 

A written request for cancellation/refund must be submitted by April 28, 2023. WEF will charge a 25% cancellation fee and refund 75%. No refunds will be issued for cancellations requested after April 28, 2023. Rather than canceling, consider sending a substitute. An organization may submit a request to substitute one person for another in writing by April 28, 2023.
