One Water is a joint effort between OWEA and OAWWA and replaces both organizations' separate conferences.

We require a ticket for everyone--regardless of age--for all of our events. You can either purchase the Guest Package which includes all event tickets or you can purchase a singular event ticket a la cart. If your spouse/family/children/friend will not be attending One Water events then no further action is necessary.

You can earn up to 17.5 hours from a Full Conference registration.

We encourage you to purchase additional event tickets ahead of time through your conference registration. If you need to add tickets after you have registered, but before August 2, 2023, you can contact the office to add them for you. Tickets can also be purchased at the registration desk during the conference but could involve significant wait times.

No. Substitutions are welcomed without penalty. Written substitution must be submitted by the original registrant by August 2, 2023 in order to be processed before the conference. Substitutions needed after August 2, 2023 must be done onsite. Partial substitutions are not allowed. Registrants must transfer their entire registration to a new person, not just a portion.

One Water can accept VISA, MasterCard, Discovercard, and American Express credit cards payments
