One Water Technical Conference & Expo 2027
The One Water Technical Conference & Expo is the annual four-day technical conference and trade exhibition organised by One Water Ohio, a joint effort between the Ohio Water Environment Association (OWEA) and the Ohio Section of the American Water Works Association (AWWA), held for Ohio's water professionals. The 2027 edition runs August 23-26, 2027 at the Greater Columbus Convention Center, 400 North High Street, Columbus, Ohio 43215. The conference welcomes 2,000+ attendees together with 250+ exhibitors, and the exhibition component is staged as the One Water Exhibition on August 24-25, 2027 inside the exhibit hall. New for 2027: the Tuesday Exhibit Hall Mixer and the Meet & Greet are combined into one super-sized networking event inside the exhibit hall, giving attendees and exhibitors more uninterrupted networking time. Key dates: the call for abstracts opened in October 2026, sponsor enrollment opens November 2026, sponsor exhibitor registration opens January 2027, general exhibitor registration opens February 2027, and attendee registration opens April 2027. Booth packages for exhibitors require a 20% non-refundable deposit, with payment due in full by June 16, 2027. One Water Ohio also runs a separate one-day Government and Regulatory Affairs Workshop each March, and on-demand webinars between the main conferences.
