We are so excited to be heading to Columbus August 23-26! This four day event will bring 2,300+ water professionals and 300+ exhibitors together for networking and continuing education. In 2026, we hit a milestone of over 2,250 attendees in Cincinnati! Columbus’s central location historically brings the largest crowds so we are anticipating yet another record-breaking year.

As a sponsor you will receive recognition at all the conference events, the One Water Ohio website, and reach public and private owners of wastewater treatment and drinking water facilities, Ohio cities and counties, consultants, engineers, operators, laboratory analysts, public utility managers, and Ohio EPA staff. Past One Water conferences have yielded attendees from far and wide. Your exposure will spread across the region and beyond.

This is an industry built on relationships and One Water fosters relationship building through engaging training events that benefit all sectors of the water industry. We know that while we each play a different part in Ohio’s water story, and together we are One Water.
