WEFTEC Chicago

The WEFTEC, an abbreviation for the "Water Environment Federation's Technical Exhibition and Conference", is regarded as the largest and most significant trade fair and conference for water quality in America. Organized by the Water Environment Federation, this annual event serves as a central meeting point for recognizing the latest developments in the water industry.

It is held at the McCormick Place Convention Center in Chicago, one of the most prestigious exhibition venues globally. Here, experts, professionals, and enthusiasts from various sectors gather, primarily from the fields of drinking water, water reuse, recovery, and wastewater treatment.

Key areas of focus at WEFTECc include the Drinking Water Pavilion, which emphasizes water reuse and drinking water treatment; the Drone Pavilion, which discusses inspections and data collection; and the Innovation Pavilion, showcasing cutting-edge products and startups.

Additionally, technologies specializing in the treatment and disposal of reused water - be it rainwater or wastewater - are introduced.

A highlight of Weftec is the awards for innovative products and the challenging "Operations Challenge" skill competition for water resource recovery facility staff. The event attracts numerous exhibitors and visitors who are constantly in search of the latest trends, technologies, and best practices in water management.
