History
The history of the WWETT Show begins in 1979, when a tiny, trimmed-down newspaper was developed and mailed to around 12,000 septic “pumpers” throughout the Midwest — the first edition of The Midwest Pumper. By 1981 a conference had grown out of it — The Liquid Waste Hauler's Equipment & Trade Show — consisting of a few hundred attendees and a couple dozen exhibitors.
Since 2015, the WWETT Show has evolved into the world's largest tradeshow for wastewater and environmental services professionals, hosting over 13,500+ individuals in Indianapolis every year. The WWETT Show is now also recognized as one of the premier tradeshows across all industries, earning distinctive honors like Trade Show Executive's Gold 100 Award in 2024, recognizing the largest 100 trade shows in the United States. The show is organized by Informa Markets.
