Water & wastewater trade shows 2027: treatment, pipe, waste & recyclingEveryone needs water. Few people buy the pumps.

WEFTEC, with 20,000+ water professionals from 100+ countries and more than 950 exhibiting companies, per WEF. On the waste side, WasteExpo cites 14,500+ participants and the WWETT Show 14,000+ professionals; AWWA ACE counted 11,403 total registrants at ACE25. The Top 8 on this page lists every figure with its source.

WEFTEC 2027 runs September 25–29, 2027 at McCormick Place in Chicago. The 2026 show was in New Orleans, where WEF expected more than 23,000 water professionals, exhibitors and industry leaders. See the WEFTEC exhibitor page.

Yes. WEF requires every WEFTEC exhibitor to provide booth flooring, except in the Innovation Showcase and Discovery Zone, and publishes a sample booth budget for exhibitors. Plan the carpet or a raised deck as part of the build.

Pick by the water you treat. WEFTEC centers on wastewater and water quality, with treatment process, pumps, blowers, membranes and biosolids. ACE27 centers on drinking water utilities, with pipe, valves, hydrants, meters and AMI, treatment and utility software. Many pump, instrument and treatment makers do both: ACE27 in June in San Diego, WEFTEC in September in Chicago.

Two: the WateReuse Symposium at Caesars Palace, March 1–4, 2027, and WasteExpo in the Las Vegas Convention Center West Hall, May 3–6, 2027. Our Las Vegas shop builds in the same city.

The ISRI Convention. ReMA, the Recycled Materials Association, is the Institute of Scrap Recycling Industries under its new name. The ReMA Show 2027 runs April 12–15, 2027 at Music City Center in Nashville, and ReMA describes it as bringing together more than 6,000 buyers, sellers, processors, traders and industry leaders.

Yes. RCon is SWANA’s event that took the place of WASTECON and SOAR. It began in 2025 with nearly 1,700 attendees in Columbus, and the 2026 edition drew more than 1,500 professionals to St. Louis. RCon 2027 runs September 21–24, 2027 in Portland, Oregon; the venue is not confirmed yet.

March 1–4, 2027 at Caesars Palace in Las Vegas, with an exhibit area beside the sessions. The Water Research Foundation is the presenting partner, and past exhibitors include AECOM, Badger Meter, DuPont Water Solutions and Energy Recovery.

The 2027 edition runs March 1–3, 2027 at the Gaylord National Resort & Convention Center in National Harbor, Maryland, with the Resource Recycling Conference and the Textile Recovery Summit. The 2028 edition moves to Denver, March 20–22. See the conference page.

May 10–13, 2027 at the Kentucky International Convention Center in Louisville. It is the American Biogas Council’s annual conference, and the 2028 edition moves to Pittsburgh. See BIOGAS AMERICAS 2027.

No. The RNG Conference 2026 runs December 7–10, 2026 at the Waldorf Astoria Monarch Beach Resort & Club in Dana Point, California, and companies take part through host and sponsor packages rather than a booth hall. Gas upgrading, analytical, engineering and project finance companies are the usual hosts.

Three in early 2027: the Underground Infrastructure Conference (January 26–27, Gaylord Texan, Grapevine; 1,200+ engineers, contractors, managers and operators, per UIC), the WWETT Show (February 22–25, Indianapolis) for sewer and drain contractors, and the NASTT No-Dig Show (March 21–25, Raleigh) for HDD, pipe bursting and CIPP.

Both have one. WEFTEC’s Discovery Zone in the Innovation Neighborhood is for startups and first-time exhibitors, the New Exhibitor Pavilion groups companies making their debut, and the Innovation Showcase is presented by WEF, BlueTech Research and Imagine H2O. AWWA runs the Innovation Hub at ACE, a curated area for new water technologies with its own education program.

March, with three: the WateReuse Symposium and the Plastics Recycling Conference both open March 1, and the No-Dig Show follows March 21–25. April (ReMA and WQA), May (WasteExpo and BIOGAS AMERICAS) and September (RCon and WEFTEC) each hold two.

At the Phoenix Convention Center, April 28–30, 2027. WQA moves the show around the U.S. each year, and its floor brings softeners, filtration, reverse osmosis and point-of-entry and point-of-use systems to water treatment dealers. See WQA 2027.

Yes. We design and build custom booths from 10×20 up, including decks for heavy equipment, plus graphics and counters for tabletop and sponsor spaces. We build in our Fishkill, NY and Las Vegas shops, with fixed proposals, 30–45 day builds and your own project manager on the floor, who runs the install with the labor each hall requires.
