Twenty-three thousand water professionals do not gather in one city every September by accident. WEFTEC — the Water Environment Federation's Technical Exhibition and Conference — has grown over 99 years into the largest annual water quality event in North America, and its scale reflects the genuine complexity and scope of modern water and wastewater infrastructure. Every municipal wastewater treatment plant, every industrial water recycling system, and every stormwater management facility in North America depends on equipment that gets evaluated, compared, and specified substantially through the relationships and product launches that happen on the WEFTEC exhibition floor.

WEFTEC 2026 runs September 26 to 30 at the Ernest N. Morial Convention Center in New Orleans, with the core exhibition running September 28 to 30 within that broader conference window. The 99th edition continues a recent run of record-breaking attendance, building on a particularly strong 2024 New Orleans edition and a successful 2025 Chicago show. Over 950 exhibitors and more than 23,000 water professionals from over 100 countries and 50-plus industries are expected, with 125-plus technical sessions running alongside the exhibition floor.

Where Hydraulics Fits in Water Treatment Infrastructure

Water and wastewater treatment plants are substantial hydraulic equipment consumers, even though the industry's public conversation focuses more on biological treatment processes, membrane technology, and disinfection systems. Sludge dewatering presses — belt presses, screw presses, and centrifuges — use hydraulic systems for the high-force compression that separates water from solid waste. Penstock and sluice gate actuators throughout a treatment plant's flow control infrastructure are frequently hydraulically operated, particularly at larger installations where the force required to move large gates exceeds practical electric actuator capability. Grit removal equipment, screw conveyors, and various mechanical handling systems throughout a treatment plant use hydraulic drives for their combination of high torque and controllable speed.

WEFTEC's exhibit categories explicitly include pumps alongside treatment equipment, sensors, automation, analytics, stormwater infrastructure, membranes, and chemicals — and the pump manufacturers exhibiting at WEFTEC, including major global players, present complete product ranges that span the hydraulic power units, actuators, and control systems that integrate with their core pumping technology. The buyer audience — utility engineers, plant operators, municipal procurement officers, and the engineering consultancies that design treatment plant upgrades — represents one of the most reliable, recurring capital equipment markets in any infrastructure sector, since water and wastewater treatment cannot be deferred indefinitely regardless of broader economic conditions.

The Documented Commercial Value

WEFTEC's own data shows exhibitors reporting an average of $495,000 in sales influenced by connections made at the show — a figure that reflects both the scale of capital equipment purchases in the water sector and the genuine purchasing authority of the attendees who walk the exhibition floor. Water utility capital projects are typically large, infrequent, and subject to extended public procurement processes, which means that the relationships and product evaluations that begin at WEFTEC often mature into purchase orders over a multi-year timeline rather than producing immediate transactions — a sales cycle that hydraulic equipment manufacturers serving this market need to plan for and sustain through consistent, repeated WEFTEC presence rather than one-off participation.

For hydraulic pump, actuator, and power unit manufacturers, WEFTEC offers access to the engineering and procurement community responsible for North America's multi-billion-dollar annual investment in water and wastewater infrastructure renewal and expansion. The technical session programme, covering emerging contaminants, energy efficiency in treatment processes, and the digitalisation of plant operations, provides useful context for understanding how hydraulic equipment specifications in this sector are evolving alongside the broader operational and regulatory pressures facing North American water utilities.
