INDIANAPOLIS – In the world of environmental services, there is no single event that brings together the boots-on-the-ground professionals quite like the WWETT Show. Officially standing for Water & Wastewater Equipment, Treatment & Transport, this annual gathering has grown from a modest regional meetup into the largest trade show in North America dedicated to onsite wastewater, portable sanitation, industrial cleaning, and municipal sewer maintenance.
For over two decades, the WWETT Show has transformed the Indiana Convention Center into a sprawling showcase of heavy iron, high-pressure water, and the latest technology for managing what the industry delicately calls “the flow.” But as the industry looks ahead to 2027, the show is evolving far beyond just portable toilets and vacuum trucks.
What Is the WWETT Show?
At its core, the WWETT Show is where the environmental service industry conducts business. Unlike the science-heavy, academic vibe of WEFTEC (which focuses on municipal treatment plant design), WWETT is unapologetically practical and hands-on.
Picture this: Over 500 exhibitors packing more than 200,000 square feet of floor space. You will see massive vacuum trucks, hydro-excavation units, sewer cleaners, high-pressure jetting equipment, CCTV pipe-inspection robots, and rows upon rows of portable sanitation units. But you won’t just look at them—at WWETT, you can actually test-drive this heavy equipment in the famous outdoor “Mud Pit,” a unique demonstration area where attendees get behind the wheel in real-world, muddy conditions.
Beyond the exhibition hall, the show offers over 100 educational sessions, including OSHA safety courses, confined-space entry training, and certification programs through the National Association of Wastewater Technicians (NAWT). It is as much about professional development as it is about buying new trucks.
Who Attends?
The attendee roster is a cross-section of the entire industry:
- Septic and Portable Toilet Contractors – the backbone of the event, running small to medium-sized businesses.
- Municipal Sewer and Stormwater Crews – city workers responsible for maintaining underground infrastructure.
- Industrial Cleaning Companies – specialists in tank cleaning, hydro-blasting, and hazardous waste remediation.
- Environmental Consultants and Inspectors – professionals ensuring systems meet regulatory compliance.
- Manufacturers and Upfitters – the engineers and fabricators building the equipment these contractors rely on.
In recent years, attendance has consistently hovered around 8,000 to 10,000 participants, making it an intimate but highly focused gathering compared to mega-shows like CONEXPO.
2026 & 2027: What’s on the Horizon?
Dates and Location
WWETT 2027 will take place February 22–25, 2027 at the Indiana Convention Center.
Key Trends Shaping the 2027 Show
The environmental service industry is undergoing its most significant transformation in decades. Here are the trends that will dominate the WWETT Show floor and educational sessions:
1. Electrification Moves from Concept to Production
For years, electric vacuum trucks were a novelty—prototypes shown in corner booths. By 2027, that changes. Major OEMs are rolling out production-model EV chassis specifically designed for PTO (Power Take-Off) equipment. Cities with strict idle-time and emissions mandates are driving this demand, and contractors are starting to calculate the total cost of ownership savings. At WWETT, expect to see real-world runtime data, charging solutions, and side-by-side comparisons of diesel vs. electric.
2. The PFAS Crisis Comes Home
Per- and polyfluoroalkyl substances (PFAS)—the so-called “forever chemicals”—are the single most disruptive regulatory force in the water industry. With the EPA rolling out new Maximum Contaminant Levels (MCLs) for drinking water and stricter rules on land-applying biosolids, wastewater contractors are suddenly on the front lines. The 2026 and 2027 shows will feature dedicated sessions on PFAS containment, filtration, hauling, and disposal, alongside new equipment designed to separate contaminated sludge from clean water.
3. AI and Autonomous Inspection
CCTV pipe inspection used to mean a technician manually driving a crawler through a sewer line while watching a grainy monitor for hours. Artificial intelligence is rapidly changing that. By 2027, AI-powered inspection robots will be mainstream—capable of automatically detecting cracks, root intrusion, pipe deflection, and even estimating remaining wall thickness without human intervention. The technology generates detailed repair estimates instantly, slashing labor costs and improving accuracy.
4. Telematics Becomes a Contract Requirement
Major municipalities are increasingly mandating real-time telematics on all contracted vacuum trucks. GPS location, pump runtime, tank levels, and job duration are being tracked and submitted with invoices for payment verification. At WWETT, manufacturers are showcasing factory-integrated telematics solutions that turn the truck cab into a mobile command center.
5. The Labor Shortage Drives Automation
With skilled operators in short supply, equipment manufacturers are focusing on ease of use. Look for one-button automated jetting sequences, self-diagnosing pump systems, and simplified touchscreen controls that allow less-experienced workers to operate complex equipment safely and productively.
The Indianapolis Advantage
One of the WWETT Show’s biggest assets is its permanent location. Indianapolis is a central, easily accessible hub for the heavy-truck industry, and the Indiana Convention Center is purpose-built for large equipment displays. The city’s downtown hotels, restaurants, and airport offer seamless logistics for the thousands of out-of-state attendees hauling in from rural and suburban communities across America.
Planning for WWETT 2027 and Beyond
If you’re planning to attend, exhibit, or exhibit, here are some practical considerations:
- Book Early: Indianapolis hotels near the convention center sell out 10–12 months in advance. The JW Marriott, Hyatt, and Embassy Suites are prime targets.
- Register Early: Early-bird registration rates and educational session slots fill quickly.
- Bring Your Boots: The outdoor demo area (“The Mud Pit”) is a must-see, and you’ll want appropriate footwear.
- Mark your calendar.
The WWETT Show is far more than a trade show—it is the annual gathering of an industry that keeps modern civilization running smoothly, quietly, and hygienically. As environmental regulations tighten, technology advances, and the workforce evolves, WWETT remains the essential forum where contractors, manufacturers, and regulators come together to solve the dirtiest problems with the smartest solutions.
Whether you’re a septic contractor from rural Iowa, a municipal crew chief from Chicago, or a manufacturer launching the next-generation EV vacuum truck, the WWETT Show is where the dirty work gets done—and where the future of the industry takes shape.
